Also, I think there are ethical considerations. The GMC ought to be stepping into this debate. Those already vaccinated gave their consent on the basis of 2 doses 3 weeks apart, that being the regimen that was shown to work. Those people who received the first dose on that basis should receive the second dose as planned. Anyone who is yet to have their first dose should be consented according to any new policy and the evidence for that should be discussed.
If there is good evidence to show it works well when given 12 weeks apart then make it public. This policy is a gamble. If there is a gap in manufacturing capacity for instance and they don’t have enough 2nd doses to go around. If it doesn’t work then they will have wasted all those first doses and have to do it again. I’d like to see the evidence for it.
