At present, China is stepping up efforts to vaccinate the population to achieve herd immunity as soon as possible, but at the same time it remains vigilant and actively conducts research to find more effective vaccines and antibodies against COVID-19.

This was stated by the leading Chinese epidemiologist Zhong Nanshan, speaking at the Great Bay Region Scientific Forum 2021 in Guangzhou (Guangdong Province, South China).

The authoritative expert noted that in theory, vaccination in China will provide herd immunity when its level reaches 83% of the country's population. China is expected to achieve this by the end of this year.

As of Thursday, more than 1.15 billion people in China have completed the full course of COVID-19 vaccination, which is 81.9 % of the country's population.

"Theoretically, if the COVID-19 vaccine provides approximately 70% protection against the virus, then [China will develop herd immunity] when the vaccination rate of the population reaches at least 83%", Zhong Nanshan said.

As for the Omicron strain, as of Friday, 27 US states have confirmed cases of infection with this variant of the coronavirus.
< br> And in South Africa, where the omicron variant was first identified, almost 90,000 new confirmed cases of COVID-19 infection were reported from November 7 to December 4. Meanwhile, in the province of Gauteng, hard hit by the epidemic, the number of new cases increased by more than 400% in the week from November 28 to December 4 compared to the previous week.

This also confirms the assumption Zhong Nanshan that the strain of coronavirus "omicron" is more contagious. The expert noted that the "delta" variant had 3 mutation areas, while the "omicron" variant had 15.

"In addition, people now know little about the virulence of the omicron variant. Some say, that it has a higher virulence. However, many countries, including South Africa and the United States, have noted that its virulence is not particularly strong. So we cannot draw conclusions today. The overall situation with this variant is still under observation, "said < b>Zhong Nanshan.

"Now we also don't know if the protective power of vaccines will be weakened or the neutralizing ability of antibodies will decrease. If we find that this is the case, we will immediately prepare. So now we so many of our vaccine companies, universities and research groups have this virus alive, we are all active and around the clock We are actively conducting research to find even better vaccines and antibodies," the Chinese expert concluded.
