Overall and sex-specific age-standardised incidence of Bell's palsy in people after CoronaVac and BNT162b2 vaccination and in the background population in Hong Kong

The background incidence was calculated using the same reporting period in 2010–20 as for each vaccination programme in 2021 (for CoronaVac, Feb 23–May 4; for BNT162b2, March 6–May 4). In the female group, the number of reported and clinically confirmed cases in people exposed to BNT162b2 were the same. Thus, the lines for reported and clinically confirmed cases in BNT162b2 overlap. The error bars are 95% CI of the age-standardised incidence.
