Covid-19 Vaccine Clinical Trial
Official title:
Serological Response to mRNA and Inactivated COVID-19 Vaccine in Health Care Workers in Hong Kong
Since the first local case of COVID-19 confirmed on 4 Feb 2020, Hong Kong has already experienced 4 waves of COVID-19 surge, with more than 9000 cases reported. A number of vaccines have been shown to be efficacious against symptomatic and severe infection by inducing neutralizing antibody (NAB) against spike protein of the SARS-CoV-2 virus. However, the duration of protection and longevity of antibody response is unknown. Health care workers (HCWs) who are planning to receive COVID-19 vaccine will be recruited. The level of antibody against spike protein by different quantitative assays will also be serially measured .
