RESUMO
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. MAIN RESULTS: Hepatitis A vaccination coverage was 88%. Non-vaccination was greater in children with immigrant guardians (strata A/B); of Asian race/skin color, fourth-born child or later, those not attending daycare/nursery and mother with paid work (C/D strata). IMPLICATIONS FOR SERVICES: The results of this study contributed to the Ministry of Health and Health Departments in monitoring vaccination coverage and identifying factors that may negatively impact hepatitis A vaccination coverage. PERSPECTIVES: Further research is needed on the impact of migration on hepatitis A vaccination and vaccination in general. Health managers should be attentive to the different factors affecting vaccination among social strata.

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. MAIN RESULTS: Vaccination coverage for the set of vaccines recommended up to 24 months was 68.0% and 3.9% for on-time doses. Delay time for some doses exceeded six months in up to 25% of infants with delayed vaccination. IMPLICATIONS FOR SERVICES: Monitoring vaccine administration at the recommended ages is necessary, with the adoption of strategies that reinforce routine vaccination to prevent vaccination delays and abandonment. PERSPECTIVES: Primary care in surveillance and care for infants needs to reinforce actions to ensure timely vaccination. Studies to deepen knowledge of vaccination delay, determinants and strategies for their reduction are necessary.

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. MAIN RESULTS: Subsample of 4,050 children, among those completing the full schedule at 24 months studied in the national survey, 11% had not been recorded on the SI-PNI, 32% had unrecorded doses (doses or dates) and there was 8% disagreement between vaccination cards and SI-PNI records. IMPLICATIONS FOR SERVICES: Recognizing the difficulties faced by the SI-PNI and the discrepancies between sources is essential for adopting initiatives to improve data quality, so as to avoid inaccurate estimates of childhood vaccination coverage. PERSPECTIVES: This study is expected to contribute to improving the quality of records and the usability of data for monitoring vaccination coverage of the immunization program from the local to the national level.

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. MAIN RESULTS: The results of the study showed low full vaccination coverage in children up to 24 months of age in Londrina, being higher in the less financially advantaged social stratum, compared to the most advantaged. IMPLICATIONS FOR SERVICES: The results found can support the qualification of the immunization program and enable, based on planning and ongoing health education, the definition of unique strategies to improve vaccination coverage. PERSPECTIVES: Future perspectives point to the importance of carrying out investigations into the challenges inherent to vaccination, as well as qualitative and quantitative research addressing health professionals to better understand the data.

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. MAIN RESULTS: Vaccination coverage of children up to 4 years old was 50.2% in Belo Horizonte, and 64.9% in Sete Lagoas. Fear of severe reactions and believing that vaccination against eradicated diseases is unnecessary were the main reasons for vaccination hesitancy. IMPLICATIONS FOR SERVICES: Recovery of high vaccination coverage among children, considering public health service access conditions and socioeconomic inequities. Acting on reasons for hesitancy that can assist in targeting actions. PERSPECTIVES: The multifactorial context of vaccination hesitancy demands the development of health education strategies to raise awareness about child immunization.

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. MAIN RESULTS: Marked racial inequalities were found in the obstacles to vaccination of children under 24 months in Brazil and to timely vaccination at 5 months and in the first year of life. IMPLICATIONS FOR SERVICES: Racial inequalities in the occurrence of vaccination shortcomings in health services, in the objective restrictions faced by families in taking their children to vaccination centers and in incomplete vaccination in a timely manner need to be addressed by the Brazilian National Health System. PERSPECTIVES: Equal public policies to address barriers to vaccination and qualification of health services need to be implemented. Studies need to deepen understanding of the structural determinants that lead to racial disparities.

Métodos Inquéritos epidemiológicos de base populacional realizados de 2020 a 2022, para estimar coberturas vacinais por tipo de imunobiológico e esquema completo (doses válidas e aplicadas) segundo estratos socioeconômicos, e os motivos de hesitação vacinal. Resultados A cobertura global com doses válidas e a hesitação vacinal de pelo menos uma vacina foram, respectivamente, de 50,2% (IC95% 44,1;56,2) e 1,6% (IC95% 0,9;2,7), em Belo Horizonte (n = 1.866), e de 64,9% (IC95% 56,9;72,1) e 1,0% (IC95% 0,3;2,8), em Sete Lagoas (n = 451), com diferenças entre os estratos. O receio de reações graves foi o principal motivo de hesitação vacinal. Conclusão Identificou-se coberturas abaixo do preconizado para a maioria das vacinas. A desinformação deve ser combatida, evitando-se a hesitação vacinal. Há necessidade premente de recuperar as coberturas, considerando acesso ao SUS e disparidades socioeconômicas.
RESUMO
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.

