Abstract
Background and Objectives: This study delves into the attitudes, beliefs and determinants influencing the uptake of the COVID-19 vaccine among the Lithuanian population. Materials and Methods: Utilizing a cross-sectional study design, a total of 3166 respondents were surveyed. Results: The findings reveal a significant disparity in vaccination rates based on socio-demographic factors, with higher uptake observed among individuals with a university degree, urban residents and those in higher income brackets. Personal beliefs, particularly regarding the vaccine's efficacy in pandemic management, played a pivotal role in vaccination decisions. This study also highlights the influence of external factors, such as the activity of the "anti-vaxxer" movement and the introduction of vaccination certificates. Conclusions: The results emphasize the need for targeted educational interventions and comprehensive public health campaigns to address vaccine hesitancy and promote widespread immunization.
