Moderna CEO Stéphane Bancel has said Covid-19 vaccines are unlikely to be as effective against the Omicron variant of the coronavirus as they have been previously. "There is no world, I think, where (the effectiveness) is the same level . . .
we had with Delta," he told the Financial Times in an interview. "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.'" Vaccine resistance could lead to more sickness and hospitalisations and prolong the pandemic, and his comments triggered selling in growth-exposed assets like oil, stocks and the Australian dollar.
