Lung Function, Exercise Capacity, and Serology Responses in Patients With COVID-19

August 19, 2024 updated by: Prof David Shu Cheong Hui, Chinese University of Hong Kong

(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)

Study Overview

Detailed Description

The health conditions of adults (N=300) who recovered from varying severity of COVID-19 will be assessed and their blood are collected at 6, 12, 24 and 36 months after discharge. The assessment package includes: lung function tests, 6-min walk distance, chest radiographs/CT, and SF36 General Health questionnaire. Blood samples from community cohorts will be collected from before and up to 36 months after receiving one of the three COVID-19 vaccines (N=200 per vaccine type). The kinetics of SARS-CoV-2 specific humoral and cellular immunities from both convalescent and vaccinated cohorts are determined by neutralization assay and by measuring specific T cell responses upon stimulation of SARS-CoV-2 specific peptide library respectively. The antiviral level of the human plasma with various neutralization titer collected from different vaccinated cohorts will be tested in mouse model and ADCC assay.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
COVID survivors
Vaccination with CoronaVac vaccine
Healthy individuals to receive Coronavac vaccine 2 doses, 21 days apart
Vaccination with BionTech vaccine
Healthy individuals to receive BionTech vaccine 2 doses, 21 days apart
third dose vaccination with CoronaVac vaccine
We propose to invite 80 participants who have already completed the 2 doses vaccination of CoronaVac with low level of neutralizing antibody at 1-month post-vaccination to join this additional study. They will be randomized to receive a booster dose of Coronavac or BionTech in equal numbers (n=40 each group).
Healthy individuals with low antibody levels after 2 doses of CoronaVac vaccine to receive one additional dose of CoronaVac vaccine
third dose vaccination with BionTech vaccine
We propose to invite 80 participants who have already completed the 2 doses vaccination of CoronaVac with low level of neutralizing antibody at 1-month post-vaccination to join this additional study. They will be randomized to receive a booster dose of Coronavac or BionTech in equal numbers (n=40 each group).
Healthy individuals with low antibody levels after 2 doses of CoronaVac vaccine to receive one additional dose of BionTech vaccine
