He said this during a speech before the UN General Assembly. 

“Omicron has become another warning.

The next option may be worse," TASS quoted him as saying.

Guterres also spoke about the importance of global vaccination, noting that its pace lags behind its goals.

According to the UN Secretary General, vaccination rates in high-income countries are seven times higher than in African countries.

“At this rate, 70% of those vaccinated in Africa will only be reached by August 2024,” Guterres said.

Earlier, Academician Vitaly Zverev said that the omicron strain will not be the last phase of the development of the coronavirus.

The FAN also reported that the molecular biologist, virologist Pyotr Chumakov, on the air of the Patriot media group, commented on the situation with the spread of the Omicron strain.
