Effectiveness of vaccination mandates in improving uptake of COVID-19 vaccines in the USA
In this Viewpoint we consider the likely effectiveness of policies that require COVID-19 vaccines in improving vaccine uptake and reducing disease in the USA, in view of the evidence from past vaccination mandates and distinctive aspects of COVID-19. Two dimensions of effectiveness in improving uptake are relevant: (1) target-group effectiveness (the extent to which a mandate improves uptake of vaccines in the group covered by the policy) and (2) population effectiveness (the extent to which mandate policies improve vaccination coverage in the US population).
