Resumo
Há poucos dados sistematizados sobre eventos adversos da vacina contra influenza no Brasil. Este trabalho visou identificar estes eventos em população acima de 60 anos que compareceu à Campanha Nacional de Vacinação do Idoso, em Distrito de Campinas, SP, em 2000. Foi realizada entrevista para relato de sintomas gerais e locais, com nexo temporal após a aplicação do imunobiológico, em amostra aleatória sistemática da população (n=206). Registraram-se 20,38% (IC 14,87-25,88) dos indivíduos com um ou mais sintomas, sendo a dor no local da vacina, a mais freqüente 12,6% (IC 8,09-17,15). Ajustou-se um modelo de regressão logística múltipla, tendo como variável dependente, a ocorrência de pelo menos um evento adverso. A variável independente que se mostrou associada às reações adversas foi o sexo (feminino) (OR=5,89 e IC 2,08-16,68). Os achados deste estudo reafirmam a pequena reatogenicidade da vacina contra a influenza.
Adverse reactions associated with vaccines are poorly documented in Brazil. The aim of this article was to identify the incidence of adverse effects to the influenza vaccine in the elderly of Campinas district, SP. A questionnaire was applied to a random systematic sample of people over 60 years of age (n = 206), participating in the Brazilian Vaccination Campaign during 2000. Temporal link was taken into account for general and local symptoms after vaccine. One or more symptoms were reported by 20.48% (CI 14.87-25.88) and local pain was the most frequent complaint 12.62% (CI 8.09 -17.15). A multi-regression logistic model was adjusted, considering any adverse effects after exposure as the dependent variable. The independent variable associated with adverse effects was female gender (OR = 5.89 and CI 2.08-16.68). This study reaffirms the low reactogenicity of influenza vaccine.
