Descriptive analytical study on scientific production on the vaccination coverage of adolescents in Brazil, using the integrative review method through research in the Pubmed Central, LILACS (Latin American and Caribbean Literature in Health Sciences) and ADOLEC databases. The selected sample was 07 articles, which were inferred quali and quantitatively. As a conclusion, it was obtained that there is satisfactory vaccination coverage for adolescents aged 10 to 14 years and reduced percentage for adolescents aged 15 to 19 years. It is concluded that there is a gap in the CV of adolescents due to misinformation or the strategies used by the PNI (National Immunization Program), in this range are not contextualized for this public, and there is a need for deepening effective strategies for the 15 to 19 year old age group.

Brazil has the National Immunization Program for disease prevention that offers nineteen vaccines, yet it is known that vaccination coverage according to age is not always reached. Thus, this study aimed to evaluate the vaccination coverage in the municipality of Sinop, in the Mato Grosso state and in the Brazil for meningococcal C conjugate vaccines and Hepatitis B in the period from 2015 to 2019. Method: This is a descriptive, retrospective and cross-sectional study, with data available in the Information System of the National Immunization Program. Results: Vaccination coverage for mingococcal C in children under one year in Sinop was above the target in 2015 and 2018, Mato Grosso was above only in 2015, for the booster dose only Sinop was above the target in 2016. Coverage for hepatitis B in children under 30 days of life demonstrated that Sinop had coverage above the state of Mato Grosso, which in turn was above Brazil. For children under 1 year old, only in 2016 and 2019 the state presented greater vaccination coverage at the expense of Sinop and Brazil. Conclusion: The results demonstrate that there is hesitation on the part of the population regarding vaccination, being greater in vaccines such as meningococcal C. Strengthening childcare is the key to improving the panorama of vaccine coverage.

Over Time

The successful Programa Nacional de Imunizações do Brasil (Brazilian National Immunization Program) has been experiencing a major challenge with regard to vaccination coverage for children, which has been dropping. Several aspects are related, but certainly vaccine hesitancy has been strengthening itself as one of the main concerns of Brazilian public administrators and researchers. Vaccine hesitancy is the delay in acceptance or refusal despite having the recommended vaccines available in health services, being a phenomenon that varies over time, over location and over types of vaccines. Hesitant individuals are between the two poles of total acceptance and refusal of vaccination. Vaccine hesitancy is nothing new in European and North-American countries, and even in Brazil, it has been studied even if under another name. The drop of vaccination coverage observed from 2016 on reiterates the relevance of the theme, which must be better understood through scientific research.

The Impact

The vaccines developed in 2020-2021 against the SARS-CoV-2 virus were designed to prevent severity and deaths due to COVID-19. However, how effective this vaccination campaign was at saving lives remains a methodological challenge. In this work, we developed a Bayesian statistical model to estimate the number of deaths and hospitalizations in individuals above 60 years old in Brazil. Using the actual number of hospitalized and deaths from the Brazilian database, and also the coverage of second dose according to the National Immunization Program, we rebuilt the realized scenario as well as the hypothetical scenario without vaccination in Brazil in order to perform a counterfactual analysis. By computing the difference between the hypothetical and realized scenarios, we were able to estimate the direct effect of COVID-19 vaccination in Brazil. We also evaluated two other hypothetical, but not impossible, scenarios considering earlier vaccination roll-outs. We estimated that more than 165 thousand of 60+ years old individuals were not hospitalized due to COVID-19 until August 28, 2021, and other approximately 100 thousand individuals could not have been hospitalized if the immunization started as soon it was approved in Brazil. We also estimate that more than 75 thousand lives were saved in the period analysed for the same age group, and additional 48 thousand lives could have been saved if the Brazilian Government started the immunization 8 weeks earlier.

