Israel, in allocating its initial supplies of COVID-19 vaccines, decided not to vaccinate “certified recovered COVID-19 patients.”
U.S. health authorities have decided otherwise, advising all eligible people to get the vaccine whether or not they have previously tested positive for the virus that causes COVID-19. Health officials cite the possibility of re-infection and uncertainty about the duration of any immunity. Recent studies suggest that those who have recovered from the virus may need only one dose of the vaccine to achieve future protection. Both studies are awaiting peer review.
Israel is leading the world in its vaccination rollout. As of Feb. 3, Israel had fully vaccinated 20.9% of its population and partially vaccinated another 36.4%. The U.S. had fully vaccinated 1.8% of its population and partially vaccinated another 8%.
