Objectives: Use of vaccines is one of the most effective public health interventions against infectious diseases, especially vaccine-preventable pediatric diseases. The aim of our study was to assess the attitudes of Hungarian adults towards vaccinations.

Methods: Self-developed online self-administered questionnaires were completed. After the exclusions, the number of questionnaires processed was 607. Responses were evaluated using IBM SPSS Statistics 24. The results were interpreted using descriptive statistics, χ2 – test and Fischer exact test. Correlation studies were considered significant at level p <0.05.

Results: Influenza vaccination uptake was strongly correlated with age (p< 0.001) and health status (p = 0.034). Evaluating our results, it can be said that the older the respondents, the less the opposition to vaccination (p = 0.011). Respondents who did not, or rarely had side effects during vaccination showed a significantly higher propensity to take influenza vaccination (p = 0.004). Results suggest that the higher the education, the higher the vaccination willingness (p <0.001). Respondents living in cities and counties showed significantly higher opposition to vaccination than those of living in villages (p = 0.016).

Conclusions: Despite the well-documented benefits of vaccination, a large number of adult population is uncertain about vaccination. The role of health workers in increasing the confidence of adult population in vaccinations cannot be neglected, since the involvement of primary care professionals may confirm the authenticity of communication.
