In the COVID-19 pandemic many countries required COVID certificates, proving vaccination, recovery, or a recent negative test, to access public and private venues. We estimate their effect on vaccine uptake for France, Germany, Italy using counterfactuals constructed via innovation diffusion theory. The announcement of certificates during summer 2021 were associated - although causality cannot be directly inferred with increased in France 13.0 (95% CI 9.7-14.9) percentage points (p.p.) total population until end year, Germany 6.2 (2.6-6.9) p.p., 9.7 (5.4-12.3) p.p.
