AIMS: The aim of the study was to investigate the relation between declared intention to get/not get vaccinated against COVID-19, prior to the start of the global vaccination program, and actual vaccine uptake. Moreover, reasons for getting vaccinated or rejecting it were measured along with declared intent and behavior. METHODS: Within a longitudinal design, a representative sample of 918 Polish people was surveyed in February 2021 and August 2021. In February 2021, participants were asked about their intention to get vaccinated against COVID-19 and the reasons behind it. In August 2021, the same group was asked about having been vaccinated, along with the reasons. RESULTS: A significant pro-vaccine shift from declared intent to behavior was observed, with many participants turning away from being anti-vaccine or undecided and getting vaccinated. Significant correlations with attitudes toward general mandatory vaccination of children were found. Increased support for anti-vaccine arguments was seen over time in the unvaccinated sample, and decreased support for pro-vaccine arguments was seen in the vaccinated sample. Several key arguments for and against vaccination were identified. CONCLUSIONS: Declared attitude toward COVID-19 vaccination is not fully consistent with vaccination behavior. Pro-vaccine changes in attitudes of previously anti-vaccine and undecided individuals indicate that these groups may be influenced to potentially accept the COVID-19 vaccination over time.
