Abstract	ABSTRACT Since March 2020, Brazil has faced the pandemic of the coronavirus disease 2019 (Covid-19), which has severely modified the way in which the population lives and uses health services. As such, face-to-face attendance has dropped dramatically, even for child vaccination, due to measures of social distancing to mitigate the transmission of the virus. Several countries have recorded a substantial drop in vaccination coverage in children, especially of those under two years of age. In Brazil, administrative data indicate the impact of the covid-19 pandemic on this downward trend, which was already an important challenge of the National Immunization Program in recent years. Many children will be susceptible to immunopreventable diseases, which reinforces the need to assess the vaccine status of schoolchildren before returning to face-to-face classes.

Abstract	Resumo A vacinação é um componente essencial da atenção primária à saúde e do enfrentamento de emergências em saúde. No entanto, apesar do progresso ocorrido nas últimas décadas, persistem importantes barreiras que resultam na queda de coberturas e disparidades entre os países no acesso a novas vacinas. Neste cenário, a Organização Mundial da Saúde (OMS) lançou, em 2020, a Agenda de Imunização para o decênio 2021-2030 (AI2030). Este artigo tem o objetivo de debater os principais fatores que afetam o acesso às vacinas e as estratégias para promoção da equidade no acesso a elas a nível global e nacional. Tais fatores são multisetoriais e precisam ser considerados em ambos os níveis, destacando-se as barreiras financeiras e geográficas, os desafios de infraestrutura, fatores socioeconômicos e culturais, políticas públicas e governança. O texto aponta a necessidade de remodelação da arquitetura global das cadeias produtivas e dos centros de pesquisa e inovação, criando e/ou fortalecendo as existentes em países de baixa e média renda. Além disso, é necessário estabelecer novos mecanismos e modelos de produção e comercialização de vacinas. As estratégias adotadas para acesso a vacinas e outras tecnologias em saúde estão no centro do debate da agenda de saúde global.

Abstract	ABSTRACT 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.

Abstract	This study aimed to estimate the prevalence of non-vaccination and the reasons for nonadherence to the influenza vaccine among older Brazilians according to sociodemographic characteristics. A cross-sectional study was conducted with data from older people (≥ 60 years of age; n = 23,815) who participated in the 2013 National Health Survey. Frequencies of non-vaccination and the main reasons for nonadherence were calculated with respective 95% confidence intervals. The prevalence of non-vaccination was 26.9% (approximately 7,106,730 older people). The reason rarely gets the flu was the most cited among the men (28.2%), the 60-to-69-year-old age group (29.6%), individuals with higher education (41.9%), and those with health insurance (32.3%). Fear of a reaction was the most cited reason in the northeastern region (25.4%), among women (29.3%), longer-lived individuals (≥70 years; 28.7%), and those who did not know how to read/write (26.7%). A total of 12.1% reported not believing in the vaccine’s protection, and 5.5% did not know that it was necessary to take vaccine. The proportions of the main reasons for non-vaccination varied by sociodemographic characteristics. This study’s findings highlight the need to increase older people’s knowledge regarding influenza and influenza vaccines. Healthcare providers should be encouraged to counsel older people–especially those in subgroups with lower adherence, such as residents in the Northeast region, those aged 60–69 years, those who do not know how to read/write, those without a spouse/companion, and those without health insurance–regarding the different aspects of the vaccine and formally indicate it for groups at risk.

