This paper provides a comprehensive summary of evidence to explore and position the role of serology testing in the context of coronavirus disease 19 (COVID-19) immunization and policy response in the Asia-Pacific (APAC) region. The document builds on a review of academic literature and existing policies followed by a process of discussion, validation, and feedback by a group of six experts. Six countries and territories—Australia, Hong Kong, India, Indonesia, Thailand, and Taiwan—were sampled to highlight the differing contexts and scenarios in the region. The review includes an overview of (1) the impact of the COVID-19 pandemic, including the emergence of Variants of Concern (VOCs), especially Omicron, (2) the introduction of immunization, (3) the available testing options and potential use of serology testing, (4) the landscape of guidelines and recommendations for their use, and (5) the barriers and challenges to implementing serology testing as a tool to support COVID-19 immunization. Based on the findings, the co-authors propose a set of recommendations to resolve knowledge gaps, to include the use of serology testing as part of the policy response, and to ensure adequate means of implementation. This paper's target audience includes members of the academic community, medical societies, health providers and practitioners, and decision-makers. [ABSTRACT FROM AUTHOR]

My Turn is software used to manage several Covid-19 mass vaccination campaigns in California. The objective of this article is to describe the use of My Turn at two points of dispensing in California and comment on process improvements to reduce manual tasks of six identified processes of vaccination–registration, scheduling, administration, documentation, follow-up, and digital vaccine record–and paper. We reviewed publicly available documents of My Turn and patients vaccinated at George R. Moscone Convention Center in San Francisco and Oakland Coliseum Community Vaccination Clinic. For publicly available documents of My Turn, we examined videos of My Turn on YouTube, and documentation from EZIZ, the website for the California Vaccines for Children Program. For patients, we examined publicly available vaccination record cards on Instagram and Google. At the George R. Moscone Convention Center, 329,608 vaccines doses were given. At the Oakland Coliseum Community Vaccination Clinic, more than 500,000 vaccine doses were administered. The use of My Turn can be used to reduce manual tasks and paper for mass vaccinating patients against Covid-19. [ABSTRACT FROM AUTHOR]

Objectives: To map the current evidence about the health concerns and the potential solutions related to the Islamic pilgrimage to Mecca. Design: A scoping review was applied. Papers published in English between 2012 and 2023 were included but non‐human research and sources without any related data were excluded. Data charting and extraction were used to map the current evidence. Results: The total of 36 papers were included with the total number of pilgrims of 17,075,887. The majority of studies were published in the Asia Pacific region (36.11%) as original articles (88.89%). The health concerns were grouped into five main aspects. There were 7603 deaths recorded or about 44 incidences of deaths per 100,000 pilgrims during the pilgrimage. There were recorded 11,018; 6178; 3393; and 17,810 cases for communicable diseases; non‐communicable diseases; injuries and trauma; and health services (i.e., cardiac catheterization) and vaccination, respectively. Conclusion: Relating to the five health concerns, this study identified the top seven issues in each category (i.e., hypertension, influenza vaccination), except for the death record. Moreover, there were three solutions (for general health, non‐ and communicable‐diseases) presented. Stakeholders could use this evidence to improve healthcare quality particularly related to the annual Islamic pilgrimage to Mecca. [ABSTRACT FROM AUTHOR]

The recent Typhoid Fever Surveillance in Africa Program demonstrated an overall adjusted incidence of typhoid fever 2–3 times higher than previous estimates in Africa. Recently, a single-dose typhoid conjugate vaccine that allows infants as young as 6 months old to be vaccinated was prequalified by the World Health Organization (WHO). This Vi-based conjugate vaccine demonstrated robust immunogenicity after 1 dose in infants and children 6 through 23 months of age in India with no safety signal, and is currently being tested for the first time on the African continent in Malawi. The WHO Strategic Advisory Group of Experts recommends studies to evaluate co-administering Vi-typhoid conjugate vaccine (Vi-TCV) with routine childhood vaccines in typhoid-endemic countries. The Burkina Faso immunization schedule includes yellow fever vaccine (YFV) at 9 months and meningococcal A conjugate vaccine (MCV-A) at 15 months, in addition to measles-rubella vaccine at both 9 and 15 months. Co-administration testing of Vi-TCV with these routine vaccinations will provide the data needed to support large-scale uptake of Vi-TCV in sub-Saharan Africa. A randomized, controlled, Phase II trial of Vi-TCV co-administration with the vaccinations routinely given at 9 and 15 months of age is planned in Burkina Faso. The overall aim is to assess the safety and immunogenicity of Vi-TCV when co-administered with YFV at 9 months of age and with MCV-A at 15 months of age. A total of 250 participants (100 infants aged 9–11 months and 150 children aged 15–23 months) will be enrolled. Clinical Trials Registration. NCT03614533. [ABSTRACT FROM AUTHOR]

This article presents the World Health Organization’s (WHO) recommendations on the use of cholera vaccines excerpted from the Cholera vaccines: WHO position paper, August 2017 , published in the Weekly Epidemiological Record (Cholera vaccine, 2017) [1] . This position paper replaces the 2010 WHO position paper on cholera vaccines (Cholera vaccine, 2010) [2] . It incorporates the most recent evidence on cholera vaccination and provides revised recommendations on the target populations for cholera immunization. Footnotes to this paper provide a number of core references including references to grading tables that assess the quality of the scientific evidence, and to the evidence-to-recommendation table. In accordance with its mandate to provide guidance to Member States on health policy matters, WHO issues a series of regularly updated position papers on vaccines and combinations of vaccines against diseases that have an international public health impact. These papers are concerned primarily with the use of vaccines in large-scale immunization programmes; they summarize essential background information on diseases and vaccines, and conclude with WHO's current position on the use of vaccines in the global context. Recommendations on the use of cholera vaccines were discussed by the Strategic Advisory Group of Experts (SAGE) in April 2017; evidence presented at these meetings can be accessed at: www.who.int/immunization/sage/meetings/2017/April/presentations_background_docs/en/ .

