Study on Three Doses of an Inactivated COVID-19 Vaccine in Chinese Pulmonary Tuberculosis Patients
Study Details
Study Description
Brief Summary
This is a randomized, double-blind, parallel-controlled study, for evaluation of safety and immunogenicity of three doses of an inactivated COVID-19 vaccine (CoronaVac) in pulmonary tuberculosis patients aged 18-75 years. 200 tuberculosis patients and 40 healthy adults aged 18-75 years will be recruited in this study. Of them, 200 pulmonary tuberculosis patients will be randomized at a 1:1 ratio to receive two doses of standard dosage CoronaVac plus one dose of double dosage CoronaVac or two doses of standard dosage CoronaVac plus one dose of standard dosage CoronaVac at a schedule of 0, 28, 56 days, respectively. Other 40 healthy subjects served as an external control group will be vaccinated with two doses of standard dosage CoronaVac at a schedule of 0, 28 days. The occurrence of adverse events within 28 days after each dose vaccination and serious adverse events within 3 months after full vaccination will be observed. In addition, blood samples will be collected on day 0 before the first dose and 28 days and 3 months after the last dose vaccination in all participants and 28 days after second dose in pulmonary tuberculosis patients. Each subject will remain in this study for 5 months (healthy group) or 6 months (tuberculosis group).
