The fourth dose of the COVID-19 vaccine boosts antibodies fivefold a week after the shot is administered, Prime Minister Naftali Bennett said Tuesday, citing preliminary findings of an Israeli study.

Dr. Gili Regev-Yochay, who is leading the study at Sheba Medical Center in Tel Hashomer, told Bennett the fivefold increase in antibodies indicates that the vaccine works and provides protection against serious complications. In addition, the new booster appears to have a safety profile similar to the previous ones, she said.