Parental decision making is necessary for contracting medical interventions that require personal risk–benefit evaluation, and for overseeing matters of education. In the nineteenth century, exemptions from obligatory vaccination were granted for religious and conscientious reasons. Then and today, religion and moral values play marginal roles in vaccine hesitancy and denialism. Rather, the key values invoked by vaccine hesitants and denialists are liberty and pluralism. Neither is compatible with limiting adolescents' choice. Because vaccination does not require assessment of personal medical risks, because it does not need to occur within the sphere of the doctor–patient relationship, and because the risk involved is within the range of their daily activities, adolescents have the right to free access to vaccination without legal requirement of parental involvement. Drawing on the development of Common Law, and on the development of respect for personal conscience in the history of ideas, this paper does not promote an argument that grants public health an overriding moral power. Rather, this paper rejects the presumption that vaccination of adolescents might involve a conflict between parental authority and public health. Free access to vaccination is compatible with the law and ethics of adolescents' evolving autonomy in relation to healthcare. [ABSTRACT FROM AUTHOR]

Objective: Publication science is the scholarly study of various aspects of the academic publishing process. Its applications to COVID-19 literature have been limited. Here, we describe COVID-19 submissions to, and resulting articles published by, the journal Public Health Reports (PHR), an important resource for US public health practice. Methods: We reviewed PHR 's COVID-19 submissions and articles published between March 27, 2020, and March 27, 2023. We coded each article for article type, author affiliation, the categories listed in PHR 's call for COVID-19 papers, and the public health emergency preparedness and response capabilities from the Centers for Disease Control and Prevention (CDC). Results: During the study period, PHR received 1545 COVID-19 submissions and published 190 of those articles in a collection, COVID-19 Response. The COVID-19 Response collection included 102 research articles, 29 case study/practice articles, and 24 commentaries. The corresponding author of more than half (52.1%; n = 99) of the articles was affiliated with academia. By the categories listed in PHR 's call for COVID-19 papers, 51 articles addressed health disparities, 38 addressed public health surveillance, and 34 addressed COVID-19 vaccination. By the CDC public health emergency preparedness and response capabilities, 87 articles addressed public health surveillance and epidemiologic investigation, 38 addressed community preparedness, and 32 addressed community recovery. The percentage of articles focused on policy/law was higher early in the pandemic (2020-2021) than later (2022-2023) (9.5% vs <3.0%). During the latter period, articles largely focused on vaccination (12.8%) and contact tracing (10.6%). Conclusions: Articles published in PHR 's COVID-19 Response collection covered a broad range of topics and were authored by contributors from diverse organizations. Our characterization of the COVID-19 output of a representative US public health practice journal can help academic publishing better address informational needs of public health responders.

Background: This paper discusses the stages of health system resilience (HSR) and the factors underlying differences in HSR during the covid-19 pandemic, especially the vaccination challenge. We studied the relationship between vaccination strategies and macro-context backgrounds in 21 Latin American countries. Our objective was to capture the impact of those aspects in the SR and identify potential improvements for future crises and for vaccination programs in general. Methods: The study uses mixed-methods research to provide insights into how the countries' backgrounds and vaccination strategies impact the HSR. Particularly, we used explanatory sequential mixed methods, which entails a quantitative-qualitative two-phase sequence. The quantitative phase was conducted using cluster and variance analysis, in which the HSR was measured using as a proxy the covid-19 vaccination outcomes in three cut-offs of reaching 25%, 50%, and 75% of population coverage. This approach allows us to discriminate covid-19 vaccination progress by stages and contrast it to the qualitative stage, in which we performed a country-case analysis of the background conditions and the changes in vaccination strategies that occurred during the corresponding dates. Results: The paper provides a rich comparative case analysis of countries, classifying them by early, prompt, and delayed performers. The results show that differences in vaccination performance are due to flexibility in adapting strategies, cooperation, and the ability to design multilevel solutions that consider the needs of various actors in the health ecosystem. These differences vary depending on the vaccination stage, which suggests the importance of acknowledging learning, diffusion, and feedback processes at the regional level. Conclusions: We identified the importance of societal well-being as an ideal country antecedent for high and sustained levels of performance in covid-19 vaccination. Whereas in other countries where the set-up and beginning phases were rough, the value of the operational decisions and the learning on the move regarding their own and their peers' trajectories were crucial and were reflected in performance improvement. A contribution of this study is that the above-mentioned analysis was done using vaccination coverage cut-off points that allow a performance view that takes into consideration the stages of the vaccination progress and the learning process that goes with it. As well as framing this into the HSR shock cycles that allow to differentiate the stages of resilience on which countries must act. [ABSTRACT FROM AUTHOR]

