After giving almost unanimous support to US booster shot guidance a year ago, health experts are now split over when people should get them and who will actually benefit.

Bloomberg polled 13 vaccine specialists, infectious disease doctors and public health experts on the latest Centers for Disease Control and Prevention recommendations about getting the new booster shots from Moderna Inc. and the partnership of Pfizer Inc. and BioNtech SE. Not even half of those surveyed fully endorsed the CDC’s latest guidance. Some said people should consider waiting longer than the two months recommended between doses, while others thought only higher-risk people should get another shot right now.
