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,”
