Course: SARS-CoV-2 Antibody Response After ChAdOx1 nCoV-19 Vaccination in Persons With Previous SARS-CoV-1 Infection

CME Credits: 1.00

Released: 2022-01-24

A nosocomial outbreak of severe acute respiratory syndrome (SARS) (caused by SARS-CoV-1) occurred at the Kaohsiung Chang Gung Memorial Hospital (KCGMH) in 2003. Sixteen health care workers (HCWs) had SARS-CoV-1 infection. In 2021, a community outbreak of SARS-CoV-2 occurred in Taiwan. It is potentially possible that individuals with prior SARS-CoV-1 infection were protected from infection. If so, antibody levels after vaccination might be higher than in individuals who did not have SARS-CoV-1 infection. This study assessed antibody levels after ChAdOx1 nCoV-19 vaccination (AstraZeneca) in individuals with previous SARS-CoV-1 infection compared with uninfected individuals who received ChAdOx1 vaccination.
