Abstract
in English, Portuguese

Objective: This study aimed to evaluate the effectiveness of vaccine education on vaccine attitudes and knowledge among nursing students.

Method: This research, designed as a quasi-experimental study, was conducted with 68 participants. Vaccine education was delivered in three sessions at one-week intervals. Data were collected using the Personal Characteristics Scale, the Public Attitudes Toward Vaccination Scale Health Belief Model, and the Vaccine Knowledge Test. Data analysis included frequency, percentage, paired t-tests, and effect size (d) to assess differences between means.

Results: Among the participants, 65.2% were female, 14.5% reported difficulties in accessing healthcare services, and only 8.7% followed official websites for vaccine-related information. The study found that vaccine-related knowledge significantly increased after the intervention, with a large effect size (d: 1.755). Vaccine attitudes also showed moderate changes in effect size across various dimensions: perceived susceptibility (d: 0.666), perceived severity (d: 0.682), perceived benefits (d: 0.760), perceived barriers (d: 0.753), and health motivation (d: 0.395). Additionally, the proportion of participants expressing trust in vaccines increased after the educational sessions.

Conclusion: The findings suggest that vaccine education can contribute to improving vaccine attitudes and knowledge among nursing students. Considering the critical role of nursing students as future stakeholders in healthcare delivery, planning and increasing interventions aimed at enhancing their vaccine attitudes and knowledge is essential.

Objetivo:: Este estudo teve como objetivo avaliar a eficácia da educação sobre vacinas nas atitudes e no conhecimento sobre vacinas entre estudantes de enfermagem.

Método:: Esta pesquisa, delineada como um estudo quase experimental, foi conduzida com 68 participantes. A educação sobre vacinas foi realizada em três sessões com intervalos de uma semana. Os dados foram coletados por meio da Escala de Características Pessoais, da Escala de Atitudes Públicas em Relação à Vacinação - Modelo de Crenças em Saúde e do Teste de Conhecimento sobre Vacinas. A análise dos dados incluiu frequência, porcentagem, testes t pareados e tamanho do efeito (d) para avaliar as diferenças entre as médias.

Resultados:: Entre os participantes, 65,2% eram do sexo feminino, 14,5% relataram dificuldades de acesso aos serviços de saúde e apenas 8,7% acessavam sites oficiais para obter informações relacionadas às vacinas. O estudo constatou que o conhecimento sobre vacinas aumentou significativamente após a intervenção, com um grande tamanho do efeito (d: 1,755). As atitudes em relação à vacina também apresentaram alterações moderadas no tamanho do efeito em várias dimensões: suscetibilidade percebida (d: 0,666), gravidade percebida (d: 0,682), benefícios percebidos (d: 0,760), barreiras percebidas (d: 0,753) e motivação para a saúde (d: 0,395). Além disso, a proporção de participantes que expressaram confiança nas vacinas aumentou após as sessões educativas.

Conclusão:: Os resultados sugerem que a educação sobre vacinas pode contribuir para a melhoria das atitudes e do conhecimento sobre vacinas entre estudantes de enfermagem. Considerando o papel crítico dos estudantes de enfermagem como futuros interessados na prestação de cuidados de saúde, é essencial planejar e intensificar intervenções que visem aprimorar suas atitudes e conhecimentos sobre vacinas.