Background: Vaccination is the most important public health practice for preventing infectious diseases and maintaining health. However, some parents are hesitant to vaccinate their children. Design: This study was designed as an instrument development study. Methods: This study aimed to develop a scale to measure the attitudes of parents with children aged 0–5 years towards vaccination and to evaluate the validity and reliability of this scale. The data were collected from 691 participants between November 2020 and January 2021. During the development of the scale, experts provided feedback on its technical, content and language dimensions. The data were analysed using exploratory and confirmatory factor analyses for conceptual validity and Cronbach's α and item‐level test–retest analyses for reliability. Results: The developed scale is a reliable and valid tool for measuring attitudes towards vaccination among parents (Cronbach's α = 0.97, variance explained by these 28‐item two factors = 62.47%). Conclusion: This scale can be used as a guide in measuring the attitudes of parents towards vaccination and determining the direction of primary health‐care services based on the results of the measurement. Summary statement: What is already known about this topic? Vaccination plays an important role in health practice.Parents' attitudes towards vaccination affect their children's vaccination status.Increasing vaccination rates in children will contribute to the reduction of infectious diseases and mortality. What this paper adds? A new valid and reliable measurement tool for determining vaccine hesitancy has been developed.The validity and reliability of the scale of attitudes towards vaccination among parents of children aged 0–5 years were tested.The tool could be used to determine the attitudes of parents of children aged 0–5 years towards vaccination. The implications of this paper The scale may help in determining factors affecting parents' attitudes on vaccination.The scale can generate data to guide nursing practices to increase vaccination rates.The scale can be used to influence nursing practices to increase vaccination rates and promote vaccine awareness, trust and acceptance.

Background: Vaccination is a crucial protective intervention to prevent adult mortality and morbidity. Personal perceptions and resources have an important place in the vaccination decision. Aim: This study aimed to modify the Public Attitude Towards Vaccination–Health Belief Model scale for adult vaccines and evaluate its psychometric properties. Methods: Overall, 626 people participated in this methodological study. Content validity index, confirmatory factor analysis, internal consistency and item‐total score correlation were used for validity and reliability. The independent samples t test, logistic regression analysis and ROC analysis were used for criterion and concurrent validity. Results: In confirmatory factor analysis, values of fit indices were excellent or acceptable. The Cronbach alpha value was between 0.83 and 0.92. According to criterion validity, the susceptibility, severity, benefit, and health motivation scores of those with the vaccine were higher than those without, whereas their barrier score was lower. The barrier subscale was a risk factor, whereas the benefit score was a protective factor that increased the likelihood of vaccination. The concurrent validity of the scale was tested with the COVID‐19 vaccine. While the barrier subscale's ability to distinguish between vaccinated (specificity) and unvaccinated (sensitivity) individuals is excellent, it is acceptable for the other subscales. Conclusion: Modified PAVS‐HBM is valid and reliable for adult vaccines. This scale was associated with vaccination behaviour and distinguished between vaccinated and unvaccinated individuals. Summary statement: What is already known about this topic? Vaccination rates are low in many countries due to issues of access, economy and infrastructure and in countries that provide vaccines.Low vaccination rates in adults are associated with mortality and morbidity.Vaccination management success is enhanced by orientation towards individual perceptions. What this paper adds? The modified Public Attitude Towards Vaccination Scale–Health Belief Model (PAVS‐HBM) was demonstrated as a reliable and valid scale.This scale explains the vaccination behaviour for different adult vaccines.This scale's ability to distinguish between vaccinated (specificity) and unvaccinated (sensitivity) individuals is acceptable to excellent. The implications of this paper for practice: The scale can be used as a tool for researchers to evaluate the probability of individuals being vaccinated and to determine risk groups for vaccine refusal.It can be integrated with many models focused on behaviour change, and when used with a health model, the scale's explanation of individuals' vaccination behaviour can guide the structuring of nursing interventions for vaccination.

Immunization is highly effective in preventing infectious diseases and therefore an indispensable public health measure. Allergic patients deserve access to the same publicly recommended immunizations as non-allergic patients unless risks associated with vaccination outweigh the gains. Whereas the number of reported possible allergic reactions to vaccines is high, confirmed vaccine-triggered allergic reactions are rare. Anaphylaxis following vaccination is rare, affecting <1/100 000, but can occur in any patient. Some patient groups, notably those with a previous allergic reaction to a vaccine or its components, are at heightened risk of allergic reaction and require special precautions. Allergic reactions, however, may occur in patients without known risk factors and cannot be predicted by currently available tools. Unwarranted fear and uncertainty can result in incomplete vaccination coverage for children and adults with or without allergy. In addition to concerns about an allergic reaction to the vaccine itself, there is fear that routine childhood immunization may promote the development of allergic sensitization and disease. Thus, although there is no evidence that routine childhood immunization increases the risk of allergy development, such risks need to be discussed. [ABSTRACT FROM AUTHOR]

Background The COVID-19 pandemic demanded quick exchanges between experts and institutions supporting governments to provide evidence-based information in response to the crisis. Initially, there was no regular cross-country forum in the field of population health. This paper describes the set-up and benefits of implementing such a forum. Methods A group of public health practitioners from academia, national public health institutes and ministries of health decided in April 2020 to meet bi-monthly to discuss a vast array of population health topics in a structured format called a Rapid Exchange Forum (REF). An ad-hoc mailing group was established to collect responses to questions brought forward in the forum from at least five countries within 24 h. This endeavour, which evolved as network of networks was awarded an EU grant in autumn 2020 and was called PHIRI (Population Health Information Research Infrastructure). Results Responses from up to 31 countries were compiled and shared immediately via the European Health Information Portal. This exchange was complemented by special REFs that focused on the advantages and disadvantages of vaccination, for example. By July 2023, 54 REFs had taken place with topics going beyond COVID-19. Conclusion The REF demonstrated its value for quick yet evidence-based cross-country exchange in times of crisis and was highly appreciated by countries and European Commission. It demonstrated its sustainability even after the acute crisis by expanding the topics covered and managing to continue exchange with the aim of capacity building and mutual learning, making it a true EU response and coordination mechanism.

