Pfizer Inc and Moderna Inc said on Tuesday (June 28) they will be ready with Covid-19 vaccines designed to combat the BA.1 Omicron variant that was dominant last winter earlier than those designed to target currently dominant subvariants.
Moderna said it would be ready with a "couple of hundred million" of bivalent vaccines designed to combat BA.1 by September, but it would be late October or early November if the vaccine maker needed to design a vaccine to combat the currently dominant BA.4 and BA.5 subvariants.
Pfizer said it has a significant amount of BA.1 vaccine produced already and is preparing to produce a large amount of vaccine against BA.4 and BA.5 subvariants. It said either vaccine could be ready for an early October rollout.
