Moderna CEO says 4th COVID dose may be needed next fall

(HealthDay)—A fourth COVID shot may be needed for most people by next fall because of what will likely be waning immunity, Moderna CEO Stephane Bancel said Thursday.

While the booster that millions of Americans received this past fall should hold strong through this winter's Omicron surge, Bancel said the efficacy of boosters will probably decline over the course of several months, similar to what happened with the first two doses.

"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 of the booster shots during an interview with Goldman Sachs during its healthcare CEO conference, CNBC reported.
