Recently, Zhong Nanshan, an academician of the Chinese Academy of Engineering, said in an exclusive interview with China News Service that the new crown vaccine booster injection is closely related to the establishment of herd immunity.
Will it last a year after two injections?
It seems that our indicators are not enough.
Antibody titer is only one part of it, and the other part is cellular immunity.
After the booster is established, the more it is done, the more opportunities to establish herd immunity may be.
