Is the second dose of COVID-19 vaccine inactivated or attenuated? How many times should COVID-19 be vaccinated?

1, COVID-19 vaccine has been inactivated.

2. The research and development time of COVID-19 vaccine is relatively short, and its stability is not particularly certain. At present, it has been widely vaccinated (202 1 1), but only for some high-risk groups, such as cold chain workers, medical personnel, ship personnel, hotels, airports and other high-risk groups.

3. COVID-19 vaccine needs to be injected twice with an interval of 14~28 days. Generally, antibodies will be produced within two weeks after the second vaccination. After vaccination with COVID-19 vaccine, you should observe the vaccination site for 30 minutes, and leave only if there are no symptoms.
