Pfizer presented preliminary results supporting using the third dose of its coronavirus vaccine in the United States.


The laboratory provided the FDA with data pointing to a significant increase in antibodies with a booster applied between eight and nine months after the second injection.

Pfizer and BioNTech announced Monday that they had released preliminary results of their clinical trials to US authorities as part of their effort to get a booster dose of the The COVID-19 vaccine is approved for everyone over the age of 16.

So far, the Food and Drug Administration (FDA) has approved a third dose of Pfizer and Modern for people with weakened immune systems because they did not respond as normal to the vaccine as the general population, which estimates that it Represents 3% of the country's population.

According to data provided by Pfizer on Monday, the booster dose generated "significantly higher neutralizing antibodies" against the original strain of the coronavirus, in addition to the beta and delta variants, the company said in a statement.

Participants in the clinical trial received a third dose between eight and nine months after the second, the text specified.

"The data we have seen so far shows that a third dose of our vaccine achieves antibody levels that are significantly higher than the first two doses," Pfizer CEO Albert Borla said in a statement.

"We are pleased to present this data to the FDA as we continue to work together to address the changing challenges of this epidemic," he added.

Pfizer further revealed that it expects to receive results from the final stages of booster dose clinical trials soon, which it will present to FDA and regulatory authorities around the world.

The data is known three days after the US authorized administering the third dose for people with a weakened immune system, such as organ transplant patients, people with HIV, or some cancer patients, who did not register an adequate immune response to the first two vaccines.

At the moment, health officials are not recommending a booster diet for the general population. Still, the main epidemiologist of the US government, Anthony Fauci, recently stated that it "probably" will be necessary at some point.

According to local media, The New York Times, and The Washington Post, the United States plans to announce that almost all its citizens should receive a booster dose eight months after being immunized, a new phase in the vaccination campaign that could begin in mid-September. The two newspapers, which cited officials familiar with the government's decision, suggest that the official announcement could be made this week.

The World Health Organization (WHO) has called for a global moratorium on a third dose of the vaccine until the end of September because it considers that if countries begin to administer it, it will not help the global distribution of serums against the covid, while the Union Europea has ensured that there is still not enough evidence that they are necessary.
