Hong Kong scientists warn omicron could drastically reduce vaccine effectiveness

The new omicron coronavirus strain could reduce the ability of the Pfizer / BioNTech vaccine to neutralize the virus by 32 or more times. This is evidenced by the research data of Hong Kong scientists.

As stated at the University of Hong Kong, “a recent study” showed that “omicron” can “significantly reduce the ability of the Pfizer / BioNTech (BNT162b2) vaccine to neutralize the virus by 32 or more times,” RIA Novosti reports.

Now experts are testing another vaccine used in Hong Kong – CoronaVac from the Chinese pharmaceutical giant Sinovac.

Earlier, scientists from South Africa said that the effectiveness of two doses of the Pfizer coronavirus vaccine against the omicron strain is only 22.5%, according to PRIME.

Add, a new strain of coronavirus B.1.1.529, which contains 32 mutations in the S-protein, was first identified in South Africa and Botswana in early November. The infected were found in Hong Kong, Belgium, Israel. At an emergency meeting on November 26, the World Health Organization recognized B.1.1.529 as “of concern” and named it “omicron” after the 15th letter of the Greek alphabet. Omicron has a large number of mutations, it also spreads faster than the delta type. A new strain of coronavirus with increased mobility has been found in more than 55 countries, including Russia.