Throughout the COVID-19 pandemic, shortages of scarce healthcare resources consistently presented significant moral and practical challenges. While the importance of vaccines as a key pharmaceutical intervention to stem pandemic scarcity was widely publicized, a sizable proportion of the population chose not to vaccinate. In response, some have defended the use of vaccination status as a criterion for the allocation of scarce medical resources. In this paper, we critically interpret this burgeoning literature, and describe a framework for thinking about vaccine-sensitive resource allocation using the values of responsibility, reciprocity, and justice. Although our aim here is not to defend a single view of vaccine-sensitive resource allocation, we believe that attending critically with the diversity of arguments in favor (and against) vaccine-sensitivity reveals a number of questions that a vaccine-sensitive approach to allocation should answer in future pandemics.

Background: More than 20 million children in the United States lack access to primary health care. Practice Learning: Research shows that students with regular access to physical and mental health services have fewer absences, are more social, less likely to participate in risky behaviors, have improved focus and higher test scores. Implication For School Health Policy, Practice, And Equity: School‐based health centers (SBHCs) can be an important, valuable and viable health care delivery option to meet the full‐range of primary health care needs of students where they spend the majority of their wake hours, ie, in school. Children in rural and other underserved communities, as well as those underinsured, non‐insured, economically challenged, underserved, and the most vulnerable among us are especially at risk. Conclusions: This paper discusses the history, value, and importance of SBHCs from myriad perspectives, including physical and emotional wellbeing, academic and social success, and the promotion of a positive transition to adulthood. In addition, the authors' experiences that resulted in building the first SBHC in the Mid‐Hudson Valley Region of New York State are shared. These experiences form the foundation for creating an important roadmap for individuals and school leaders that are interested in bringing a SBHC to their school and district. [ABSTRACT FROM AUTHOR]

A vaccine for coccidioidomycosis is likely to undergo trials in the near future. In this paper, we raise 4 questions that should be answered before its use and offer our solutions to these questions.

The knowledge base in the field of vaccination research and development has greatly improved. In the present era, utilizing a novel vaccine design and optimization strategy improves the vaccination efficiency and activity. In this regard, a novel drug delivery system produces nanosized, vaccine-loaded carrier molecules, which is called Nanovaccine. The advancement in nanovaccine and improved technology comes under preclinical and clinical trials, whereas different routes of administration strategy are applied against infectious diseases. The nanovaccine has high efficiency and immunogenicity compared to the traditional vaccine. Its long-lasting effect reduces the booster dose as well. One of the factors like routes of administration affects the efficiency of nanovaccine. The parenteral and mucosal vaccination is a traditional administration approach. In order to increase the safety and effectiveness of vaccines, innovative administration methods such as needless injection and polymeric formulations are now being developed. The presented paper shows a mechanism involved in nanovaccine delivery, and a method of administration via a different route, to learn more about their possible effects on immunogenicity, effectiveness, safety, sustained release and dose frequency reduction. The various advanced vaccine delivery methods, with special emphasis on its industrial and regulatory requirements for the higher production of nanovaccine, are also discussed. Illustrations of nanovaccine delivery systems overcoming barriers such as mucus layer and enzymatic degradation. Diagrams demonstrating the potential benefits of nanovaccines in enhancing immune response and providing targeted protection against pathogens. [ABSTRACT FROM AUTHOR]

Immunization programs globally have played a pivotal role in reducing mortality rates. However, the effectiveness of these programs often falls short of the intended coverage targets, primarily due to challenges within the supply chain, storage facilities, and distribution processes. Notably, a substantial percentage of vaccine wastage has been observed in numerous countries, thereby imposing a significant financial burden on immunization initiatives, and presenting a formidable challenge to policymakers. This paper undertakes a comprehensive study of the financial dynamics inherent in an immunization program within the context of India. Employing a systems perspective, we scrutinize the intricate interactions among various cost factors. Through a five-year system dynamics simulation, we derive insights into the amplified financial constraints resulting from vaccine wastage and the inefficiencies associated with shared personnel. Furthermore, our analysis extends to evaluate the impact of an additional investment aimed at enhancing the quality of the cold chain infrastructure and health worker proficiency on the overall funds of the immunization program. This research contributes to a nuanced understanding of the financial intricacies of immunization programs, offering valuable insights for policymakers and stakeholders seeking to optimize program efficiency and resource allocation.

