Deutsche Welle interview on single dose: https://www.youtube.com/watch?v=LIFqzDQJHuw

Its more like an absolute desperation panic measure as London cases are rising and one which risks giving nobody any protection and likely wasting millions of doses of vaccine.
Pfizer said in a statement that there are "no data" to demonstrate that a single dose of its coronavirus vaccine will provide protection from infection after 21 days.

Pfizer confirmed in response that although some protection appears to begin as early as 12 days after the first dose, two doses of the vaccine — separated by three weeks — is the only regimen that proved to be 95% effective in Phase 3 trials.

Ultimately the UK decision is about as anti-scientific as its possible to get.
Stepping massively outside the actually trialled protocol with literally not a shred of data to suggest it'll work at all and worse, no data to show it wont be completely and utterly ineffective.

Whatever committee advised this are now completely unhinged and dangerous. There is nothing at all to suggest this will do anything except make things worse.

Rather than giving the most vulnerable 90% protection we could be giving the most vulnerable 0% protection.

There's no data to show *any protection* after 21 days as its not in the trials and no data to show a 2nd dose 12 weeks later provides *any protection* at all for Pfizer.

Its perfectly feasible the first dose triggers a weak immune response which is quickly forgotten providing no long term protection and the 2nd dose then does the same.

Also, stop calling it "immunity". Its NOT immunity. You don't understand the word.
This is 100% symptom reduction. We have no data to suggest there's any immunity at all and Pfizer said there wont be until at least after Q1 2020.

This surely has to be the final nail in the coffin for SAGE and all the related committees. Making up their own stuff despite literally no data, and against MHRA approval and directly against manufacturers advice and peer review.
They've gone totally rogue.

Rather than giving the most vulnerable 90% protection we could be giving the most vulnerable 0% protection.

I hear what you say, perhaps you do not have the data Splatt? You have to see the press conference.~ 22 minutes in.

The data shared with us, and I’m not sure is entirely in the public domain, calculated the vaccine efficacy between day 22 of dose one, to the time of dose two being given, and the figure is around 70%,”

Said Wei Shen Lim, chair for COVID-19 immunisation of the Joint Committee on Vaccination and Immunisation. Note their word Splatt, Immunisation so please quit nagging me about it.

I expect they will be monitoring this over the next few weeks, if protection drops off. The questions you ask are mentioned at minute 26, for what it is worth.
Transmission question answered at minute 30. not enough data yet. so like I said before , don't bet the farm on it.

12 week interval questions answered at minute 32...

It is what it is. cheers, Splatt, I think they cover it all in the press conference.

We've had anti-science from the beginning so I'm not surprised by this development. Let's hope it is finally a wake up call for those believers in the covidian cult that are redeemable.
