Israel considers fourth coronavirus vaccine dose

Prime Minister Naftali Bennett said Israel will consider a fourth COVID-19 vaccine "for populations at risk," in an attempt to combat the new omicron variant. Last month, Israel barred entry to foreign nationals and the use of controversial technology for contact tracing as part of its efforts to clamp down on the new variant.

Israel's Health Ministry announced 55 cases of omicron on Saturday, raising fears of a possible surge in infections. The country launched one of the world's first and most successful vaccination campaigns late last year, and more than 4.1 million people have now received a booster shot.
