Israel recommends FOURTH Covid jab to all adults to triple protection against severe illness

Health officials in Israel have recommended a fourth Covid jab to all adults, citing research showing that it can triple protection against severe illness.

The advisory committee said a fourth dose provides three to five times the level of protection against serious disease and can double the protection against infection compared to three doses.

Israel is already offering a second booster to everyone over 60 and those at high risk as it struggles to contain a wave of infections fuelled by the Omicron variant.
