ABSTRACT Objective To characterize the use of private services in infant vaccination and assess vaccination coverage according to the service used. Methods : This was a national vaccination survey conducted in 2020 that estimated the use of private vaccination services and vaccination coverage among infants residing in state capitals and 12 inland municipalities. Results : Of the 37,801 participants, 25.1% (95%CI 23.2;27.2) used private services at least once, with higher proportions in capitals, larger cities and in the South and Southeast regions. Socioeconomic and demographic differences were identified among families, based on the service used. The coverage for the set of vaccines administered up to 24 months was 60.3% (95%CI 58.6;62.0) in the public service and 59.5% (95%CI 55.9;63.0) in private services, and up-to-date vaccines, 10.3% (95%CI 9.1;11.6) and 9.4% (95%CI 7.4;11.8), respectively. Conclusion The use of private services was frequent, with low coverage for the set of vaccines, regardless of the type of service used, especially for up-to-date vaccines.

ABSTRACT Objective To estimate vaccination coverage, identify barriers and hesitancy to vaccinating children up to 24 months, born between 2017-2018, living in the urban area of Rio Branco, Acre, Brazil. Methods Population survey carried out from 2020 to 2021, which assessed sociodemographic characteristics and vaccination status among children. Results Among 451 included children, vaccination coverage was below 80%. Meningococcal C vaccine had the lowest coverage for administered doses (76.3%; 95%CI 70.5;81.3) and doses on time (27.4%; 95%CI 23.1;32.1). The statements “vaccines cause serious adverse reactions” (26.4%; 95%CI 18.1;36.8) and “you don’t need vaccination for diseases that no longer exist” (22%; 95%CI 15.7;29.8) were the most frequent regarding vaccination hesitancy. Lack of vaccines was the main barrier to care (86.6%; 95%CI 71.8;94.3). Conclusion Vaccination coverage in children born in 2017-2018 was below the target recommended for the full schedule of administered doses, both valid and timely administered.

ABSTRACT Objective To analyze full vaccination coverage in live births in 2017 and 2018 in the capitals of the Midwest region of Brazil, according to social strata. Methods Population-based household survey with cluster sampling. Full coverage in children at 12 and 24 months of age and sociodemographic factors were analyzed. Results 5,715 children were analyzed. Full coverage at 12 months of age was 67.9% (95%CI 65.4;70.4), while at 24 months it was 48.2% (95%CI 45.3;51.1). Pneumococcal vaccine had the highest vaccination coverage (91.3%), while the second dose of rotavirus vaccine had the lowest (74.2%). In Campo Grande, no vaccine reached coverage above 90%, with BCG (82.9%) and hepatitis B (82.1%) standing out. Campo Grande and Brasília had the worst vaccination coverage in the high social stratum (24 months of age). Conclusion Vaccination coverage in the Midwest was below 80%, falling short of the recommended target and associated with socioeconomic factors.

ABSTRACT Objective To estimate vaccination coverage and analyze sociodemographic factors associated with non-vaccination in children born in 2017 and 2018 in the state capitals of Northeast Brazil. Methods A household survey using cluster sampling was conducted from 2020-2022 to estimate vaccination coverage and hesitancy. Factors associated with non-vaccination were analyzed using logistic regression to calculate Odds Ratios (OR) and their Confidence Intervals (95%CI). Results Natal was the capital with the lowest vaccination coverage, below 75.0% for most immunizers. Teresina had rates equal to or greater than 90.0% for all vaccines. Among those interviewed, 99.1% (95%CI 98.9;99.3) believe that vaccines are important for health; 95.4% (95%CI 95.0;95.8) trust immunobiologicals and 79.6% (95%CI% 78.8;80.3) are not afraid of reactions. Belonging to the highest socioeconomic stratum (adjusted OR: 1.34 – 95%CI 1.20;1.50) was as a factor associated with non-vaccination. Conclusion Low coverage highlights the need for a better understanding of regional specificities and social inequalities.