RESUMO Objetivo Descrever a completude vacinal em tempo oportuno nos primeiros 24 meses de vida no Brasil e os obstáculos para vacinação, testando-se associações com raça/cor da pele materna. Métodos Fez-se coleta de informações sobre os nascidos em 2017 e 2018, constantes no Inquérito Nacional de Cobertura Vacinal. Foram calculados prevalência e intervalos de confiança de 95% de obstáculos à vacinação e completude vacinal em tempo oportuno aos 5 meses, primeiro e segundo ano, segundo raça/cor da pele materna. Empregou-se regressão logística para análise de associações. Resultados Analisaram-se dados de 37.801 crianças. Do total, 7,2% (IC95% 6,3;8,2) dos responsáveis enfrentaram dificuldades para levar seus filhos para vacinação e 23,4% (IC95% 21,7;25,1) das crianças não foram vacinadas, mesmo sendo levadas. Essas proporções foram 75% (IC95% 1,25;2,45) e 97% (IC95% 1,57;2,48) mais elevadas, respectivamente, entre pretas; e 49,9% (IC95% 47,8;51,9) e 61,1% (IC95% 59,2;63,0) das crianças tiveram atraso em alguma vacina até os 5 meses e o primeiro ano, respectivamente. Tais valores foram maiores entre pardas/pretas. Conclusão Há desigualdades raciais nos obstáculos enfrentados e na vacinação no Brasil.
RESUMO
OBJECTIVE: The national vaccination coverage survey on full vaccination at 12 and 24 months of age was carried out to investigate drops in coverage as of 2016. METHODS: A sample of 37,836 live births from the 2017 or 2018 cohorts living in capital cities, the Federal District, and 12 inner cities with 100 thousand inhabitants were followed for the first 24 months through vaccine record cards. Census tracts stratified according to socioeconomic levels had the same number of children included in each stratum. Coverage for each vaccine, full vaccination at 12 and 24 months and number of doses administered, valid and timely, were calculated. Family, maternal and child factors associated with coverage were surveyed. The reasons for not vaccinating analyzed were: medical contraindications, access difficulties, problems with the program, and vaccine hesitancy. RESULTS: Preliminary results showed that less than 1% of children were not vaccinated, full coverage was less than 75% at all capitals and the Federal District, vaccines requiring more than one dose progressively lost coverage, and there were inequalities among socioeconomic strata, favorable to the highest level in some cities and to the lowest in others. CONCLUSION: There was an actual reduction in full vaccination in all capitals and the Federal District for children born in 2017 and 2018, showing a deteriorating implementation of the National Immunization Program from 2017 to 2019. The survey did not measure the impacts of the COVID-19 pandemic, which may have further reduced vaccination coverage.

Abstract Vaccine hesitancy is a phenomenon with the potential to reduce vaccination coverage rates, as observed with the yellow fever vaccine (YFV), leading to epidemics and the reintroduction of controlled immunopreventable diseases. This study, together with the scientific literature, aims to map the relationship among the lack of information, vaccine safety and adverse events, and vaccine hesitancy concerning YFV. A scoping review was conducted in the Virtual Health Library (VHL), National Library of Medicine (PubMed), SCOPUS, Embase, and Web of Science databases, using controlled (DeCS/MeSH) and uncontrolled descriptors. In this work, we selected eleven articles, published in English, Spanish, and Portuguese, with no time limits, which met the inclusion criteria. False information, inadequate knowledge about the immunizer, lack of time to take a vaccination, acceptance of the vaccine, vaccine safety, and fear of adverse events were related to vaccine hesitancy. This study reinforces the importance of access to adequate information, provides guidance on YFV safety and adverse events, and can aid in the development of public health strategies to mitigate hesitancy.

