The Sheba Medical Center at Tel Hashomer is slated to begin a study tomorrow on the efficacy of administering a fourth dose of the COVID vaccine.
The hospital says that the study will constitute giving 6,000 individuals — including 150 medical staff — a fourth shot.
The study, said to be the first of its kind in the world, is being carried out in conjunction with the Health Ministry, and has been approved by the government’s senior panel on human medical trials.
“This study will test the effect of the fourth vaccine dose on the level of antibodies, on preventing contagion, and check its safety,” says Sheba’s Prof. Gili Regev-Yochay. “This study is expected to shed light on the additional benefit of giving a fourth dose, and lead us to understand whether and to whom it is worth giving a fourth dose.”
