Anthony Fauci assured that the three doses of vaccine against coronavirus are the standard of "best care."

It is becoming increasingly clear that if you want to be optimally protected, you have to put on a reinforcement," said the epidemiological chief of the White House.

Three doses of the coronavirus vaccine are the "optimal care" standard, but two doses of the Pfizer / BioNTech or Moderna immunizations or one of the Johnson & Johnson vaccines remain the official government standard for being fully vaccinated. The leading expert on infectious diseases in the United States, Anthony Fauci, said this Sunday.

The health authorities will continue to evaluate which scheme should constitute the official designation, added the director of the National Institute of Allergies and Infectious Diseases and the main medical adviser to President Joe Biden, in the program "This Week With George Stephanopoulos" of the ABC network.

I definitely think this is the best care, Fauci said in response to the question of whether three doses of the vaccine could be the new standard of care.

I mean, for official requirements, these are still two injections of mRNA (Pfizer / BioNTech or Moderna) and one injection of J&J to determine if it is needed. But I think if you look at the data, it's becoming increasingly clear that you have to reinforce if you want to be as secure as possible.

It will take months to find out if annual booster doses of the vaccine are necessary, Fauci said, adding that, from an immunological point of view, he hopes that a booster dose is enough to provide protection greater than the six months that offers the initial vaccine.

The White House chief of epidemiology cited vaccination schedules amid concerns about the progress of the Omicron variety.

This Sunday, the World Health Organization (WHO) indicated that new tensions appear to be spreading beyond the Delta, with mild symptoms. In addition, according to preliminary data from the body, vaccines against this type will be less effective.

Omecron was present in 63 countries as of December 9. The World Health Organization recently reported in a technical update confirming the statements of its officials.

According to the WHO, Ómicron seems to spread faster than the delta variant, which until now is responsible for the majority of infections in the world.

This faster advance is not exclusive to South Africa, where delta is less prevalent, but also in the UK, where delta is dominant.

But for now, the lack of further information prevents us from confirming whether Omecron's delivery rate is due to the fact that it is able to suppress the immune system because its properties make it more contagious or both. Makes a combination of factors.

The WHO predicts that "Amicron leaves the Delta behind where there is a community transmission."

The data are still insufficient to establish the level of severity of the clinical picture caused by Omicron, even if at the moment the symptoms appear to be "mild to moderate" in both southern Africa and Europe.

With regard to vaccines, some available data show that the genetic profile of Ómicron reduces its effectiveness in protecting against infectious diseases.

Manufacturer Pfizer / BioNTech indicated last week that a three-dose vaccination schedule is effective against Omicron.

Countries that have the resources are encouraging the population to take a third dose.

The situation is similar in Europe, where a new wave of infections is spreading due to delta breakdown, abandonment of preventive measures and low vaccination rates in some countries.