• Lack of expertise, integrating policy recommendations, and visibility were challenges. • Collaboration, linkages to policymakers, and effective communication were opportunities. • Optimizing the Regional NITAG Network is one of the most promising ways forward. Following the COVID-19 pandemic, the Americas faced a significant decline in vaccination coverage as well as increased vaccine hesitancy. The objective of this paper is to summarize the challenges and opportunities outlined by the National Immunization Technical Advisory Groups (NITAGs) in Latin America and the Caribbean (LAC) and prioritize targeted interventions. The exploratory survey included open-ended questions on two primary components: challenges, and opportunities. Free-text comments presented by each NITAG were collated and classified using indicators and sub-indicators of the NITAG Maturity Assessment Tool (NMAT). Opportunities were classified thematically, and priority actions were generated from the responses. All 21 NITAGs in LAC, representing 40 countries, 76 % of which have been active for over a decade, responded to the survey. The most common challenges were establishment and composition (62 %), integration into policymaking (62 %), resources and secretariat (52 %), and stakeholder recognition (48 %). The distribution of responses was seen across the whole sample and did not suggest a more pronounced need in relation to year of establishment. Opportunities included maximizing the Regional NITAG Network of the Americas (RNA) to facilitate collaboration, information sharing, visibility, and communication; existing global, regional, and systemic analyses; the World Health Organization/Pan American Health Organization (WHO/PAHO) templates for standard operating procedures; twinning programs with mature NITAGs; and NITAGs in governance structures. Action plans were outlined to formalize the establishment of NITAGs and broaden their composition; strengthen decision-making and access to data resources; and enhance the credibility of evidence-based recommendations and their uptake by policymakers and the public. NITAG challenges are not unique to LAC. NITAGs have outlined a short-term prioritized action plan which is critical to enhancing NITAG value and importance in countries. [ABSTRACT FROM AUTHOR]

• Parents' migration status is associated with infant's timely vaccination. • Having a foreign-born mother is positively associated with infant's timely vaccination. • Having a foreign-born father is positively associated with infant's timely vaccination. • Among migrant population, odds of timely vaccination decreases as length of stay increases. • Future research may explore factors behind lower rates of timely vaccination among settled migrants. Migration has been recognized as an important determinant of child health outcomes including childhood vaccination status. This paper aims to examine the association between parental migration status and a less studied aspect of child immunization outcomes, namely timeliness, within the context of New Zealand (NZ), a country characterized by a substantial proportion of its resident population born overseas. Additionally, the study explored the impact of residential duration on children's immunization timeliness. The data was taken from a large, representative population-based cohort study in NZ (Growing Up in NZ study). A total of 6156 children and their parents, comprising 2241 foreign-born and 3915 NZ-born mothers and a sub-group of their partners were included in the analysis. The survey data was linked with the National Immunization Register dataset. Timely immunization was defined as receiving two vaccines at each scheduled vaccination point (at six-week, three-month, and five-month, totaling six doses of vaccines) within 30 days of their due date. We examined the associations between parental migration status, maternal residential duration, and child immunization timeliness while controlling for socio-economic variations. The results were presented as adjusted odds ratios (AORs) with 95 % confidence intervals (CIs). The findings revealed that after adjustment for socioeconomic differences, children of foreign-born mothers exhibited higher odds of receiving all six studied vaccine doses on time compared to children of native-born mothers (AOR 1.51, 95 %CI:1.27–1.78). Similarly, having a foreign-born father was also significantly associated with timely completion of all six vaccine doses. Children of recent immigrants who had resided in the country for less than five years demonstrated higher odds of timely vaccination of all six vaccine doses compared to children of settled immigrants who had lived in the country for five or more years (AOR 1.65, 95 %CI: 1.25–2.19). This study revealed a significant pattern in NZ where immigrants exhibited higher rates of timely immunization for their children compared to native-born parents. However, the findings also underscore the importance of providing support to settled immigrants, as their children experienced declines in timely vaccination rates compared to children of recent immigrants and even those born to NZ-born parents.

The U.S. Centers for Disease Control and Prevention (CDC) developed and implemented the CDC COVID-19 Vaccine Pregnancy Registry (C19VPR) to monitor vaccine safety. Potential participants who received a COVID-19 vaccine in pregnancy or up to 30 days prior to their pregnancy-associated last menstrual period were eligible to participate in the registry, which monitored health outcomes of participants and their infants through phone interviews and review of available medical records. Data for select outcomes, including birth defects, were reviewed by clinicians. In certain cases, medical records were used to confirm and add detail to participant-reported health conditions. This paper serves as a description of CDC C19VPR protocol. We describe the development and implementation for each data collection aspect of the registry (i.e., participant phone interviews, clinical review, and medical record abstraction), data management, and strengths and limitations. We also describe the demographics and vaccinations received among eligible and enrolled participants. There were 123,609 potential participants 18–54 years of age identified from January 2021 through mid-June 2021; 23,339 were eligible and enrolled into the registry. Among these, 85.3 % consented to medical record review for themselves and/or their infants. Participants were majority non-Hispanic White (79.1 %), residents of urban areas (93.3 %), and 48.3 % were between 30 and 34 years of age. Most participants completed the primary series of vaccination by the end of pregnancy (89.7 %). Many participants were healthcare personnel (44.8 %), possibly due to the phased roll-out of the vaccination program. The registry continues to provide important information about the safety of COVID-19 vaccination among pregnant people, a population with higher risk of poor outcomes from COVID-19 who were not included in pre-authorization clinical trials. Lessons learned from the registry may guide development and implementation of future vaccine safety monitoring efforts for pregnant people and their infants. [ABSTRACT FROM AUTHOR]

This paper focuses on the omnipresent yet analytically almost invisible role of memory and bodily experiences in childhood vaccination. Previous scholarship on the sociocultural aspects of vaccination has primarily focused on the individual and sociodemographic factors underpinning vaccine hesitancy, the role of healthcare professionals and the politicisation or mediatisation of vaccination. Social practices considering vaccination were primarily explored as a matter of the present. Only little consideration was given to the past, individual biographies and sociohistorical temporalities. To complement this body of work, we focus on cognitively-based, embodied and emotionally-experienced memory related to vaccination. Based on a qualitative study of childhood vaccination conducted in Czechia between 2017 and 2019 consisting of ethnographic observations, in-depth interviews and a document review, we identified three interconnected forms of vaccination memory: bio-immune, social-collective and lived experience. Bio-immune memory refers to the body's physical memory, gained to protect itself from diseases. Social-collective memory focuses on socially shared narratives about diseases and vaccination in the past. The memory of lived experience refers to feelings, embodied knowledge and pain. Our findings may inspire further analysis of childhood vaccination in other geographical contexts and amidst the reconfiguration of attitudes and newly established memories following the COVID-19 pandemic.

