“…Other investigations conducted in different Brazilian cities (studies with a smaller number of older participants) report not wanting to receive the vaccine [21,29,30], believing that it will provoke a reaction [21][22][23]31], a lack of counseling from health providers [22], forgetfulness [21,22], "never getting the flu" [29] and not thinking that the vaccine is necessary [22,31] as justifications offered by older people for nonadherence. Studies on influenza vaccination for older people, who are particularly vulnerable to negative outcomes from influenza infection, are becoming increasingly relevant due to the rapid growth of this age group in the Brazilian population [24] and the importance of the vaccine as a public health strategy for the prevention of complications resulting from such infection [12,14].…”

“…The most frequent events are local reactions, such as pain, erythema, swelling. Symptoms similar to those of the flu may also occur, such as malaise, a low fever, respiratory discomfort, cough, and coryza [2,21,[23][24][25][26][27][28][29][30], which can give a false notion that the vaccine causes the flu. According to the study by Santos et al [48], 74% of individuals in a risk group believed that the vaccine produces symptoms similar to those of the flu.…”

“…Complacency, inconvenience in terms of access, and a lack of trust are considered determinants of non-vaccination [4,19,20]. In Brazil, a lack of awareness regarding the benefits of the vaccine, lack of concern with influenza, fear of a reaction, and even the stigma of being considered "elderly" have been the most cited reasons for non-vaccination since the onset of the campaigns [21][22][23].…”

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.

“…A relação entre imunização contra influenza e condições socioeconômicas tem sido um dos pontos controversos na literatura. Estudos realizados no estado de São Paulo apontaram tanto maior cobertura em pessoas com menor escolaridade 10,31 , como ausência de associação entre cobertura e escolaridade 28 . Em outro estudo com idosos ao Sul do Brasil, Neves et al 23 verificaram prevalência de vacinação contra influenza 20% maior naqueles com nível econômico mais alto, sem associação significativa para escolaridade.…”

“…Apesar da efetividade da vacina ser heterogênea [4][5][6] , é orientação da Organização Mundial da Saúde (OMS) 2 e do Ministério da Saúde do Brasil (MS) 7 realizar a vacinação anualmente, priorizando determinados grupos, incluindo os idosos com 60 anos ou mais 8 . Desde 2017, a meta de cobertura vacinal do PNI consiste em atingir 90% desta população-alvo 9 ; entretanto, alguns estudos populacionais realizados no país mostram coberturas inferiores, variando de 70 a 78%, nos últimos 10 anos [10][11][12][13] .…”

Resumo Imunizações de rotina durante pandemias podem ser prejudicadas. Este estudo estimou a cobertura vacinal para influenza em idosos durante a COVID-19 através do EPICOVID-19, inquérito populacional realizado em 133 cidades sentinelas dos 26 estados brasileiros e Distrito Federal. Selecionou-se 25 setores censitários por cidade, amostragem proporcional ao tamanho, dez domicílios por setor e uma pessoa por domicílio, aleatoriamente. O quantitativo de 8.265 idosos (≥ 60 anos) foram entrevistados e responderam se haviam sido vacinados contra gripe em 2020. A cobertura foi 82,3% (IC95% 80,1; 84,2), sem diferenças por sexo, idade ou região. Maiores coberturas ocorreram nos mais ricos (84,7% versus 80,1% nos mais pobres) e nos mais escolarizados (87,3% versus 83,2% nos menos escolarizados). Menor cobertura nos indígenas (56,9% versus coberturas superiores a 80% nos demais grupos étnicos). Houve associação positiva com número de comorbidades entre homens, mas não entre mulheres. A maioria vacinou-se na rede pública (97,5%), sendo a rede privada mais utilizada na região Sul, pelos mais escolarizados e mais ricos. Conclui-se que a cobertura vacinal ficou sete pontos percentuais abaixo da meta governamental (90%), e que desigualdades devem ser revertidas em futuras campanhas.

Background and AimsInfluenza is one of the most widespread respiratory infections and poses a huge burden on health care worldwide. Vaccination is key to preventing and controlling influenza. Influenza vaccine hesitancy is an important reason for the low vaccination rate. In 2019, Vaccine hesitancy was identified as one of the top 10 threats to global health by the World Health Organization. However, there remains a glaring scarcity of bibliometric research in that regard. This study sought to identify research hotspots and future development trends on influenza vaccine hesitation and provide a new perspective and reference for future research.MethodsWe retrieved publications on global influenza vaccine hesitancy from the Web of Science Core Collection database, Scopus, and PubMed databases from inception to 2022. This study used VOSviewer and CiteSpace for visualization analysis.ResultsInfluenza vaccine hesitancy‐related publications increased rapidly from 2012 and peaked in 2022. One hundred and nine countries contributed to influenza vaccine hesitation research, and the United States ranked first with 541 articles and 7161 citations. Vaccines‐Basel was the journal with the largest number of published studies on influenza vaccine hesitations. MacDonald was the most frequently cited author. The most popular research topics on influenza vaccine hesitancy were (1) determinants of influenza vaccination in specific populations, such as healthcare workers, children, pregnant women, and so on; (2) influenza and COVID‐19 vaccine hesitancy during the COVID‐19 pandemic.ConclusionsThe trend in the number of annual publications related to influenza vaccine hesitancy indicating the COVID‐19 pandemic will prompt researchers to increase their attention to influenza vaccine hesitancy. With healthcare workers as the key, reducing vaccine hesitancy and improving vaccine acceptance in high‐risk groups will be the research direction in the next few years.
