Israeli medical workers receive Covid-19 vaccine at Ichilov hospital in the Israeli coastal city of Tel Aviv, on December 20, 2020. Israel has ordered 14 million doses of the vaccine -- covering seven million people, as two doses are required per person for optimal protection -- from Pfizer as well as US biotech firm Moderna. The vaccine will be rolled out at 10 hospitals and vaccination centres around Israel for healthcare workers from Sunday, according to the health ministry. AFP / JACK GUEZ
