Brief Summary

After SARS-COV-2 inactivated vaccine authorization for use in different countries including Egypt, investigating its immunogenicity, safety, and efficacy in preventing COVID-19 infection is highly needed. In Egypt, immunization of HCWs in isolation hospitals by SARS-COV-2 inactivated vaccine is now a national priority. Moreover, data and reports regarding the application of vaccine are still limited and deficient.
