COVID-19 vaccination certificates and lifting public health and social measures: ethical considerations.

Vaccination certificates may undermine a population-based approach to COVID-19 vaccination to achieve and accelerate universal lifting of PHSMs, result in unfair and inequitable health and social outcomes, and generate social divisions at a time when solidarity within (and between) countries is necessary to navigate the pandemic and its burdens. Further research on the ethical acceptability and impact of COVID-19 vaccine certificates in countries that have implemented them should be carried out to inform future ethical considerations on this issue.
