Is COVID-19 No. 3 harmful to human health? How long is the validity period of COVID-19 vaccine?

Harm of COVID-19 Vaccine to Human Body

Generally, COVID-19 Vaccine will not cause harm to human body. In the Technical Guidelines for COVID-19 Vaccination (the first version), the population vaccinated with COVID-19 vaccine is 18 years old and above. After vaccination, only a small number of recipients may experience local pain or redness in their bodies, which can be relieved in about two days and will not affect their own health.

How long is the validity period of COVID-19 vaccine

at least 6 months. Because COVID-19 is a very new virus, the existing data shows that after COVID-19 infection, it is rarely infected with COVID-19 within six months. However, this does not mean that protection will not be available after 6 months. It is just a short time since the development of COVID-19 vaccine, and no longer observation data is available. In the future, research on the durability of the vaccine is needed to confirm how long its protection period is. However, at present, 6 months after the injection of COVID-19 vaccine, there is still a high antibody level.
