The U.S. is one step closer to having new COVID-19 booster shots available as soon as this fall.
On Monday, the drugmakers Pfizer and BioNTech announced that they've asked the Food and Drug Administration to authorize an updated version of their COVID-19 vaccine — this one designed specifically to target the omicron subvariants that are dominant in the U.S.
More than 90% of cases are caused by the BA.4 and BA.5 subvariants, which took off this summer, but the vaccines being used were designed for the original coronavirus strain from several years ago.
Pfizer and BioNTech said they have submitted pre-clinical data on vaccine efficacy to the FDA, but did not share the data publicly.
The new "bivalent" booster — meaning it's a mix of two versions of the vaccine — will target both the original coronavirus strain and the BA.4 and BA.5 omicron subvariants.
If the vaccine is authorized by the FDA, distribution could start "immediately" to help the country prepare for potential fall and winter surges of the coronavirus, Pfizer CEO Albert Bourla said in a statement.
