Israel’s coronavirus tsar has warned that a single dose of the Pfizer/BioNTech vaccine may be providing less protection than originally hoped, as the country reported a record 10,000 new Covid infections on Monday.

In remarks reported by Army Radio, Nachman Ash said a single dose appeared “less effective than we had thought”, and also lower than Pfizer had suggested.

By contrast, those who had received their second dose of the Pfizer vaccine had a six- to 12-fold increase in antibodies, according to data released by Sheba Medical Center in Tel Hashomer on Monday.
