Popular press and academic articles alike speculate that gender influences vaccine receipt, but they often disagree whether men or women are less likely to become vaccinated. In the current article, we further test the relation of gender and vaccination in four datasets, and we assess the mediating role of vaccine hesitancy dimensions. Our results demonstrate that: (1) gender has significant relations with several vaccine hesitancy dimensions, which are mixed between both women and men having negative perceptions regarding vaccination; (2) gender does not significantly relate to flu and COVID-19 vaccination willingness or receipt, but women were more likely to receive other vaccines; and (3) a significant indirect effect did emerge in the two datasets collected after widespread access to the COVID-19 vaccine, such that the perception that vaccines cause health risks mediates the relation of gender with flu vaccination willingness as well as COVID-19 vaccination willingness and receipt. Our discussion integrates these findings with models of preventative behaviors and identifies directions for future research.
