How long is the protection period of the new coronavirus vaccine?

Xinhua News Agency, Beijing, April 9th ​​(Xu Penghang, Chen Xiyuan) How long is the protection period of the new coronavirus vaccine? Is the protection period only half a year? What should I do if the new coronavirus has mutated? Experts from China's disease control experts responded: After six months of protection, there will still be a certain degree of effectiveness, and the vaccine will still have a certain degree of protection against existing mutant strains.

Shao Yiming, a researcher at the Chinese Center for Disease Control and Prevention, said that the so-called half-year protection period only means that some people have low neutralizing antibodies after half a year.

Feng Zijian, deputy director and researcher of the Chinese Center for Disease Control and Prevention, said that at present, we have insufficient data on the protection period and durability of the vaccine.

In response to the mutant virus, Shao Yiming responded that the existing mutant strains can only partially reduce the protection efficiency of the vaccine.

Shao Yiming introduced that after being vaccinated with the new coronavirus vaccine, the vaccinators will build a basic immunity to the new coronavirus.

According to Yin Weidong, chairman of Beijing Kexing Zhongwei Biotechnology Co.

"In the past year, my country's new coronavirus vaccine research and development approval process has basically been straightened out.

Industry experts such as Shao Yiming urged that the current strain variation in the main epidemic areas of the global new crown pneumonia epidemic is still within controllable range, and large-scale vaccination should be carried out as soon as possible to build a stronger herd immune barrier, while also reducing the speed of virus mutation.
