LONDON: 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.
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.The British Medical Association said in a statement emailed on Saturday that it has written to the Chief Medical Officer for England Chris Whitty.
The BMA said it supports giving a second dose up to 42 days after the first dose, but that a longer gap is not in line with World Health Organization guidance.It therefore urged the CMO to"urgently review the UK's current position of second doses after 12 weeks"."BMA members are also concerned that, given the unpredictability of supplies, there may not be any guarantees that second doses of the Pfizer vaccine will be available in 12 weeks’ time.
