Moderna CEO predicts existing COVID vaccines less effective against Omicron
… Moderna … in all likelihood, would prove to be less effective against the new Omicron variant
… “There is no world, I think, where [the effectiveness] is the same level
… we had with Delta,”
… “I think it’s going to be a material drop,”
… “I just don’t know how much because we need to wait for the data”
… “But all the scientists I’ve talked to
… are like ‘this is not going to be good,’”
… Pfizer … “we need to create a new vaccine,”
