Spillover Effects of the COVID-19 Pandemic on Attitudes to Influenza and Childhood Vaccines

The aim of the current study was to explore whether the COVID-19 pandemic has affected people’s perceptions of other vaccines and diseases than COVID-19. In two samples of Finnish adults (N = 205 in Study 1 and N = 197 in Study 2), we longitudinally investigated whether there has been a change from before the COVID-19 pandemic to during the pandemic in: 1) influenza vaccination behavior and intentions, 2) the perceived benefit of childhood vaccines and influenza vaccines, 3) the perceived safety of childhood vaccines and influenza vaccines, 4) the perceived severity of measles and influenza, and 5) trust in health care professionals and health authorities in vaccine-related matters. The results indicated that more people had taken or had wanted to take the influenza vaccine during the pandemic than before. The respondents also considered influenza as more severe, and influenza vaccines as more beneficial and safe during the pandemic. For childhood vaccines, by contrast, there was only an increase in the perceived safety of the vaccines. Finally, in one of the studies, trust in health care professionals was higher during the pandemic than before. Taken together, these results suggest a spillover of the COVID-19 pandemic on people’s perceptions of other vaccines and diseases.
