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 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.
