Expert at Sheba Medical Center says jab raises COVID antibody levels, but there are ‘still a lot of infections’ among those who received it
Nearly a month after Sheba Medical Center launched a landmark study to test the efficacy of a fourth COVID shot, the hospital said Monday that this fourth booster was only partially effective in protecting against the Omicron strain.
“The vaccine, which was very effective against the previous strains, is less effective against the Omicron strain,” Prof. Gili Regev-Yochay, a lead researcher in the experiment said.
“We see an increase in antibodies, higher than after the third dose,” Regev-Yochay said. “However, we see many infected with Omicron who received the fourth dose. Granted, a bit less than in the control group, but still a lot of infections,” she added.
“The bottom line is that the vaccine is excellent against the Alpha and Delta [variants], for Omicron it’s not good enough,” she said.
HERE’S THE UNSURPRISING SHOCKER
Prime Minister Naftali Bennett has pushed ahead with expanding Israel’s fourth dose program, despite the lack of data.
