Israel said on Sunday it will begin offering a booster shot of Pfizer Inc's vaccine to adults with weak immune systems but it was still weighing whether a third round of shots should be given to the general public.
The rapid spread of the Delta variant has sent vaccination rates in Israel back up as new infections have risen over the past month from single digits to around 450 a day, and the country has moved to fast-track its next Pfizer shipment.
Health Minister Nitzan Horowitz said that effective immediately, adults with impaired immune systems who had received two doses of the Pfizer vaccine could get a booster shot, with a decision pending on wider distribution.
