 This study examined Polish COVID-19 vaccination data from January 2020 to January 2023 to better understand how people make decisions about getting vaccinated. It found that overall vaccination rates declined as the number of government provided doses increased, particularly among elderly individuals and those aged 70 to 79. Additionally, healthcare workers showed a dramatic shift in their attitudes towards vaccination, with many choosing not to get the second dose. However, two factors positively affected vaccination decisions, societal influence, and the availability of updated boosters. Low-risk individuals were more likely to postpone vaccination until updated boosters became available. This study suggests that Polish policy should be revised to focus on vaccinating vulnerable populations and those with close contact with them before the flu season begins.
