Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Evaluation of immunogenicity, safety and persistence of the subjects aged 60 years and above with chronic bronchitis and chronic obstructive pulmonary disease received the third dose of inactivated COVID-19 vaccine .

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The subjects aged 60 years and above with chronic bronchitis and chronic obstructive pulmonary disease recruited to receive a third dose of inactivated COVID-19 vaccine.

Blood samples will be collected 3 times: before the third dose of vaccinatioin,28 days and 6 months after the third dose of vaccination.

Any local or systemic adverse events that occurred within 21 days after vaccination will be recorded.
