We here investigate the role of risk aversion in COVID‐19 vaccine hesitancy. The theoretical effect is ambiguous, as both COVID‐19 infection and vaccination side‐effects involve probabilistic elements. In large‐scale data covering five European countries, we find that vaccine hesitancy falls with risk aversion, so that COVID‐19 infection is perceived as involving greater risk than is vaccination.
