Sponsor: Chinese University of Hong Kong

View on ClinicalTrials.gov

Summary

(a) Objectives 1. To assess the full lung function, exercise capacity, quality of life in patients with COVID-19 over 2 years. 2. To assess the longevity of the serology response to SARS-CoV2. 3. To investigate the association of the neutralization titer in plasma from different vaccinated cohorts to its protection of infection using in vivo model 4. To investigate the SARS-CoV-2 specific cellular and humoral immunities as well as their determinant factors from community subjects who have received different types of COVID-19 vaccines. 5. To assess the third booster dose for subjects who have poor antibody response despite having received two doses of CoronaVac (Sinovac)
