The CEO of Moderna says that booster shots will likely become less effective with time. As a result, in the next few months, some people may need a fourth shot.
Stephane Bancel, the CEO of Moderna, said that those who received their booster shot last fall will likely be safe for winter. However, he revealed that the efficacy of the boosters may drop after that.
“I will be surprised when we get that data in the coming weeks that it’s holding nicely over time – I would expect that it’s not going to hold great,” Bancel said in an interview with Goldman Sachs.
Barcel pointed out that the same thing happened with the first two doses. The shots lost efficacy during the winter months, as infections surged. With more people staying indoors due to cold, a surge in infections is likely.
But that’s not the worst of his predictions. He also added that more booster shots may be needed in the fall of 2022 “and forward.”
“We have been saying that we believe this virus is not going away. We’re going to have to live with it,” he said.
The world currently experiencing a surge in infections due to the Omicron variant. The U.S. is now seeing an average of 574,000 cases daily.
So far, the data shows that Omicron is more transmissible but less dangerous than past strains. However, that could also change, Bancel said.
“What is totally impossible to predict, is there a new mutation coming in a day, a week, three months that is worse in terms of severity of disease,” the CEO of Moderna warned.
