Abstract

There is limited evidence on vaccine effectiveness against asymptomatic or mild Omicron infections. We estimated that recent third doses of messenger RNA or inactivated vaccines reduced the risk of self-reported infection by 52% (95% confidence interval, 17%–73%) among randomly sampled adults during the Omicron BA.2–dominated surge in Hong Kong.