ABSTRACT Objective to analyze the levels of satisfaction, self-confidence, and self-efficacy in clinical simulations among health undergraduates and professionals. Methods cross-sectional study based on Design Science Research Methodology, with 156 health professionals and 149 health undergraduates who participated in an educational session about personal protective equipment use during the COVID-19 pandemic, mediated by Rapid-Cycle Deliberate Practice. Participants responded to a social and work-related questionnaire and to validated scales. For descriptive analysis of independent samples, Chi-squared test and Student's t were used considering p<0.05 as significant. Results we found generally high satisfaction levels (mean ± standard deviation: 4.72±0.58), self-confidence (4.44±0.78), and self-efficacy (4.03±1.17) for favorable items. There were significant statistical differences in seven items in the scale of satisfaction and self-confidence with learning in students, and in six items of the general self-efficacy scale, with p<0.05. Conclusion undergraduates showed higher means of satisfaction and self-confidence with learning, while professionals had higher means of self-efficacy. These results can collaborate for the continuity of clinical simulation practices, increasing procedural safety and quality. Contributions to practice the results show that the activities had a positive contribution, increasing learning opportunities and practical experiences that reflect on the excellence of the routine.

OBJECTIVE: To analyze the trend of mortality from heart failure in Brazilians aged 50 years and over, within 21 years. METHODS: Ecological study with time series analysis of mortality from heart failure in Brazil, according to regions and Federation Units, in individuals aged 50 years or older in the period from 1998 to 2019. Deaths that had heart failure as the underlying cause (coded as I50 according to the International Classification of Diseases) that occurred during the study period were included in the study. Data were obtained from the Mortality Information System of the Brazilian Ministry of Health. Statistical analyses were performed using the Stata 11.1 program, by estimating the mortality rate due to heart failure per 100 thousand inhabitants. In the trend analysis, the Prais-Winsten regression was used. RESULTS: Between 1998 and 2019, 567,789 deaths from heart failure were recorded in adults aged over 50 years, which corresponds to an average rate of 75.5 per 100 thousand inhabitants. There was a downward trend per sex, regions, and in 23 Federation Units. The highest mortality rates were observed for older ages in all regions of the country. CONCLUSION: The trend in mortality rates from heart failure among Federation Units and Brazilian regions was downward over 21 years. There was an upward trend in mortality from heart failure in the northern region and in the category "other health facilities."

