Therefore, allows for the identification of similarities and divergences in the disposition towards vaccination, which is key for the design of more effective and culturally sensitive educational and public health strategies.MethodsThis cross-sectional study assessed and compared attitudes and behaviors toward vaccination among nursing students from the Portuguese Catholic University (Lisbon, Portugal) and the Complutense University of Madrid (Spain). The study included 928 students from all four years of the nursing degree program, who completed the Questionnaire on Attitudes and Behaviors toward Vaccination in Health Sciences Students (ACVECS).ResultsThe results showed significant differences between both countries. Spanish students presented more favorable attitudes and behaviors toward vaccination compared to Portuguese students (p < 0.001). Women and native students obtained higher scores. Differences were observed according to academic year: in Spain, students in higher years showed better attitudes, while in Portugal it was first-year students who obtained higher scores. These differences could be influenced by cultural, educational, and pandemic-related factors.ConclusionsSpanish students showed significantly more favorable attitudes and behaviors toward vaccination than Portuguese students. Native students had a better attitude toward vaccination in both countries, this difference being especially notable in behaviors oriented toward vaccination among Portuguese students.
