Fauci identifies the best way to prevent corona

Anthony Fauci, the chief infectious disease expert in the United States, said that taking three doses of vaccines is the "optimal care" of the emerging coronavirus (Covid-19).

Fauci, who is director of the National Institute of Allergy and Infectious Diseases, told ABC News that health officials will continue to assess what should be a formal definition.

Asked if three doses of vaccines might be the new standard of care, Fauci said: "Well, I definitely think it represents the best care."

"I mean, in terms of formal requirements, the two doses of Pfizer/Biontech or Moderna or the dose of Johnson & Johnson still fit the official definition of what is required. But I think if you look at the data, it becomes more and more clear that if you want to be protected in the way that Optimally, you really have to get a booster dose."

Fauci added that it will take months to determine whether there is a need to receive annual booster doses of vaccines, explaining that he hopes from an immunological point of view that a single booster dose will be sufficient to provide greater protection than the six months provided by the initial vaccine.
