Fourth Covid booster enhances antibodies five-fold: Israeli study

Israel has become the first country to roll out the fourth dose of the Covid-19 vaccine to health workers and people aged 60 years old and those with weakened immune systems.

Jerusalem: Amid rising cases of Omicron, a preliminary study by Israeli researchers has shown that the fourth dose of Covid-19 vaccine boosts antibodies five-fold in just a week after the shot is administered, Prime Minister Naftali Bennett said on Tuesday.

Bennett spoke during a visit to the Sheba Medical Center, where Israel launched a trial of a second booster early last week, the Jerusalem Post reported.