RESUMO
Introdução - O estado de portador assintomático ocorre quando o hospedeiro alberga o agente etiológico sem apresentar doença. Os fatores associados ao estado de portador de Neisseria não patogênica (NNP) e Neisseria meningitidis (Nm) diferem entre si, no entanto, as características epidemiológicas de ambas ainda são pouco exploradas. Objetivos - Estimar a prevalência, analisar possíveis diferenças em distintos estratos sociais, identificar o genótipo das cepas isoladas, assim como, investigar fatores associados ao estado de portador de Nm e de NNP em núcleos familiares residentes em Cuiabá-MT. Método - Estudo transversal de base populacional, desenvolvido de 07/2016 a 07/2017, incluindo todos os moradores de uma amostra probabilística estratificada composta de 243 núcleos familiares (domicílios) de área urbana, em bairros de alta e baixa renda do município de Cuiabá. Foram incluídos os domicílios com ao menos uma criança de 12 e 60 meses de idade. Todos os residentes nos domicílios selecionados foram submetidos a coleta de swab de orofaringe para o isolamento de Neisseria spp. Para a comparação de proporções utilizou-se o teste do qui-quadrado. Foram estimadas as razões de prevalências (RP) com seus respectivos intervalos de confiança 95% (IC95%) e para a investigação de fatores associados ao estado de portador de Nm e de NNP foram utilizados modelos de regressão de Poisson. O ajuste das variáveis no modelo final foi avaliado pelo teste de Hosmer e Lemeshow. Resultados: Foram estudados 1.050 indivíduos residentes em 233 núcleos familiares. A prevalência de portadores de Neisseria spp. foi de 10,6% (111/1.050), a de Nm de 2,4% (25/1.050) e de NNP de 8,2% (86/1.050). Dentre 111 portadores, 62 (56,0%) foram por N. lactamica, 25 (22,0%) por Nm, 21 (19,0%) por N. subflava., duas (2,0%) por N. mucosa e uma (1,0%) por N. polysaccharea. Das Nm, 76% (19/25) eram não grupáveis, 16% (4/25) eram do sorogrupo B, 4% (1/25) do sorogrupo C e 4% (1/25) do sorogrupo W. A prevalência de Nm em bairros de baixa renda foi de 2,8% (23/816) e nos de alta renda de 0,8% (2/234) (p=0,058), com uma razão de prevalência (RP) de 3,3 (IC95%:0,8-13,9). A prevalência de NNP em bairros de baixa renda foi de 8,2% (67/816) e em bairros de alta renda de 8,1% (19/234), com uma RP de 1,0 (IC95%:0,6-1,6). Permaneceram independentemente associados ao estado de portador de Nm após ajuste para conviver com tabagista no domicílio e por número de pessoas por dormitório: i) residir em bairro de baixa renda (RPajustada=2,6); ii) faixa etária de 5 a 14 anos (RPajustada=2,7); iii) faixa etária de 15 a 29 anos (RPajustada=2,4) e faixa etária de 30 e anos e mais (RPajustada=1,4). Após o ajuste para a infecção respiratória nos últimos cinco dias, apresentar asma, três ou mais pessoas por dormitório e sexo masculino, mostraram-se independentemente associados ao estado de portador de NNP: i) pertencer a faixa etária de cinco a 14 anos de idade (RPajustada=2,8) e de menores de cinco anos de idade (RPajustada=7,2); ii) residir em casa precária/quitinete (RPajustada=2,1). Conclusões - O contexto social influencia o estado de portador de Nm e NNP. As vacinas conjugadas meningocócicas podem prevenir doenças direta e indiretamente e tais resultados podem subsidiar a elaboração de estratégias de intervenção, especialmente para a identificação de grupos alvo de programas de vacinação
Introduction - The asymptomatic carrier state occurs when the host harbors the etiologic agent without presenting disease. The associated factors with the carrier state of non-pathogenic Neisseria (NNP) and Neisseria meningitidis (Nm) differ among them, however, the epidemiological characteristics of both are still poorly explored. Objectives - To estimate the prevalence, to analyze possible differences in different social strata, to identify the genotype of the isolated strains, as well as to investigate associated factors with the Nm and NNP carrier state in family\'s households living in Cuiabá-MT. Methods - A cross-sectional study was conducted in 07/2016 a 07/2017, in the city of Cuiabá, including all residents of a stratified probabilistic sample which was composed by 243 urban households (families nucleus) with high and low income neighborhoods of the city of Cuiabá. Households with at least one child between 12 and 60 months age were included. All residents in the selected households were submitted to oropharynx swab collection for the isolation of Neisseria spp. To compare proportions the chi-square test was used. For the estimates of prevalence ratios (PR) and the respective 95% confidence intervals (95% CIs), for the analysis of the associated factors with Nm and NNP carrier state Poisson regression models were used. The adjustment of the variables in the final model was evaluated by the Hosmer e Lemeshow test. Results - A total of 1,050 individuals residing in 233 families nucleus were studied. The prevalence of Neisseria spp. was of 10.6% (111/1,050), Nm of 2.4% (25/1,050) and NNP of 8.2% (86/1,050). Among 111 carriers, 62 (56.0%) were by N. lactamica, 25 (22.0%) by Nm, 21 (19.0%) by N. subflava, two (2.0%) by N. mucosa and one (1.0%) by N. polysaccharea. Of the Nm, 76% (19/25) were non-grouping, 16% (4/25) were serogroup B, 4% (1/25) serogroup C and 4% (1/25) serogroup W. Prevalence of Nm in low-income neighborhoods was 2.8% (23/816) and high-income (0.8%) (2/234) (p=0.058), with a prevalence ratio of 3.3 (95% CI:0.8-13.9). The prevalence of NNP in low-income neighborhoods was 8.2% (67/816) and in high-income neighborhoods of 8.1% (19/234), with a PR of 1.0 (95% CI:0,6-1,6). They remained independently associated with Nm state after adjusting to live with a smoker at home and by number of people per dormitory: i) living in a low-income neighborhood (PRadjusted=2.6); ii) age group of 5 to 14 years (PRadjusted=2.7); iii) age range of 15 to 29 years (PRadjusted=2.4) and age group of 30 years and over (PRadjusted=1.4). After adjusting for respiratory infection in the last five days, presenting asthma, three or more people per dormitory and male sex, were independently associated with NNP status: i) belonging to the age group of five to 14 years of age (PRadjusted=2.8) and of children under five years of age (RPadjusted=7.2); ii) residing in a precarious home/kitchenette (PRadjusted= 2.1). Conclusions - The social context influences the carrier state of Nm and NNP. Meningococcal conjugate vaccines can prevent diseases directly and indirectly and such results may support the development of intervention strategies, especially for the identification of target groups of vaccination programs
