Segmenting attitudes toward vaccination - behavioral insights into influenza vaccination refusal in Romania.

Introduction: Vaccine hesitancy remains a significant public health challenge, particularly in rural populations where geographic and socioeconomic barriers exacerbate the issue. This study aimed to examine the factors influencing vaccine hesitancy, focusing on influenza vaccinations in rural and urban communities in Romania. Methods: The study was conducted between October 4 and October 30, 2024, across 16 family medicine practices, including seven in rural and nine in urban areas from Romania. A 13-item vaccine hesitancy questionnaire, assessing factors such as fear of adverse effects, distrust in vaccines, and perceived necessity included 272 responses. Latent Class Analysis (LCA) was used to identify distinct subgroups of hesitancy, while Chi-square and odds ratio analyses assessed geographic differences. We performed logistic regression for the most observed root attitudes on influenza vaccination refusal. Results: Rural residents were significantly more likely to refuse influenza vaccination compared to urban residents. The LCA revealed three distinct latent classes, characterized by varying levels of agreement with key hesitancy items. Class 1 demonstrated low hesitancy, Class 2 exhibited high hesitancy driven by beliefs in natural immunity and perceived lack of necessity, and Class 3 showed intermediate hesitancy, influenced by distrust in vaccines and past negative experiences. Among the key significant triggers underlying vaccine refusal were fear of adverse effects, parental status, chronic diseases, and previous vaccination experiences, while factors such as age and gender showed limited impact. Conclusions: Vaccine hesitancy persists as a complex, multidimensional issue, with rural populations disproportionately affected. Targeted, context-specific interventions addressing key drivers such as distorted risk perception, fear of adverse effects and distrust in vaccines are critical for improving vaccination rates These findings underscore the importance of tailored public health strategies to promote equitable vaccine uptake.
