A second booster jab brings antibodies to even higher levels but is not enough to prevent infection, according to the first-of-its-kind trial.
Moderna CEO Stephane Bancel on Thursday said people may need a fourth shot of the coronavirus vaccine in fall 2022,
The clinical trial involves 150 volunteers from the staff of a hospital near Tel Aviv who are at least four months removed from their third vaccine shot and have signs of waning antibodies.
