Análise da situação vacinal da COVID-19: conhecimento, atitudes e práticas de enfermeiros da atenção primária

Abstract

This quantitative, cross-sectional, observational, descriptive, and correlational study examined the COVID-19 vaccination status of Primary Health Care nurses in Uberlândia, Minas Gerais, Brazil. The study aimed to analyze the relationship between nurses knowledge, attitudes, and practices and their vaccination adherence, as well as to describe their sociodemographic characteristics. Data were collected from the municipal immunization information system and from structured questionnaires administered to participating nurses. Findings indicated good levels of vaccine-related knowledge, protocol-based attitudes, and a predominance of proactive educational actions, including the use of digital tools for outreach and follow-up. However, discrepancies between self-reported and officially recorded vaccinations were identified, which were attributed to structural limitations of information systems and behavioral factors such as recall bias, divergent interpretations of complete vaccination, and elements of hesitancy. These results underscore the need for ongoing professional education, institutional support, and improved information systems, as well as the expansion of community-based strategies to strengthen trust and enhance vaccination coverage.
