0230/2024 - Prevalência de vacinação contra influenza antes e durante a pandemia de Covid-19 em um município do Sul do Brasil: estudos de base populacional Prevalence of influenza vaccine before and during the Covid-19 pandemic in a city in Southern Brazil: population-based studies
Este estudo objetivou avaliar a prevalência da vacinação contra a influenza antes e durante a pandemia e seus fatores associados na população adulta e idosa de um município do sul do Brasil. Trata-se de um estudo transversal realizado com dados de duas pesquisas de base populacional realizadas em Criciúma-SC. A amostragem foi realizada em duas etapas: seleção aleatória dos setores censitários e dos domicílios. Foram avaliadas as prevalências de vacinação contra influenza antes e durante a pandemia de Covid-19, além de variáveis sociodemográficas, de saúde e comportamentais. Foram estudados 820 indivíduos antes da pandemia e 863 durante a pandemia. A maioria era do sexo feminino, de cor da pele branca e sem plano de saúde. A prevalência de vacinação contra influenza reduziu 18% na pandemia (59,7% vs 49,0%). Antes da pandemia, maior percentual de vacinação foi observad o nos idosos. Durante a pandemia, além dos indivíduos idosos, naqueles que apresentavam multimorbidade e que tinham plano de saúde, a prevalência também foi maior. Observou-se uma queda importante na prevalência de vacinação contra influenza durante a pandemia de Covid-19. Os achados reforçam a necessidade de desenvolver estratégias de saúde pública, como forma de aumentar as coberturas vacinais contra a influenza.

Abstract:
This study aimed to evaluate the prevalence of influenza vaccination before and during the Covid-19 pandemic as well as its associated factors in the adult and elderly population in a city in southern Brazil. This is a cross-sectional study conducted with datatwo populationbased surveys carried out in Criciúma-SC. The sampling process was carried out in two stages: random ion of census tracts and households. We analyzed the prevalence of influenza vaccination coverage before and during the Covid-19 pandemic, as well as sociodemographic, health, and behavioral variables. A total of 820 individuals before the pandemic and 863 during the pandemic were studied. Most of them were female, white skin color and had no health insurance. The prevalence of influenza vaccination reduced by 18% during the pandemic (59.7% vs. 49.0%). Before the pandemic, higher percentage of vaccination was observed in the elderly people. During the pandemic, besides elderly individuals, those with multimorbidity and who had health insurance also showed a higher prevalence. It was observed a reduction in the influenza vaccination coverage during the Covid-19 pandemic. The findings reinforce the need to develop public health strategies to increase the influenza vaccination coverage.
