Israeli hospital launches first test of second Covid-19 booster

An Israeli hospital launched the first test of second Covid-19 booster shots on Monday.

An Israeli hospital administered fourth Covid-19 vaccine doses to a test group of health workers on Monday, in what it called the first major study into whether a second round of boosters will help contend with the fast-spreading Omicron variant.

Results of the trial, likely to be closely watched internationally, will be submitted to Israel's Health Ministry in about two weeks, said a spokesperson for Sheba Medical Centre near Tel Aviv.
