COVID-19 | Booster dose works against Omicron variant, says leading US epidemiologist

stimulant doses of RNA Vaccines The anti-COVID-19 messenger works against omicron, so it is not necessary to use a new specific one against this variant, the chief epidemiologist at the White House said Wednesday. Anthony Fauci.

Fauci said at the press conference of a government task force EE.UU. In the face of the epidemic.

In this sense, the expert sent a “clear message” and encouraged Americans who had not been vaccinated to do so and who had already been vaccinated to go receive the booster.

However, when booster dose of vaccine Increases its effectiveness to 75% against omicron infections that lead to symptoms of COVID-19 disease.

Reinforcement required

“What this tells us clearly and emphatically is that the omicron variant certainly compromises the antibody effects of the two-dose mRNA vaccine and reduces overall protection,” he stressed.

However, he added, “Significant protection against severe disease is maintained in initial clinical studies and in vitro,” noting that the booster improves protection against omicron.

Two messenger RNA vaccines that require two doses are currently approved in the United States, namely Pfizer those of Moderna, and one that developed from an adenovirus, the Johnson & Johnson virus; He gave the green light to promote the three injections.

How can you assess whether it could lead to a more serious infection? Dr. Elmer Huerta explains.
