Prime Minister Naftali Bennett has paid a visit to Sheba-Tel Hashomer Medical Center, where he was presented with the results of the first-ever research study into a fourth COVID vaccine shot.

The study was led by Prof. Gili Regev.

"The Omicron storm is growing and spreading," Bennett said. "This first study has shown that within a week of receiving a fourth vaccine dose, the number of antibodies in the blood rises five-fold. The fourth shot is safe and it works," the Prime Minister concluded.
