The Centers for Disease Control and Prevention (CDC), the federal federal public health service, recommended Thursday that a third dose of the Pfizer / BioNTech vaccine be given to Americans 65 years of age and older, under the age of 19. at risk of developing severe COVID-XNUMX.
However, the committee did not recommend the provision of supportive doses to younger adults, including health professionals, whose work poses a high risk of being infected with SARS-CoV-2, which may limit the scope of the emergency authorization application. approved by the FDA, the federal drug agency, one day earlier (24718217).
The guidelines voted on by the CDC's immunization advisory committee remain to be approved by the institution's director, Rochelle Wallenski. Its recommendations are also not binding; states and other jurisdictions could defy them and adopt their own approaches to booster doses.
However, the vote and the approval of the FDA pave the way for the start of the third dose this week for millions of Americans who received the second dose of their vaccine at least six months ago.
In addition to those over 65, the committee also recommended third doses for adults over 50 with underlying diseases and 18-49 years with the same diseases (cancer, diabetes, heart disease, kidney disease and lung disease) because they were at high risk.
The population of this recommendation numbers about 26 million people, including 13 million Americans 65 and older.
The committee did not approve the aid installments for healthcare, education, homelessness and prison inmates, in part because of the difficulty of implementing this recommendation. He may return to the issue in the future.
The government of President Joe Biden announced in August that it intends to begin providing supportive doses to Americans 16 years of age and older this week, following approval by the FDA and CDC. He explained that new data show that the immunity offered by vaccines decreases over time.
More than 180 million people in the United States - 64% of the eligible population - are fully immunized.
Pfizer, like some U.S. health officials, such as immunologist Dr. Anthony Fauci, argue that the third, boosting doses will eliminate the problem of reduced immunity. Dr. Fauci and others also believe that they can reduce the increasing hospital admissions and deaths caused by the most contagious Delta variant of the virus, in particular reducing fully vaccinated infections.
The wave of hospital admissions, mostly unvaccinated, may have already peaked, although the United States continued to record some 1.500 deaths from COVID-19 a day last week, according to CDC data.
Some countries, such as Israel and Britain, have already begun to provide aid. The United States approved booster doses for immunocompromised patients last month, and more than 2,3 million people have already taken them, according to the CDC.
The United States remains the world hardest hit by the new coronavirus pandemic in the world, with more than 681.000 dead from COVID-19 out of a total of 42,55 million SARS-CoV-2 infections.
