Yesterday Thursday, the ministry's director general Nachman Ash approved the administration of a fourth dose of the vaccine for people with weakened immune systems, and the administration of these doses begins today.
An Israeli hospital administered a fourth dose to a group of health workers Monday as part of the first, large study of whether a second round of booster doses would help limit the spread of the Omicron variant.[BR]Results are expected within two weeks.
Last week, a panel of Health Ministry experts recommended that Israel begin administering a fourth dose of Pfizer's vaccine to health workers and those over 60 or immunocompromised.
Israel is the fastest country to release the initial vaccines a year ago and became one of the first to offer booster doses having observed that immunity wanes over time.
Its policy on booster doses is being studied by other countries, including the US, which are considering when to offer booster doses.
