Pfizer said that tweaking its vaccine to better target the omicron variant is safe and works — just days before regulators debate whether to offer Americans updated booster shots this fall.
New research out of New York found the protection of the vaccine against infection in kids ages 5 to 11 dropped from 68% to 12%.
The move to shorten the Pfizer booster interval comes as the U.S. shatters daily case records. The recommended interval for those who received Moderna or Johnson & Johnson vaccines has not changed.
The FDA on Friday granted emergency use authorization for the Pfizer-BioNTech and Moderna booster shots. The boosters have already been available for people 65 and older and to high-risk adults.
Kids ages 5 to 11 will soon be able to get Pfizer's low-dose COVID vaccine. CDC director Rochelle Walensky agreed with a unanimous decision of a team of advisers that the benefits outweigh the risks.
The agency acted after an independent panel of scientists strongly supported the move. Kids could start getting vaccinated within the week.
Should people who get a COVID booster get a different vaccine from their original shot? The results of a highly anticipated study suggest that in some cases the answer may be yes.

The FDA announced the Pfizer vaccine is the first in the U.S. that is now fully approved. Here's what that means for vaccine mandates and convincing vaccine-hesitant people to get vaccinated.
If all goes to plan, Americans who got Pfizer or Moderna shots can get a third dose eight months after their last jab. Here's why health officials think you'll need one.
A COVID-19 vaccine for children younger than 12 is not yet available, but research is well underway and the first shot for some kids in this age group is expected in the fall, doctors say.

Nope, they won't put a microchip in you. And the side effects usually aren't that bad. And if you want to get your HPV shot at the same time, that totally works. Read on for these and more answers.
Health officials are investigating reports of mostly mild, temporary and treatable heart inflammation that may or may not be causally linked to vaccination with an mRNA vaccine against COVID-19.
Instead of putting genetic instructions into people whose cells then make a viral protein, the vaccines from Novavax, Medicago and Sanofi carry a spike protein payload.