Abstract	Resumo Objetivo: Descrever o perfil epidemiológico de gestantes com suspeita de infeção pelo vírus Zika, notificadas no Sistema de Vigilância às Emergências em Saúde Pública, do estado de São Paulo, Brasil, seu espectro de anormalidades e/ou resultados da gestação. Métodos: Estudo epidemiológico descritivo de uma coorte de gestantes sintomáticas com suspeita de infecção pelo vírus Zika, residentes no estado de São Paulo, notificadas no período 2015-2018 e o resultado de sua gestação. Resultados: Das 2.329 gestantes estudadas, 29,3% foram confirmadas com a infeção, na quase metade solteiras (44,8%), a maioria de raça/cor da pele branca (74,2%), com ensino médio completo (53,6%), e concentradas no nordeste do estado. A proporção de recém-nascidos com anomalias do sistema nervoso central foi de aproximadamente 4,0%. Conclusão: Os resultados encontrados caracterizam a transmissão do vírus Zika em São Paulo e podem subsidiar ações de saúde pública nos locais com maior risco de transmissão da doença.

Abstract	The scope and coverage of the Brazilian Immunization Program can be compared with those in developed countries because it provides a large number of vaccines and has a considerable coverage. The increasing complexity of the program brings challenges regarding its development, high coverage levels, access equality, and safety. The Immunization Information System, with nominal data, is an innovative tool that can more accurately monitor these indicators and allows the evaluation of the impact of new vaccination strategies. The main difficulties for such a system are in its implementation process, training of professionals, mastering its use, its constant maintenance needs and ensuring the information contained remain confidential. Therefore, encouraging the development of this tool should be part of public health policies and should also be involved in the three spheres of government as well as the public and private vaccination services.

Abstract	ABSTRACT OBJECTIVE To estimate the public-private composition of HIV care in Brazil and the organizational profile of the extensive network of public healthcare facilities. METHODS Data from the Qualiaids-BR Cohort were used, which gathers data from national systems of clinical and laboratory information on people aged 15 years or older with the first dispensation of antiretroviral therapy between 2015–2018, and information from SUS healthcare facilities for clinical-laboratory follow-up of HIV, produced by the Qualiaids survey. The follow-up system was defined by the number of viral load tests requested by any SUS healthcare facility: follow-up in the private system – no record; follow-up at SUS – two or more records; undefined follow-up – one record. SUS healthcare facilities were characterized as outpatient clinics, primary care and prison system, according to the respondents’ self-classification in the Qualiaids survey (72.9%); for non-respondents (27.1%) the classification was based on the terms present in the names of the healthcare facilities. RESULTS During the period, 238,599 people aged 15 years or older started antiretroviral therapy in Brazil, of which 69% were followed-up at SUS, 21.7% in the private system and 9.3% had an undefined system. Among those followed-up at SUS, 93.4% received care in outpatient clinics, 5% in primary care facilities and 1% in the prison system. CONCLUSION In Brazil, antiretroviral treatment is provided exclusively by SUS, which is also responsible for clinical and laboratory follow-up for most people in outpatient clinics. The study was only possible because SUS maintains records and public information about HIV care. There is no data available for the private system.

Abstract	This study aims to evaluate maternal vaccine hesitancy and its associated factors. This is a cross-sectional study of a probabilistic sample of 450 mothers of children born in 2015, living in a Brazilian city, and who was, at the time of data collection, more than two years old. We used the tool proposed by the World Health Organization (10-item Vaccine Hesitancy Scale). To assess its structure, we performed, exploratory and confirmatory factor analyses. We performed linear regression models to evaluate the factors associated with vaccine hesitancy. The factor analysis showed two components for the vaccine hesitancy scale: lack of confidence in vaccines and risk perception of vaccines. High family income was associated with lower vaccine hesitancy (greater confidence in vaccines and lower risk perception of vaccines), while the presence of other children, regardless of birth order, in the family was associated with lower confidence in vaccines. A good rapport with health professionals, willingness to wait for the vaccination and the getting vaccinated through campaigns were associated with greater confidence in vaccines. The deliberate delay or decision not to vaccinate their children and previous experience with adverse reactions to the vaccine were associated with lower confidence in vaccines and greater risk perception of vaccines. Health care providers, especially nurses, play a relevant role to address vaccine hesitancy, guiding vaccination through a trustworthy rapport.
