The European regulator warned against revaccinations more than once every four months

The European Medicines Agency (EMA) has warned against revaccinating against coronavirus more than three times a year or every four months - otherwise there is a risk of weakening the immune system of people. The world must begin the transition from a pandemic response to the coronavirus to an endemic one, similar to the long-established one for the influenza virus - with approved seasonal vaccination schedules.

"While the use of booster vaccines may remain part of contingency plans, a revaccination strategy at short intervals is not viable," told Reuters. Marco Cavaleri, head of EMA vaccination strategies,

The Agency still sees no evidence of benefit from the fourth dose of the vaccine (second booster) that Israel has already begun to use for vulnerable populations.

The EMA acknowledges that the collected data on the interaction of the omicron strain with vaccines and its epidemiological features are not yet sufficient to make a decision on the need for a specific omicron-specific vaccine. But if such a decision is made, new vaccines cannot be approved before April. With their massive use, worldwide coordination is needed, Cavaleri emphasized.

• By all indications, the omicron-wave of coronavirus will be higher than all the previous ones due to its high contagiousness (with not such a high mortality rate). This week, an absolute record of daily incidence was set in the United States, and WHO warned that half of the population of Europe could become infected with “omicron” in the next one and a half to two months (more on this here ) .
• The Russian authorities also spoke about the danger of a new wave. On the eve of Moscow Mayor Sergei Sobyanin admitted that the situation in the capital may be "more critical" in comparison with previous waves of morbidity. Today, President Putin said that Russia has two weeks to prepare for a new round of covid.
