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.
Faced with a slow, chaotic vaccine rollout and ever-rising Covid-19 cases, President Biden has an ambitious plan: to administer 100 million doses of the coronavirus vaccine in his first 100 days in office. Since the vaccines became publicly available in mid-December, 16.5 million shots have made their way into the arms of Americans, an average of 447,000 doses per day. Mr. Biden’s goal of more than doubling this rate can be achieved if the United States implements a vaccination campaign that treats Covid-19 more like an act of bioterrorism and less like the seasonal flu.
