What's Going on With Novavax?

Meg Urry: Pfizer closed out 2022 with $100 billion in revenue. She says it's remarkable how much money was generated from COVID products. The current US supply of Novavax will expire at the end of February and won't receive shelf life extensions, she says. Urry: There are doses out there that had a nine-month shelf life. They are expiring. It doesn't sound like they're going to put out a bivalent now to BA5 and the original, which is what the mRNA vaccine bivalents are.