ABSTRACT Objective To estimate vaccination coverage in children born between 2017-2018, living in urban areas of state capitals, the Federal District and 12 inland municipalities in Brazil, and to identify associated factors. Methods This was a household survey conducted between 2020-2022, among children up to 24 months old. Vaccination coverage was estimated according to family, maternal and child characteristics. Results Among the 37,801 children in the sample, complete coverage (doses administered) was 60.1% (95%CI 58.6;61.6) and 6.1% (95%CI 5.4;7.0) had not received any vaccines. Coverage was lower among children of mothers with lower level of education (OR = 0.70; 95%CI 0.54;0.90) and in those who experienced delays in receiving any vaccine by 6 months old (OR = 0.28; 95%CI 0.24;0.32). Conclusion Vaccination coverage is below the expected levels. Effective communication strategies are needed to reinforce the importance of routine vaccination, prevent delays and abandonment of the vaccination schedule, in order to recover the high coverage levels achieved in past decades.

ABSTRACT Objective To analyze vaccination coverage according to social strata in children up to 24 months old, living in the municipality of Londrina (PR), Brazil. Methods This was a population-based survey conducted between 2021 and 2022, in which vaccination coverage and sociodemographic aspects of mothers and families were evaluated using Pearson’s chi-square test. Results In a sample of 456 children, complete vaccination coverage varied according to social strata, being 36.0% (95%CI 26.8;57.8); in stratum A; 59.5% (95%CI 26.1;86); in stratum B; 66.2% (95%CI 51.7;78.1); in stratum C; and 70.0% (95%CI 56.1;81.0) in stratum D. Conclusion The analysis of vaccination coverage indicated that social stratum A is at highest risk for vaccine-preventable diseases.

ABSTRACT Objective To estimate hepatitis A vaccination coverage in 24-month-old children and identify factors associated with non-vaccination. Methods This was a survey involving a sample stratified by socioeconomic strata in capital cities (2020-2022), with coverage estimates and 95% confidence intervals (95%CI), the factor analysis was performed using the prevalence ratio (PR) by means of Poisson regression. Results Among 31,001 children, hepatitis A coverage was 88.1% (95%CI 86.8;89.2). Regarding socioeconomic strata (A/B), the variable immigrant parents/guardians was associated with non-vaccination (PR = 1.91; 95%CI 1.09;3.37); in strata C/D, children of Asian race/skin color (PR = 4.69; 95%CI 2.30;9.57), fourth-born child or later (PR = 1.68; 95%CI 1.06;2 .66), not attending daycare/nursery (PR = 1.67; 95%CI 1.24;2.24) and mother with paid work (PR = 1.42; 95%CI 1.16;1.74) were associated with non-vaccination. Conclusion Hepatitis A coverage was below the target (95%), suggesting that specificities of social strata should be taken into consideration.

ABSTRACT Objective To analyze the reliability of records held on the National Immunization Program Information System (SI-PNI) in a subsample of children included in the national vaccination coverage survey in Brazilian state capitals and Federal District in 2020. Methods This was a study of agreement between data recorded on vaccination cards (doses and dates) and on the SI-PNI for 4050 children with full coverage at 24 months. Results Data on 3587 children were held on the SI-PNI, with losses of 11% (95%CI: 10;12). Total agreement between doses and dates in the two sources was 86% (95%CI: 86;87), however taking each dose and vaccine individually, variation was greater, with 32% of data in only one source. Conclusion Part of the information was not recorded, but the discrepancy can be considered small. Nonetheless, underrecording of doses and children can compromise vaccination coverage estimates, altering the numerator and denominator data.

