Summary
A multi-centered clinical follow-up study to investigate the long-term dynamic of COVID-19 antibody level after vaccination.
Detailed description
From December 2019, coronavirus disease 2019 (COVID-19), caused by a β-coronavirus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread across the globe. As of July 6, 2021, more than 180 million confirmed cases and around 4 million deaths have been reported globally. Till now, many treatment methods has gradually formed a consensus. At the same time, several domestic vaccines have been offered to the public for free inoculation in our country. However, due to the urgent form of the epidemic, the short vaccine development cycle and heavy tasks, there is no clear conclusion on the long-term changes in antibody levels after vaccination.Therefore, we plan to carry out a multi-center prospective observational trial to better understand the dynamic changes of the antibody levels in patients after vaccination.