This paper challenges historically preconceived notions surrounding a minor's ability to make medical decisions, arguing that federal health law should be reformed to allow minors with capacity as young as age 12 to consent to their own Centers for Diseases Control and Prevention (CDC)-approved COVID-19 vaccinations. This proposal aligns with and expands upon current exceptions to limitations on adolescent decision-making. This analysis reviews the historic and current anti-vaccination sentiment, examines legal precedence and rationale, outlines supporting ethical arguments regarding adolescent decision-making, and offers rebuttals to anticipated ethical counterarguments.

Research on vaccines confirms the crucial role media play in framing discourses and mobilizing public support for successful immunization campaigns. What journalists cover on vaccination issues and their diligence in producing stories can influence attitudes to and uptake of vaccines. This paper contributes to emerging discussions on the role of the media in pandemics and in vaccination programs by interrogating the information seeking and verification practices of journalists reporting on COVID-19 vaccines in Ghana. A cross-sectional online survey was conducted among journalists from June to July 2021 through self-administered questionnaires by means of Google forms. The opinions of 300 respondents, randomly drawn from members of the Ghana Journalists' Association, were solicited and a response rate of 73% obtained. Majority of journalists surveyed relied on official health sources for their information on COVID-19 vaccines (61.5%) and were confident the benefits of vaccines outweigh the risks (70%). While journalists relied on a variety of expert sources, social media platforms served as important sources of information also, with respondents stating a preference for Facebook (48.3%), and WhatsApp (44%). Journalists stated they were guided by sound practices such as source credibility and relevance, but betrayed weaknesses in their verification practices with a third of them admitting to sharing unsolicited information from social media. Journalists in Ghana generally display a positive attitude towards COVID-19 vaccines and regularly search for information from official sources to inform their work, thus making them vital allies in overcoming vaccine hesitancy. Laxity in verification practices, however, makes them inadvertent agents of misinformation. [ABSTRACT FROM AUTHOR]

Objective: Governments use vaccination mandates, of different degrees of coerciveness, to encourage or require childhood vaccination. We elicited the views of well‐informed community members on the public acceptability of using childhood vaccination mandates in Australia. Methods: Four community juries were conducted in Canberra, Launceston, Cairns and Melbourne, Australia between 2021 and 2022. We recruited 51 participants from diverse backgrounds, genders and ages through random digit dialling and social media. Two juries were held in metropolitan areas, and two in regional/rural settings. Outcome measures included jury verdicts and reasons in response to structured questions. Results: All juries were concerned about collective protection and individual rights but prioritised the former over the latter. A majority in all juries supported mandates but juries disagreed with respect to the appropriate mandate types. All juries endorsed using the least restrictive or coercive means to encourage vaccination (providing incentives or education, e.g.) before imposing penalties such as financial losses and school exclusions. The overriding view was that it is fairer to place a direct burden on parents rather than children and that mandates should be designed to avoid inequitable impacts on less advantaged groups in society. Many jurors found conscientious objection acceptable as a controlled option for resolute refusers, provided that overall vaccination coverage remains high. Conclusion: This paper gives policymakers access to the reasons that Australians have for supporting or opposing different mandates under conditions of high knowledge, understanding and deliberation regarding policy options. Sustaining high rates of vaccination requires high levels of co‐operation between governments, public health actors and the public. Our findings highlight the importance of considering public values in the design and implementation of vaccination mandates. Patient and Public Involvement: We sought input from individuals who did and did not vaccinate during the study design. The views and perspectives of nonvaccinating parents were presented in the evidence to juries. We deliberately excluded nonvaccinating individuals from participating, as the divisive and often hostile nature of the topic, and their minority status, made it difficult to ensure they would feel safe as members of the jury without overrepresenting their perspective in the sample. Two related projects engaged directly with these parents. [ABSTRACT FROM AUTHOR]

