If approved, this would be the second booster shot Moderna has issued for people ages 18 and up.
Now, both the Pfizer and the Moderna booster shots can be given five months after the second dose of vaccine — down from six months.
The Moderna vaccine's ability to shield against infection drops sharply when tested on the omicron variant. But getting a booster pumps the protection back up again, new research suggests.
The agency acted after an independent panel of scientists strongly supported the move. Kids could start getting vaccinated within the week.
Moderna says a study in kids 6 to 11 found two doses of the company's COVID-19 vaccine given 28 days apart produced a strong antibody response.
CDC Director Rochelle Walensky also endorsed a mix-and-match approach to boosters that would be flexible for patients and health care providers.
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 COVID-19 vaccines continue to provide powerful protection, even against the delta variant, the CDC said. It also found that vaccinated people were 10 times less likely to be hospitalized.
Moderna submitted data from 344 volunteers who got a third shot of the vaccine six months after their first two doses. The additional shot significantly boosted immunity, the company said.
The health ministry said contamination was reported from multiple vaccination sites. The news raises concern of a supply shortage as Japan tries to accelerate vaccinations amid a surge in cases.