ABSTRACT Objective To evaluate vaccination coverage and delay in vaccine dose administration in infants in six municipalities in the Southern region of Brazil. Methodology National Vaccination Coverage Survey 2020, with infants born alive in 2017 and 2018, carried out from September 2020 to March 2022. Coverage of doses administered, doses administered on time and delay in dose administration were evaluated. Results For 4681 infants analyzed, coverage for vaccines recommended up to 24 months was 68.0% (95%CI 63.9;71.8%) for doses administered and 3.9% (95%CI 2.7%;5.7%) for doses administered on time. Delay time for the majority of late vaccinations was ≤ 3 months. For some boosters, 25% of vaccine administration was delayed by ≥ 6 months. Conclusion In addition to tracking vaccine defaulters, strategies are needed to encourage compliance with the vaccination schedule at the recommended ages.

ABSTRACT Objective To describe vaccination coverage and hesitation for the basic children’s schedule in Belo Horizonte and Sete Lagoas, Minas Gerais state, Brazil. Methods Population-based epidemiological surveys performed from 2020 to 2022, which estimated vaccine coverage by type of immunobiological product and full schedule (valid and ministered doses), according to socioeconomic strata; and reasons for vaccination hesitancy. Results Overall coverage with valid doses and vaccination hesitancy for at least one vaccine were, respectively, 50.2% (95%CI 44.1;56.2) and 1.6% (95%CI 0.9;2.7), in Belo Horizonte (n = 1,866), and 64.9% (95%CI 56.9;72.1) and 1.0% (95%CI 0.3;2.8), in Sete Lagoas (n = 451), with differences between socioeconomic strata. Fear of severe reactions was the main reason for vaccination hesitancy. Conclusion Coverage was identified as being below recommended levels for most vaccines. Disinformation should be combated in order to avoid vaccination hesitancy. There is a pressing need to recover coverages, considering public health service access and socioeconomic disparities.

ABSTRACT Objective To describe timely vaccination completion and obstacles in the first 24 months of life in Brazil, examining associations with maternal race/skin color. Methods Study participants were 37,801 children born in 2017 and 2018 included in the National Immunization Coverage Survey. We calculated prevalence and 95% confidence intervals for timely vaccine completeness and obstacles at 5, 12 and 24 months of life, according to maternal race/skin color. Associations were analyzed using logistic regression. Results 7.2% (95%CI 6.3;8.2) of mothers faced difficulties in taking their children to be vaccinated, and 23.4% (95%CI 21.7;25.1) were not vaccinated when taken. These proportions were 75% (95%CI 1.25;2.45) and 97% (95%CI 1.57;2.48) higher, respectively, among Black mothers. At least one vaccination was delayed among 49.9% (95%CI 47.8;51.9) and 61.1% (95%CI 59.2;63.0) of children by 5 and 12 months, respectively. These rates were higher among Black/mixed race mothers. Conclusion There are racial inequalities in both the obstacles faced and in vaccination rates in Brazil.

Objetivo. Identificar a percepção dos gestores de saúde sobre as ações adotadas e os desafios encontrados no enfrentamento de HIV e sífilis em mulheres venezuelanas migrantes no Brasil. Métodos. Este estudo descritivo-exploratório, de abordagem qualitativa, foi realizado de janeiro a março de 2021 nos municípios de Boa Vista (estado de Roraima) e Manaus (estado do Amazonas). As entrevistas em áudio realizadas com os participantes foram transcritas na íntegra. A análise foi pautada na técnica de avaliação de conteúdo temática. Resultados. Foram entrevistados 10 gestores (cinco em Boa Vista e cinco em Manaus). A análise de conteúdo identificou os seguintes eixos e temas: estrutura disponível para diagnóstico e tratamento de aids e sífilis — acesso, vagas para atendimento/fila de espera, formação das equipes de saúde e suporte psicossocial; desafios enfrentados pelas mulheres venezuelanas — idioma, questões de documentação e frequência de alteração de endereço; e estratégias e ações adotadas e expectativas para o enfrentamento de HIV/aids e sífilis no contexto de migração. Conclusões. Apesar das ações de acolhimento das mulheres venezuelanas migrantes — garantido pela universalidade do sistema de saúde brasileiro — aspectos como o idioma e a falta de documentação permanecem como barreiras. Diante da inexistência de planos de ação e planejamento futuro da atenção a mulheres migrantes portadoras de HIV ou sífilis nos municípios, é importante desenvolver políticas públicas com o objetivo de minimizar as dificuldades enfrentadas por essa população.

