A group of British doctors have written to England’s chief medical officer to tell him to cut the gap between doses of the Pfizer and BioNTech vaccine to six weeks from up to 12, Reuters reported.
Britain is prioritising giving first doses of Covid-19 vaccine, allowing up to 12 weeks before a second dose, to give the maximum number of people some initial protection.
But Pfizer and BioNTech have warned they have no evidence their vaccine would continue to be protective if the second dose is given more than 21 days after the first.
