According to her, to suppress the new wave, it is necessary to vaccinate 25% of the population in Russia in two months, or about 30% by May.

"We must vaccinate either 25% of the country's population, if we talk about a fairly one-time high campaign that will last no more than two months, or if this campaign is stretched until May and inoculated consistently, then it will take about 30%," RIA quotes her News.

As Skvortsova noted, her calculations are based on information that the vaccine has an efficiency of about 94% and post-vaccination immunity lasts more than six months.

Earlier, the Director of the Regional Office for Europe of the World Health Organization (WHO) Hans Kluge expressed concern about the worsening situation with the coronavirus in Europe.
