Pfizer said two doses 3 weeks apart to have 90% + immunity.

Not one dose 12 weeks apart, if one dose gave v high immunity, they'd have settled for that.

I am amazed that the Govt decided, with zero trials & based on completely different vaccines, to have a 12 week gap.

Agree. You've been given a vaccine that takes two doses to become effective. You get given one and then complain it hasnt worked. What do you think will happen? Of course it doesnt work. And there were no studies done to see what would happen with only one dose. So all these figures being thrown around 33% or 90% efficacy have no basis. No trials were done where recipients only recieved one dose so they don't know effective it is.

Have they published this to stop people in the UK who have had their first dose becoming complacent?

No trials were done where recipients only recieved one dose so they don't know effective it is

Not with Pfizer, no. Oxford has data for a 12 week dosing schedule though

It’s astonishing that this government are pushing ahead with a strategy for which there is no scientific data at all.

It’s just bad science.

Yes I get that Pfizer have to state that it wasn’t designed that way, but other experts who know about vaccines and are not in government, think it’s ok. They know more than me or The Sun.

Sadly I am not amazed. I expected it, it's in keeping with the way things are done here. They can't cope with the expense and time it takes to do things properly for the population, so nothing ever gets done properly. I read a few days ago that they are now hinting it could be even longer than 12 weeks between doses.

The AstraZeneca is not an mRNA vaccine.

You can’t just guess that one technology will work roughly the same as another.

It was on the news this morning that it's 33% after a few days but rises to (can't remember exact figure) 80% after 12 weeks then you have the second dose??

I think I would rather trust what Pfizer says than any amount of experts in whose best interests it is to agree with the government's line, even if they don't work for them.

Its almost as Pfizer said ....

"No problem, we never intended for our vaccine to be used in this way and we've zero data on what happens if it is but your experts, who never worked with us on the design or the trials we ran, clearly know far more than we do... go for it!"

But they didn't...... i think its wise to stick with what these Pfizer experts say.

Ha ha in which trial did that happen in?

Been less than 4 weeks since the first Pfizer dose was administered.

So, as been said above, nearly 90% protection from SEVERE Covid after the 1st Pfizer dose and 95% after the 2nd dose.

If anyone cares to read the original summary / guidance notes written by Pfizer-Biontec for the US FDA approval should simply Google 'fda briefing document pfizer vaccine',

Lots of useful info!

That is far more comforting as are other posters' explanations. I didn't realise the effectiveness was against severe Covid rather than Covid per se. Every day is a school day. Thank you to posters for their knowledge.

You can’t be an expert in a vaccine type that has never been rolled out in the population before. You could be an expert in developing it.

And the experts in developing it say that they have ‘no data’ on 12 weeks wait.

Which means that literally nobody knows what the effect will be.

That was to @Benjispruce2

DH is an intensive care Dr and the understanding is it’s in the 60% bracket. No that’s not ideal but not as bad as the sun are making out.

I would not trust the sun as far as I could throw them, they’re really not helping the moral of the country by printing this stuff.

People don't want useful information.

They want to be outraged and pessimistic, and rant against the government.

Vaccine + Mask + Social Distancing + Good Ventilation. That’s the key to protecting yourself from the virus. You can’t just have the vaccine without any other precautions then swan around like you’re immune. You’re not.

Well said.

Equally you are not safe really just doing the latter 3 of your list without the vaccine as an under-50 - the statistics on who is in critical care or even just requiring hospitalisation just don't support that any more.

Which is presumably why we in this country have not been provided with any ongoing in-depth data compared with many other countries. It seems we don't care to know!

The DM is as bad as the Sun - loads of interviews with people over 60 taking off their masks and visors going on about going to the pub/to France/hairdressers. Life after lockdown will be very different with all the elderly and vulnerable vaccinated, but a large section of under-50s unvaccinated and still requiring hospitalisation.

Surely whitty should resign though didn't he and the other cmo sanction this?

@Motorina
Exactly. Which is presumably why we in this country have not been provided with the same indepth, granular stats that many other countries have received. It seems it's not necessarily a case of we don't understand, we just don't care to know (with 'we' referring to the general population)!

That goes against all the official testing which was around 70%. I don't understand how the Israelis can come up with conflicting evidence.

I was talking to a medical scientist today who has been looking at the data from Israel and he said it seems that some of the infections were contracted in the first week or so when you wouldn't expect immunity to be as high as it will be eventually. Which is why people should still be very careful after having the vaccine.
So don't get downhearted by this story!