Objetivo. Descrever a percepção de mulheres venezuelanas sobre o acesso aos serviços de saúde, ao diagnóstico e ao tratamento de HIV/aids e sífilis no Brasil. Métodos. Trata-se de um estudo descritivo e exploratório, com abordagem qualitativa, realizado no período de fevereiro a maio de 2021 nos municípios de Manaus, estado do Amazonas, e Boa Vista, estado de Roraima. As entrevistas com as participantes foram transcritas na íntegra, com levantamento de temas a partir de análise de conteúdo. Resultados. Foram entrevistadas 40 mulheres (20 em Manaus e 20 em Boa Vista).

Conclusão. Os resultados mostraram a necessidade de elaborar estratégias para mitigar as dificuldades enfrentadas pelas mulheres migrantes da Venezuela residentes no Brasil quanto ao diagnóstico e tratamento de HIV/aids e sífilis, indo além do amparo à saúde garantido pela lei.

Resumo Objetivo: Estimar a prevalência de infecção por SARS-CoV-2 entre trabalhadores do sistema prisional do Espírito Santo, Brasil, no período agosto-setembro de 2020. Métodos: Inquérito em amostra estratificada, mediante entrevistas e testes sorológicos para SARS-CoV-2. Resultados: Nos 986 pesquisados, a prevalência sorológica de infecção por SARS-CoV-2 foi de 11,9% (IC95% 8,1%;15,7%) nos profissionais de saúde, e de 22,1% (IC95% 18,8%;25,3%) nos agentes penitenciários. A positividade foi mais frequente nos profissionais da saúde do norte do estado (19,7%) e em agentes penitenciários do sexo masculino (24,0%). Entre soropositivos, a fadiga foi o sintoma mais frequente nos agentes penitenciários (13,4%), e a mialgia, nos profissionais de saúde (10,8%); e as comorbidades mais prevalentes entre os positivos foram asma ou bronquite (16,2%), para profissionais de saúde, e hipertensão para agentes penitenciários (12,8%). Conclusão: A prevalência sorológica de SARS-Cov-2 foi maior nos agentes penitenciários, achado que deve subsidiar ações de controle e prevenção da doença nesse cenário.

Background The provision of care and monitoring of health are essential for indigenous Venezuelans from the Warao ethnic group, who are at risk of decimation. Objective Analyze a Local Action Plan (LAP) to promote access to the health system of indigenous Venezuelans from the Warao ethnic group (IVWEG) in Manaus, Brazil. Method A mixed-methods study was performed. Quantitative data were collected to assess the provision of care and monitoring of health conditions in IVWEG through a survey that was self-completed by healthcare providers. Qualitative narrative data were collected to gain insight into IVWEG that seek care. We applied descriptive statistics, grouping analysis (GA) by hierarchical levels, and multiple correspondence analysis (MCA). Content analysis was applied to qualitative data. Results 106 healthcare providers participated in the study, with the following characteristics: 94 (88.7%) females, 67 (63.2%) pardo race/color, 40 (37.7%) working in primary healthcare, and 49 (46.2%) nurses. In addition, 43 (40.6%) of the healthcare providers reported providing care to IVWEG. Among the providers, 89 (84%) had received training for assisting IVWEG. Additionally, 30 IVWEG were enrolled for interviews in the qualitative phase. The barriers to seeking care were language, distance to health units, and lack of money for transportation. The LAP proved to facilitate access to the health system by indigenous Venezuelans from the Warao ethnic group in Manaus. The study contributed to knowledge on a LAP addressed to IVWEG and helped improved their access to the health system, providing appropriate training for healthcare providers and other relevant actors by implementing a coherent and consistent public health policy at the local level.
