BREAKING NEWS: FDA will allow fully vaccinated Americans to get COVID-19 booster shots that are different than the vaccine they initially received

  • Officials are expected to approve extra doses for the Moderna and Johnson & Johnson shot this week


The U.S. Food and Drug Administration (FDA) will allow fully vaccinated Americans to ‘mix and match’ COVID-19 vaccines and booster shots.

The federal health agency is expected to approved extra doses for the Moderna and Johnson & Johnson immunizations this week.

But officials will also authorize people to receive a booster made by a company that is different than the one that made the vaccine they initially received, according to The New York Times.

It comes after researchers from the National Institutes of Health (NIH) presented data at an FDA advisory committee meeting on Friday showing people who got Johnson & Johnson’s Covid vaccine had higher antibody levels if they get a Pfizer-BioNTech or Moderna booster shot.

Previously, the FDA and the Centers for Disease Control and Prevention (CDC) had warned Americans not to mix and match shots from any of the three vaccine manufacturers.

But it seems attitudes have changed after a new NIH report found that people who got J&J’s COVID-19 vaccine had higher antibody levels if their booster shot was from Pfizer or Moderna.

The report found that when recipients of the one-shot J&J vaccine received a second dose, their antibody levels increased four-fold over two weeks.

Comparatively, when they received a Moderna booster, their antibody levels spiked 76-fold over the same time period. 

A booster shot of the Pfizer vaccine also raised antibody levels 45-fold over the course of two weeks – higher than the J&J shot, but not as high as the Moderna shot.

What’s more, the Moderna booster was also found to raise antibody levels higher in Pfizer recipients. 

Americans who received two doses of the Pfizer saw their antibody levels increase 21-fold after a third Pfizer shot.

But those given the Moderna booster had antibody levels raised 32-fold over the span of 14 days.

This is a breaking news story and will be updated.
