Israeli hospital to test fourth coronavirus vaccine shot as Omicron spreads
- The trial will help gauge whether a second booster jab is necessary nationwide
- Prime Minister Naftali Bennett tests negative for Covid-19, but is self-isolating after his 14-year-old daughter was infected
Sheba Medical Centre near Tel Aviv said its trial would shed light on the efficacy of a fourth dose and help decision-makers set health policy in Israel and abroad.
Israel has reported 1,118 confirmed cases of the fast-spreading Omicron coronavirus variant, with the number of people infected by it doubling every two days.
A Health Ministry panel of experts has recommended offering a fourth dose of the Pfizer /BioNTech vaccine to Israelis aged 60 and over who received a booster shot at least four months ago.
But final approval by the ministry’s director general is still pending amid public debate as to whether sufficient scientific information is available to justify a new booster drive.
Sheba Medical Centre did not say how long its trial would last.
“We will examine the fourth dose’s effect on the level of antibodies and morbidity and we will gauge its safety,” it quoted Gili Regev-Yochay, the study’s director, as saying.
“We will understand whether it is worthwhile to administer a fourth shot, and to whom.”
The 150 Sheba medical workers taking part in the trial, which the hospital said had received Health Ministry approval, got booster shots no later than August 20.
Separately, Israeli Prime Minister Naftali Bennett’s office said he tested negative on Sunday for Covid-19 after his 14-year-old daughter was infected.
It said he would self-isolate.