Introduction: Disparities in the uptake of routine and COVID‐19 vaccinations have been observed in migrant populations, and attributed to issues of mistrust, access and low vaccine confidence. Participatory research approaches and behaviour change theory hold the potential for developing tailored vaccination interventions that address these complex barriers in partnership with communities and should be explored further. Methods: This study used a theory‐informed, community‐based participatory research approach to co‐design a culturally tailored behaviour change intervention aimed at increasing COVID‐19 vaccine uptake among Congolese migrants in London, United Kingdom (2021–2022). It was designed and led by a community‐academic partnership in response to unmet needs in the Congolese community as the COVID‐19 pandemic started. Barriers and facilitators to COVID‐19 vaccination, information and communication preferences, and intervention suggestions were explored through qualitative in‐depth interviews with Congolese migrants, thematically analysed, and mapped to the theoretical domains framework (TDF) and the capability, opportunity, motivation, behaviour model to identify target behaviours and strategies to include in interventions. Interventions were co‐designed and tailored in workshops involving Congolese migrants. Results: Thirty‐two Congolese adult migrants (24 (75%) women, mean 14.3 (SD: 7.5) years in the United Kingdom, mean age 52.6 (SD: 11.0) years) took part in in‐depth interviews and 16 (same sample) took part in co‐design workshops. Fourteen barriers and 10 facilitators to COVID‐19 vaccination were identified; most barrier data related to four TDF domains (beliefs about consequences; emotion; social influences and environmental context and resources), and the behavioural diagnosis concluded interventions should target improving psychological capability, reflective and automatic motivations and social opportunities. Strategies included culturally tailored behaviour change techniques based on education, persuasion, modelling, enablement and environmental restructuring, which resulted in a co‐designed intervention comprising community‐led workshops, plays and posters. Findings and interventions were disseminated through a community celebration event. Conclusions: Our study demonstrates how behavioural theory can be applied to co‐designing tailored interventions with underserved migrant communities through a participatory research paradigm to address a range of health issues and inequalities. Future research should build on this empowering approach, with the goal of developing more sensitive vaccination services and interventions which respond to migrant communities' unique cultural needs and realities. Patient or Public Contribution: Patient and public involvement (PPI) were embedded in the participatory study design and approach, with community members co‐producing all stages of the study and co‐authoring this paper. An independent PPI board (St George's Migrant Health Research Group Patient and Public Involvement Advisory Board) comprising five adult migrants with lived experience of accessing healthcare in the United Kingdom were also consulted at significant points over the course of the study.

Amidst the ongoing COVID-19 pandemic, Ghana is currently grappling with simultaneous outbreaks of Marburg virus disease and human monkeypox virus. The coexistence of these outbreaks emphasizes the imperative for a collaborative and global approach to enhance surveillance and expedite case detection. While Ghana has made efforts to respond to these outbreaks, this paper outlines the lessons learned and proposes recommendations in this regard. It is crucial to intensify response efforts at the local, regional, and national levels to effectively contain the spread of these infectious diseases. Therefore, this paper suggests prioritizing the following recommendations as crucial for assisting Ghana in adequately preparing for future outbreaks and safeguarding global public health: strengthening surveillance system through digitization, rapid and effective response; risk communication and community engagement; healthcare system readiness; and research and collaboration. Also, prioritizing building healthy public policies and developing personal skills of health personnel across the country is key for future outbreak response. [ABSTRACT FROM AUTHOR]

Background The issue of reluctance towards vaccination is becoming more worrisome. Health care workers (HCWs) are the primary point of contact with individuals who make decisions about vaccination. Therefore, it is crucial that HCWs receive sufficient training and periodic updates. The main objective of this systematic review is to evaluate the HCWs' training needs in vaccination and vaccine uptake. Methods In February 2022, a search was conducted on MEDLINE, Scopus and Google Scholar databases. The search included papers written in English, Italian, Portuguese, Spanish, French and Romanian, with a publication date ranging from 1 January 2011 to 24 February 2022 and conducted in Europe. To assess the methodological quality of the papers, the Appraisal tool for Cross-Sectional Studies was utilized. Results The search of scientific literature yielded 640 outcomes on PubMed, 556 on Scopus and 15 on Google Scholar, for a total of 1211 records. After eliminating duplicates, screening titles and abstracts and evaluating the full text of the articles, only 25 of them were found suitable for inclusion. The studies' overall quality ranged from moderate to good. The majority of the research emphasized the need for improved knowledge of vaccine-preventable diseases, vaccine efficacy, immunization schedules and vaccine adverse effects. Conclusions It is vital to prioritize educational programmes on vaccinology and vaccine hesitancy for HCWs, with the objective of improving their knowledge, awareness and attitudes. Addressing the diversity of educational backgrounds, roles and training requirements of HCWs involved in vaccination across Europe is a critical issue that must be tackled for future initiatives.

Solidarity between more and less vulnerable groups is fundamental to an effective public health response to a global pandemic. Yet in the case of COVID-19, a focus on deciding who can and who cannot be protected from harm has shaped the pandemic experience and continues to determine the post-pandemic trajectory of life with SARS-CoV-2. In this paper I discuss how this has affected our understanding and acceptance of solidarity. [ABSTRACT FROM AUTHOR]

Although Streptococcus pneumoniae has been one of the most common bacterial causes of disease in humans, its impact has been blunted by the broad use of vaccines. Since 2018, the incidence of invasive pneumococcal disease in Korea decreased with effective pneumococcal vaccines but is on the rise again recently. In this paper I will review the epidemiology, risk factors, and antibiotic resistance of invasive pneumococcal disease after the introduction of the pneumococcal vaccine in Korean adults.

Vaccine mandates can take many forms, and different kinds of mandates can implicate an array of values in diverse ways. It follows that good ethics arguments about particular vaccine mandates will attend to the details of individual policies. Furthermore, attention to particular mandate policies—and to attributes of the communities they aim to govern—can also illuminate which ethics arguments may be more salient in particular contexts. If ethicists want their arguments to make a difference in policy, they should attend to these kinds of empirical considerations. This paper focuses on the most common and contentious vaccine mandate reform in the contemporary United States: the elimination of nonmedical exemptions (NMEs) to school and daycare vaccine mandates. It highlights, in particular, debates about California's Senate Bill 277 (SB277), which was the first successful recent effort to eliminate NMEs in that country. We use media, secondary sources, and original interviews with policymakers and activists to identify and evaluate three ethics arguments offered by critics of SB277: parental freedom, informed consent, and children's rights to care and education. We then turn to one ethics argument often offered by advocates of SB277: harm prevention. We note, however, that three arguments for mandates that are common in the immunization ethics literature—fairness/free‐riding, children's rights to vaccination, and utilitarianism—did not play a role in debates about SB277.

