The fastest country to roll out vaccinations a year ago, Israel last month started offering a fourth shot - also known as a second booster - to its most vulnerable and high-risk groups. It has held off on expanding the offer to the wider population.
A preliminary study published by Israel's Sheba Medical Center on Monday found that the fourth shot increases antibodies to even higher levels than the third but "probably" not enough to fend off the highly transmissible Omicron.
