Concerns remain regarding the rare cardiovascular adverse events, myocarditis and pericarditis (myo/pericarditis), particularly in younger individuals following mRNA COVID-19 vaccination. Our study aimed to comprehensively assess potential safety signals related to these cardiac events following the primary and booster doses, with a specific focus on younger populations, including children as young as 6 months of age. Using the Vaccine Adverse Events Reporting System (VAERS), the United States national passive surveillance system, we conducted a retrospective pharmacovigilance study analyzing spontaneous reports of myo/pericarditis. We employed both frequentist and Bayesian methods and conducted subgroup analyses by age, sex, and vaccine dose. We observed a higher reporting rate of myo/pericarditis following the primary vaccine series, particularly in males and mainly after the second dose. However, booster doses demonstrated a lower number of reported cases, with no significant signals detected after the fourth or fifth doses. In children and young adults, we observed notable age and sex differences in the reporting of myo/pericarditis cases. Males in the 12–17 and 18–24-year-old age groups had the highest number of cases, with significant signals for both males and females after the second dose. We also identified an increased reporting for a spectrum of cardiovascular symptoms such as chest pain and dyspnea, which increased with age, and were reported more frequently than myo/pericarditis. The present study identified signals of myo/pericarditis and related cardiovascular symptoms after mRNA COVID-19 vaccination, especially among children and adolescents. These findings underline the importance for continued vaccine surveillance and the need for further studies to confirm these results and to determine their clinical implications in public health decision-making, especially for younger populations.

Summary: In the early 1980’s concerns about the safety of the whole cell pertussis vaccine in the United States resulted in declining vaccination rates and the withdrawal of multiple vaccine providers from the market. While the possibility of inflammation and febrile reactions to the vaccine were acknowledged by public health authorities, parents also claimed the vaccine was associated with sudden infant death syndrome and encephalopathy. Epidemiological studies examining this question, however, consistently failed to identify an association. We argue that these reactions may have occurred in metabolically vulnerable children, specifically those with defects in fatty acid oxidation. In these children the combination of anorexia and fever that could be caused by the vaccine may have resulted in hypoglycemic episodes and possibly death. We believe that this association was not detected because these conditions were not recognized at the time and because these conditions are uncommon. Nevertheless, at a population level, enough events could have occurred to cause concern amongst parents. [Copyright &y& Elsevier]

The article discusses political issues related to the revised International Health Regulations (IHR). According to the article, the cooperation of regional governments is necessary for the development of centralized approaches to public health. Recognizing the challenges the IHR could pose for federations, the U.S. had requested the insertion of a clause that would acknowledge the unique governance structures of federations.

The article discusses the use of the Web 2.0 in the public health system in the U.S. Web 2.0 is considered as a the second generation in the web services as it manages both the expert and the general public communication of health-related knowledge. The use of the scheme also reflects an evolution of the medical counterculture movements.

The author emphasizes the importance of a no-fault compensation system to protect vaccine programs and the public in Canada. He explains the factors considered in the U.S. to adopt a no-fault compensation system. He notes that there is no crisis of confidence in vaccines that exist in Canada. He asserts that the system addresses concern among vaccine manufacturers on releasing vaccines in the event of pandemic influenza by providing them with legal protection.

Abstract: Background: The roll out of HPV immunization programs across the United States was hindered by controversy. We tracked the debate in the United States through MySpace, then the most popular social networking site, in order to better understand the public''s reaction to the vaccine. Methods: We searched MySpace for all blog discourse related to HPV immunization. We analyzed each blog according to the overall portrayal of HPV immunization, identified the characteristics of the bloggers, and developed a content analysis to categorize the types of supporting arguments made. Results: 303 blogs met our inclusion criteria. 157 (52%) of the blogs were classified as positive, 129 (43%) as negative, and 17 (6%) were ambivalent toward HPV immunization. Positive blogs generally argued that HPV infection was effective and there were no reasonable alternatives to immunizing. Negative blogs focused on the risks of immunizing and relied heavily on vaccine-critical publications to support their viewpoint. Of the blogs where gender could be identified, 75 (25%) were posted by men and 214 (71%) by women. 60% of blogs posted by men were explicitly critical about HPV immunization versus 36% of women''s blogs. Male bloggers also had larger networks of friends. Conclusions: We describe a novel and promising approach to the surveillance of public opinions and attitudes toward immunization. In our analysis, men were far more likely to hold negative views about HPV immunization than women and disseminate negative messages through larger social networks. Blog analysis is a useful tool for Public health officials to profile vaccine criticism and to design appropriate educational information tailored to respond to alternative media/alternative information actively disseminated via social media tools. Public health officials should examine mechanisms by which to leverage this media to better communicate their message through existing networks and to engage in on-going dialogue with the public.

