Doctors call for shorter gap between Pfizer Covid vaccine doses in UK
British Medical Association warns current 12-week wait could reduce effectiveness of the jab

No, it's really not. It's very clear why it's done. It's to get more people vaccinated and so give protection to more of the vulnerable groups. The only alternative is to give a smaller number of people more protection, and in the current situation the decision has been made that is not as effective in protecting more people. That might change, but currently it does make clinical sense.
And of course the BMA are going to argue that, that's their job, to represent the best interests of doctors, not to argue for the best clinical option for the population as a whole. You can't have GP surgeries making their own decisions over this, or the whole thing will be chaotic and unfair and will cause massive rows. People are already moaning about the different speeds areas are vaccinating, can you imagine if the surgery down the road started giving second jabs against advice when some people haven't had their first?
"The absence of any international support for the UK's approach is a cause of deep concern and risks undermining public and the profession's trust in the vaccination programme," the letter said.
WHO acknowledges that a number of countries face exceptional circumstances of vaccine supply constraints combined with a high disease burden. Some countries have therefore considered delaying the administration of the second dose to allow for a higher initial coverage. This is based on the observation that efficacy has been shown to start from day 12 after the first dose and reached about 89% between days 14 and 21, at the time when the second dose was given. No data on longer term efficacy for a single dose of the mRNA vaccine BNT162b2 currently exist, as the trial participants received 2 doses with an interval between doses in the trial ranging from 19 to 42 days. Of note, neutralizing antibody responses are modest after the first dose and increase substantially after the second dose.
Countries experiencing exceptional epidemiological circumstances may consider delaying for a short period the administration of the second dose as a pragmatic approach to maximizing the number of individuals benefiting from a first dose while vaccine supply continues to increase. WHO’s recommendation at present is that the interval between doses may be extended up to 42 days (6 weeks), on the basis of currently available clinical trial data. Should additional data become available on longer intervals between doses, revision of this recommendation will be considered. Countries should ensure that any such programme adjustments to dose intervals do not affect the likelihood of receiving the second dose.
I bet half the people now arguing it's wrong would be arguing the other way and we needed to protect more people with longer gaps if the government had stuck rigidly to the shorter gap between doses tbh.
They'll call whatever they do 'world beating' because they're fundamentally dishonest about everything but I think the vaccine plan has pretty major scientific support.Cos then, they get to be top of the tables. "We have vaccinated more people than anyone in the world."
I doubt it, given that the argument for the shorter gap is that that's what was tested and what we have evidence for.I bet half the people now arguing it's wrong would be arguing the other way and we needed to protect more people with longer gaps if the government had stuck rigidly to the shorter gap between doses tbh.
And I also note WHOs recommendations, whats the excuse for ignoring these?

These disgusting attempts to distort scientific principals have been noted.
don't be sillyFunny how covid has turned some anarchists into defenders of the government innit
It definitely takes world-beating levels of arrogance for the leaders whose strategy led to the highest death rate in the world and the spawning of a new COVID variant to decide to ignore scientific advice and press ahead with their own untested plan.

Why is it a pointless discussion now?It was a decision taken on scientific advice. Anyway this is a pointless discussion now, I'm out.
It's possible that both those decisions, to follow one piece of advice and ignore another, were taken for similar political reasons ie. prioritising days at work over an overall long term strategy. The whole vaccine thing gives me the willies since I found out it's not a sterilising vaccine. This is going to go on for decades.We rightly rounded on the government when they ignored the scientific advice from SAGE about locking down earlier, yet some are now rounding on them for accepting the scientific advice from JCVI.
But, well, this is urban.
