New Covid Vaccines Are Coming. Here’s What to Know.
The F.D.A. approved one vaccine from Pfizer and one from Moderna. Representatives from the drug companies said that their shots were ready to ship immediately after approval.
Both vaccines target KP.2, a strain of the coronavirus that started to spread widely this spring. The variants that are most prevalent in the United States right now are very similar to KP.2, and so the vaccines should protect against them.
The biotechnology company Novavax is waiting for the F.D.A. to authorize its retooled vaccine, which will target JN.1, a variant that is also close to the strains circulating widely now.