O Sarampo é uma doença infectocontagiosa com grande importância clínica, sendo a vacinação a forma mais eficaz de prevenção e é assegurada, no Brasil, pelo Programa Nacional de Imunizações (PNI). Contudo, nos últimos anos, houve reemergência de casos de sarampo. Nesse contexto, o trabalho em questão visa analisar a cobertura vacinal contra sarampo, no Pará, no período de 2010 a 2019, e relacionar com o ressurgimento de casos da doença no estado. Trata-se de um estudo observacional do tipo transversal realizado com dados obtidos por meio do Sistema de Informação do Programa Nacional de Imunizações (SI-PNI) e de Boletins Epidemiológicos publicados pelo Ministério da Saúde (MS). Observou-se que as maiores taxas de cobertura vacinal, no Pará, ocorreram nos anos de 2010 (110,95%) a 2014 (115,73%); houve o decréscimo para 69,29%, em 2015 e, até 2019, não se alcançou a meta preconizada pelo MS de 95% de cobertura. Nesse contexto, foram confirmados 41 casos de sarampo no Estado, tornando-o o 6° estado com maior número de casos confirmados dentre os estados analisados. Desta forma, apontam-se fatores que associam o surgimento de casos novos com a diminuição da cobertura, tal qual a hesitação vacinal, alertando que o programa de vacinação deve ser fortalecido para que doenças não retornem ao meio social. ABSTRACTMeasles is an infectious disease of great clinical significance, being vaccination the most effective form of prevention, ensured by the National Immunization Program (Programa Nacional de Imunização – PNI), in Brazil. However, in recent years, there has been reemergence of measles cases. In this context, this study aims to analyze measles vaccination coverage in the State of Pará from 2010 to 2019 and relate it to the resurgence of disease cases in the state. This is an observational cross-sectional study conducted with data obtained through the Information System of the National Immunization Program (Sistema de Informação do Programa Nacional de Imunizações – SI-PNI) and Epidemiological Bulletins published by the Ministry of Health (Ministério da Saúde – MS). It was observed that highest vaccination coverage rates occurred in the years 2010 (110.95%) to 2014 (115.73%), there was a decrease to 69.29%, in 2015, and until 2019, it did not reach the goal recommended by the MS, which is 95% coverage. In this context, 41 measles cases were confirmed in state, making it the 6th state with the highest number of confirmed cases among the analyzed states. Thus, factors that link the emergence of new cases with decreased coverage are pointed out, such as vaccination hesitation, showing that strengthening the vaccination program is necessary, so that diseases do not return to the social environment.Keywords: Measles; Vaccination coverage; Immunization. RESUMENEl sarampión es una enfermedad infecciosa de gran importancia clínica, siendo la vacunación una forma de prevención más eficaz y asegurada, en Brasil, por el Programa Nacional de Inmunizaciones (PNI). Sin embargo, en los últimos años ha habido un resurgimiento de casos de sarampión. En este contexto, el trabajo en cuestión tiene como objetivo analizar la cobertura de vacunación contra el sarampión, en Pará, en el período de 2010 a 2019, y relacionarla con el resurgimiento de casos de la enfermedad en el estado. Se trata de un estudio observacional, transversal realizado con datos recolectados a través del Sistema de Información del Programa Nacional de Inmunizaciones (SI-PNI) y de los Boletines Epidemiológicos publicados por el Ministerio de Salud (MS). Se observó que las mayores tasas de cobertura de vacunación, en Pará, ocurrieron en los años 2010 (110,95%) a 2014 (115,73%); hubo una disminución a 69,29% en 2015 y, hasta 2019, no se alcanzó la meta recomendada por el Ministerio de Salud de cobertura del 95%. En este contexto, se confirmaron 41 casos de sarampión en el estado, lo que lo convierte en el sexto estado con el mayor número de casos confirmados dentro de los estados moldeados. Así, se señalan factores que asocian la aparición de nuevos casos con la disminución de coberturas, como la vacilación vacunal, advirtiendo que se debe fortalecer el programa de vacunación para que las enfermedades no regresen al ámbito social.Palabras clave: Sarampión; Cobertura de vacunación; Inmunización.
