Another Jab? Israel Starts Fourth Covid Vaccine Dose Trial
(Bloomberg) -- A leading Israeli hospital has started what it says is the first formal clinical trial examining the safety and efficacy of a fourth dose of coronavirus vaccine.
Sheba Medical Center has begun to administer a fourth dose to 150 medical workers who received third doses before Aug. 20 and currently have a low antibody count, according to a statement from the hospital. The trial is being done in conjunction with Israel’s Health Ministry.
Prime Minister Naftali Bennett announced last week that the government would adopt the recommendation of a panel of experts to inoculate older adults and medical personnel with a fourth dose of Pfizer Inc.-BioNTech SE vaccine in a bid to shore up protection against the fast-spreading omicron variant.
However, a few days later, the Health Ministry said its director general had not yet decided whether to go ahead with the immunization drive. Some experts had questioned the wisdom of a fourth shot given the paucity of supporting data.
Initial data regarding safety will be available in a few days, said Professor Gili Regev-Yochay, who is spearheading the trial at Sheba.
