= .0002). Female and HCWs aged 18-30 y were more likely to report AEs. The most common AEs were local reaction, accounting for 48.1% and 67.4% of all AEs after the first and second dose respectively. The systemic AEs were mainly neurological (9.8% and 4.8% after the first and second injection respectively) and flu-like symptoms (6.3% and 3.2%). Overall, most of AEs were mild, only 5.1% (after the first dose) and 2.8% (after the second dose) of individuals with AEs received symptomatic treatment or sick leaves, and none of them required hospitalization. Our data added more evidence that inactivated COVID-19 vaccines are highly safe. The data are valuable to overcome vaccine hesitancy associated with concerns about the safety of COVID-19 vaccines.
