The US FDA has approved a third dose of the COVID-19 vaccine for people with weakened immune systems.


The emergency use approval for the drugs from the pharmaceutical companies Pfizer-BioNTech and Moderna applies to patients who received solid organ transplants and weak immune systems.

The U.S. Food and Drug Administration (FDA) authorized third doses of the Pfizer-BioNTech and Moderna coronavirus vaccines for people with weakened immune systems, giving doctors more freedom. Of action to protect those who did not respond sufficiently to an initial series of injections.

The FDA said the current emergency use of the two vaccines applies to those who have had solid organ transplants and others who have similarly compromised immune systems.

The agency's decision comes a day before the Independent Advisory Committee of the Centers for Disease Control and Prevention (CDC) was set up, which will consider whether or not to recommend the move.

The committee is likely to give its approval. The CDC will continue to support its endorsement of the additional doses.

The FDA is particularly aware that people with immune disorders are at particular risk for serious illness, "FDA Commissioner Dr. Janet Woodcock said in a statement. After a thorough review of the available data, the FDA determined that this small, vulnerable group could benefit. The third dose of Pfizer-BioNTech or Moderna vaccine.

he noted.

For the rest of the people outside the immunosuppressed group and who are vaccinated with the full schedule, the FDA stressed that they are still "adequately protected and do not need an additional dose of the covid-19 vaccine at this time."

This notice comes when local media have uncovered that some people in the United States are taking advantage of the lack of rigorous controls to receive the third dose without being approved or recommended by the authorities.

The United States thus joins other European countries and Israel, who have announced that they will begin to administer the third dose to the population at risk in the coming weeks.

This is even though the World Health Organization (WHO) last week asked rich countries for a global moratorium on a third dose so that there are enough vaccines to immunize at least 10% of the population of each country and thus protect those who are at higher risk of developing a serious illness and dying.

According to official CDC data, 59.2% of Americans have received at least one dose of any vaccines, and 50.2% have the full schedule.

These are low percentages for a country with enough vaccines for its entire population for months but have been met with skepticism and rejection by some sectors, especially racial minorities and conservatives.

To date, 619,093 people in the United States have died from COVID-19, and more than 36 million have been infected, according to an independent count from Johns Hopkins University.


The main epidemiologist of the United States Government, Anthony Fauci, recalled this Thursday the vaccination process is dynamic and that all data must be examined to adopt a resolution. However, he stressed that the Government is preparing for the eventuality of administering a booster dose.

"We do not believe that the elderly and the not elderly who are not immunocompromised need an (extra) vaccine right now," Fauci clarified.

Regarding the possibility that this booster dose is given to other groups of people in vulnerable situations, Fauci left the decision in the hands of the CDC and reported that "as soon as" more data becomes available, the list will be updated. Will be done

As soon as they confirm that the level of sustainability of protection has decreased, a recommendation to vaccinate them will be announced, "he said, referring to the elderly and those living in the dormitory.

"If the statistics show us that we have to do it, we will be very ready to do it quickly," he added.

Vaccines are still doing what they were originally wanted to do, keeping people out of the hospital and preventing them from getting seriously ill,"  emphasized Fauci, who has again warned of the daily increase in coronavirus cases, surpassing the 100,000 barrier, mainly due to the much more contagious Delta variant.

The epidemiologist explained that this type could transmit the disease to infected people, which is why the CDC recently revised its recommendations on the use of masks in closed areas.

He also indicated that the increase in cases in the country due to the spread of the Delta variant could be reversed with additional vaccines.

Last weekend, the COVID-19 epidemic in the United States crossed 100,000 newly confirmed cases a day, exceeding the threshold during an increase in pre-winter infections and a highly contagious delta virus. Due to the low rate of vaccination in the South.

At the end of June, the United States received an average of 11,000 cases a day. That number is now 107,143.

The virus is spreading rapidly through unsafe people, especially in the south of the country, where patients are crashing into hospitals.

The number of Americans hospitalized by the virus has also skyrocketed. The crisis has escalated to the point where many hospitals are finding it difficult to find beds for patients in remote locations.
