On Tuesday, American health regulators approved a second Coronavirus booster dose for 50-year-olds and up, a move to provide additional protection for the most susceptible in case the lethal SARS-CoV-2 rebounds. The decision by U.S. FDA opens another dose – fourth overall – of the messenger-RNA vaccines by Moderna or Pfizer-BioNTech to that age cohort at least 4-months after the initial booster injection.
So far, the U.S. federal health agency has cleared 4th shots only for 12-year-olds and up who have severely weakened immune responses. Moreover, the regulator said this particularly fragile age group could receive one more booster shot, overall 5th COVID-19 dose.
TODAY: FDA authorizes second booster (4th dose) 4 months after 3rd Pfizer/ Moderna dose for 50+, or 12+ & immunosuppressed.
CDC is expected to weigh in later with their recommendations.
All being done without convening the external expert review panels for commentary/vote.

Dr. Peter Marks, FDA vaccine chief, said that based on an investigation of emerging data, the 2nd booster of either the Moderna or Pfizer-made jab could help boost immunity for the above-specified people. And the U.S. CDC later endorsed in line with the Food and Drug Administration, saying that more booster shots were safe and effective, permitting people to boost their defense further.
According to data from the US CDC (Centers for Disease Control and Prevention), coronavirus infections in America have decreased sharply since a record rise in Jan. 2022, but have observed a slight increase during the last week.
Peter Marks said that every American eligible for a 1st booster dose who has not received one yet needs to. However, the fourth vaccine shot is only for these higher-risk individuals because there’s proof immunity can decline, and Food and Drug Administration selected the option will help save the lives of people and avoid tough moments.
Furthermore, the action comes at a time of great uncertainty. Coronavirus infections have decreased to lower levels after the Winter rise of the highly contagious Omicron variant of the SARS-CoV-2. Moreover, the US CDC data displays that the two vaccine injections with the third one as a booster still offers robust protection against serious disease and unfortunate fatality.
However, a sibling of super-contagious Omicron is causing a ‘worrying jump’ in cases in the West and transmitting in America even as immunizations have caught up. Approximately 66 percent of the US population has received their primary doses, and 50% of those booster-eligible haven’t received their initial booster.
Manhattan, New York-based pharmaceutical firm had requested the US federal health agency to approve the 4th dose of its vaccine for 65-year-olds and up, while Cambridge, Massachusetts-based Moderna Inc, asked for one more shot for all American adults to offer flexibility for the US administration to determine the eligibility.
Recently, the CDC reported that two vaccine shots were about eighty percent productive against needing a ventilator or fatality – and a booster dose pushed that protection to 94 percent during the Omicron-wave in the U.S. Moreover, the effectiveness of the COVID-19 jab was a minimum of 74 percent in immunosuppressed individuals, the extensive majority of whom had not received the first booster.
President Biden To Receive Additional COVID-19 Booster
Katherine Joan Bedingfield, the White House Communications Director, said during the news conference that Joe Biden, the President of America, will get an additional coronavirus vaccine booster dose if his doctor recommends after the US FDA expanded EUA of 2nd Moderna or Pfizer-BioNTech booster injections for 50-year-olds and up around 4-months after getting third shot.
