Academician Zhong Nanshan stated on January 31 that China's vaccines are safer and the production of antibodies will last for at least half a year.
Zhong Nanshan said that the Chinese vaccine has been used for 7 months, almost 8 months, and the antibody is still at 90%.
The most important thing about vaccines is safety, and the safety and reliability of fully inactivated vaccines are relatively high.
The general side effect of mild cases is 6 per 100,000, that is, some fever after the fight, some pain in the arm, and 1 per million in severe cases.
We usually get three parts per million of the flu vaccine.
There will be adverse reactions to all vaccines, and it is impossible to have no response 100%.
The two Chinese vaccines, Sinopharm and Kexing, have vaccinated more than 20 million people worldwide.
