Pfizer vaccine: It is 100% effective in teenagers aged 12 to 15 years

The Pfizer / BioMTech alliance on Friday requested that the emergency powers of its Kovid-19 vaccine be extended to the 12- to 15-year-old adolescents in the United States, which could launch a new key phase of vaccinations for mass immunity.

Immunity during adolescence can reduce the burden on many parents whose children are still in distance education.

The Pfizer / Bioentech alliance plans to make this request “to other regulatory authorities in the world in the coming days,” the two companies said in a statement.

The extension request, filed with the U.S. Medicines Agency (FDA), is based on data from phase 3 clinical trials at this age that have been shown to be “100% effective” in preventing the disease.

In late March, the companies published the results of their tests performed on 2,260 teens in the United States, exhibiting “strong antibody responses” after injections.

Pfizer and BioMtech added on Friday that the vaccine is “well tolerated” in people between the ages of 16 and 25 and the side effects are similar to what is commonly seen.

The vaccine is currently approved for people 16 and older.

Children are less susceptible to severe cases of the disease, so their vaccinations have not yet been prioritized.

But they represent a large part of the population, so it is important to have immunity to prevent the spread of the disease, experts argue.

We still do not know what percentage of the vaccinated population is needed to achieve this mass immunity: perhaps between 70% … or 85%, according to the most respected immunologist Anthony Fauzi.

In February, he estimated that American children under the age of 1222 could be vaccinated in early 2022.

The Pfizer / BioMTech vaccine, based on the latest messenger RNA technology, was the first vaccine against Kovid-19 to be approved in the West by the end of 2020.

In mid-March, the American company Moderna announced that it had begun testing its Kovid-19 vaccine on thousands of children aged 6 months to 11 years. Johnson & Johnson, the third vaccine authorized in the United States, also began testing in adolescents aged 12 to 17 years.

The United States, which has given a big boost to the vaccine campaign, has been taking an average of more than three million injections a day over the past 7 days, officials said.

More than 112 million people in the United States have received at least one dose of the Kovid-19 vaccine, according to data from the country’s leading federal health agency, the Public Centers for Disease Prevention and Control (CDC).

The United States is the most miserable country in the world in absolute terms, with over 560,000 deaths from over 31 million positive cases.