Background To help distinguish vaccine-related adverse events following immunization (AEFI) from coincidental occurrences, active vaccine pharmacovigilance (VP) prospective surveillance programs are needed. From February to May 2021, we assessed the system and facility readiness for implementing active AEFI VP surveillance in Addis Ababa, Ethiopia. Methods Selected hospitals were assessed using a readiness assessment tool with scoring measures. The site assessment was conducted via in-person interviews within the specific departments in each hospital. We evaluated the system readiness with a desk review of AEFI guidelines, Expanded Program for Immunization Guidelines and Ethiopian Food and Drug Administration and Ethiopian Public Health Institute websites. Results Of the hospitals in Addis Ababa, 23.1% met the criteria for our site assessment. During the system readiness assessment, we found that essential components were in place. However, rules, regulations and proclamations pertaining to AEFI surveillance were absent. Based on the tool, the three hospitals (A, B and C) scored 60.6% (94/155), 48.3% (75/155) and 40% (62/155), respectively. Conclusions Only one of three hospitals assessed in our evaluation scored >50% for readiness to implement active AEFI surveillance. We also identified the following areas for improvement to ensure successful implementation: training, making guidelines and reporting forms available and ensuring a system that accommodates paper-based and electronic-based recording systems.

The humanitarian crisis precipitated by the ongoing conflict in Sudan poses profound risks to the health and welfare of the country's children. This paper explores essential policy interventions to safeguard child mental health services under these challenging circumstances. Crucial strategies include enhancing healthcare accessibility for children and their caregivers, promoting education, and improving household living conditions. Additionally, it is vital to provide improved access to information about nutritious food and strengthen health systems in areas directly exposed to conflict. Cooperation with international aid organizations is paramount to delivering medical supplies to functioning health facilities. The paper also recommends partnerships with local non-governmental and humanitarian organizations to execute public health programs effectively. These multi-faceted policy measures underscore the importance of a comprehensive response to ensure the health and well-being of children amid the turmoil in Sudan. Through these strategies, we aim to provide a blueprint for policymakers and humanitarian organizations to mitigate the devastating impacts of the conflict on the country's most vulnerable population.

Healthcare social networks have a significant role in providing connected and personalized healthcare environment with real-time capabilities. However, building resilient, robust and technology-driven healthcare 5.0 has its own barriers. Especially with social media's high susceptibility to rumors and fake news, these networks can harm the society. Many researchers have been investigating the process of information diffusion, and it has been one of the most intriguing issues in network analysis. Modeling rumor propagation is one of the prominent researched topics in recent years. Traditional models assume that rumor propagation happens only in one direction, where only supporters are supposed to be active, whereas, in a real-life situation, both supporters and deniers of the information operate simultaneously. In this paper, we introduce a model for the recovery of nodes in a setting where rumor propagation and rumor control happen simultaneously. We propose the Susceptible-Infected-Recovered-Anti-spreader model based on the notion of spreading of epidemics and also its applications to modeling the propagation of rumors and control of rumor. Our model assumes people have multiple forms of reactions to rumor, either posting it, deleting it or announcing the rumor as fake. This paper also suggests how the model can act as a simulation method to compare two node centrality algorithms where spreaders chosen from one centrality algorithm try to spread the rumor, and the anti-spreaders chosen from other centrality try to dispel the rumor and vice versa. We simulate the proposed algorithm on different weighted and unweighted real-world network datasets and establish that the experimental results agrees with the proposed model. [ABSTRACT FROM AUTHOR]

This article presents the World Health Organization’s (WHO) recommendations on the use of fractional doses of yellow fever vaccines excerpted from the “Yellow fever vaccine: WHO position on the use of fractional doses – June 2017, Addendum to Vaccines and vaccination against yellow fever WHO: Position Paper – June 2013 ″, published in the Weekly Epidemiological Record [1,2] . This addendum to the 2013 position paper pertains specifically to use of fractional dose YF (fYF) vaccination (fractional dose yellow fever vaccination refers to administration of a reduced volume of vaccine dose, which has been reconstituted as usual per manufacturer recommendations) in the context of YF vaccine supply shortages beyond the capacity of the global stockpile. The current WHO position on the use of yellow fever (YF) vaccine is set out in the 2013 WHO position paper on vaccines and vaccination against YF and those recommendations are unchanged. Footnotes to this paper provide a number of core references including references to grading tables that assess the quality of the scientific evidence, and to the evidence-to-recommendation table. In accordance with its mandate to provide guidance to Member States on health policy matters, WHO issues a series of regularly updated position papers on vaccines and combinations of vaccines against diseases that have an international public health impact. These papers are concerned primarily with the use of vaccines in large-scale immunization programmes; they summarize essential background information on diseases and vaccines, and conclude with WHO's current position on the use of vaccines in the global context. Recommendations on the use of Yellow Fever vaccines were discussed by SAGE in October 2016; evidence presented at these meetings can be accessed at: www.who.int/immunization/sage/meetings/2016/October/presentations_background_docs/en/ .
