Oct 29, 2022 · Results. We identified 1656 individuals who had their first seizure‐related hospitalization (BNT162b2: 426; CoronaVac: 263; unvaccinated: 967) within the observation period. The incidence of seizure was 1.04 (95% CI .80–1.33) and 1.11 (95% CI .80–1.50) per 100 000 doses of BNT162b2 and CoronaVac administered, respectively.
Aug 11, 2022 · For CoronaVac, the vaccine effectiveness was 44% (95% CI: 37%–49%) and 70% (95% CI: 64%–75%) for COVID-19–related hospitalization and death, respectively. Table 1 summarizes the results of the vaccine effectiveness for both vaccines.