Preterm birth (PTB) is the leading cause of morbidity and mortality in children globally, yet its prevalence has been difficult to accurately estimate due to unreliable methods of gestational age dating, heterogeneity in counting, and insufficient data. The estimated global PTB rate in 2020 was 9.9% (95% confidence interval: 9.1, 11.2), which reflects no significant change from 2010, and 81% of prematurity-related deaths occurred in Africa and Asia. PTB prevalence in the United States in 2021 was 10.5%, yet with concerning racial disparities. Few effective solutions for prematurity prevention have been identified, highlighting the importance of further research., Competing Interests: Disclosure The authors have no disclosures to report., (Copyright © 2024 Elsevier Inc.

This article explores the factors that contributed to the use of different names for H1N1 by diverse actors in the early stages of the pandemic of 2009 and discusses the implications of inconsistent naming practices for the public's understanding of the virus and the credibility of scientists and health authorities. The authors propose a naming protocol for novel variants modeled after the World Meteorological Association's practice for naming weather events, a model that would enable accurate transmission of technical information among experts and provide a stable name for public use, even in the context of incomplete or changing scientific understanding of the nature of the pathogen.

The US Court of Federal Claims, which adjudicates cases for the National Vaccine Injury Compensation Program, has been confronted with more than 5000 cases submitted on behalf of children with autism spectrum disorders, seeking to link the condition to vaccination. Through a test case process, the Omnibus Autism Proceedings have in every instance found no association between autism spectrum disorders and vaccines. However, vaccine advocates have criticized the courts for having an overly permissive evidentiary test for causation and for granting credence to insupportable accusations of vaccine harm. In fact, the courts have functioned as intended and have allowed for a fair hearing of vaccine concerns while maintaining confidence in vaccines and providing protection to vaccine manufacturers.

Practicing evidence-based complementary and alternative medicine (CAM) requires that practitioners develop an ability to understand and appropriately apply the results of published studies addressing questions related to their clinical practice. This paper describes a process by which CAM practitioners can interpret the results of studies evaluating therapeutic interventions and then determine if they can apply these results to their patients. We describe a process for interpreting the results of a study on therapy that involves determining the estimate of the magnitude of the therapy's effect and determining the precision of this estimate. We then describe a process for determining whether the results of a study on therapy can be applied to a given patient that involves determining the extent to which patients in the study differ from the patient being treated and determining if the study addressed all outcomes of interest.

Practicing evidence-based complementary and alternative medicine (CAM) requires practitioners to develop an ability to appraise the quality of published studies addressing questions related to their clinical practice. This paper describes a process by which CAM practitioners can determine the validity of studies evaluating therapeutic interventions. The process requires asking two broad questions: (1). Do the treatment and control group begin with the same prognosis? and (2). Do the treatment and control group remain the same with respect to important prognostic factors? Answering these questions requires determining whether studies used effective randomization, preserved randomization through intention-to-treat analyses, used blinding, and had adequate follow-up of trial participants.

Practicing evidence-based complementary and alternative medicine (EBCAM) requires skills in accessing current valid literature on clinical queries. This requires searching a variety of sources within a broad scope of scientific disciplines. This daunting task requires effective skills for accessing information from both print and electronic sources. This paper identifies the progression from question formulation through to searching and acquiring the valid information. In the evolving information age, complementary and alternative medicine (CAM) practitioners require informational databases and knowledge of search terminology. This paper suggests practical strategies for successful database searches in support of EBCAM.

Complementary and alternative medicine (CAM) education is at a crossroads and has been an area of increasing debate. Public use of CAM has risen dramatically since 1997, with initial reports ranging from 30% to a possible 60% in the United States. Much attention has been directed to the education of the public regarding CAM, with respect to efficacy, potential harm, and integration. Far less attention has been paid to the education of CAM practitioners. In the current climate of integrative health settings, CAM practitioners should be trained to interact with conventional physicians, the public, and policy makers in an evidence-based format. In order to create communication effectively, an evidence-based approach may provide the common ground required for all schools of thought.
