One Pfizer vaccination 52% effective after 12 days (according to an article in El País in English from 13 January 2021)

thewanderer said:
The 52% figure that keeps getting quotes here is the average efficacy from the the first jab. Including the 12 days where there is almost zero pritection. After about 12-14 days this is well over 80%. Plus let's not forget the vaccines have a near 100% chance of preventing severe covid.

There is something wrong with that sentence unless I misunderstand it. Are you saying the vaccine is 80% effective in stopping the person catching covid but if they do catch it they are 100% protected against a severe case of covid? Not sure that talies with what I read.

I am not sure of the accuracy of the assumption that one shot stops you being hospitalised or dying.

That's what all the 'experts' were saying on TV. To their knowledge not ONE reported case of someone taking the vaccine, becoming infected and ending up in hospital.

Not sure that translates to 100% efficiency though given the small numbers and more importantly the small amount if time. I hope its the case, but if it is, why the second vaccination? That doesn't make any sense.

That isn't right Molten, recently a nurse, in wales, contracted covid 3 weeks after her first jab, but before the second and her symptoms were quite severe.

It's really quite f=difficult to get a definitive answer to how effective a single dose of the pfizer vaccine actually is. Obvioulsy the story above is not proof one way or the other, we have vaccinated 3 million and some are bound to contract the virus after the vaccination.##


I looked at the Pfizer site that, I think, roofie linked to and couldn't get a definitive answer to how much protection you get after one dose.
 
Remember in the Pfizer trials the 52.4% efficacy after the 1st dose of Pfizer was an AVERAGE, so some will be less immune. I heard a member of Sage on Jeremy Vine show last week repeating the govt mantra that 1st dose gave 90% protection and implying this was for everybody, which is not what it says in the Pfizer trial 3 outcomes. The truth is being worryingly massaged for political ends. All this just not being challenged properly in MSM or by other political parties

No, it is the average efficacy from day 1 of the first jab, which takes about 12-14 days-ish for your immune system to react to giving the near 90% efficacy. The member of SAGE was not parroting the government line but giving you the facts.

Did she end up in hospital? NO she did not.

Did she end up in hospital?
 
Laughing said:
That's not what I said, why the aggression? It doesn't add anything, the nurse describes her symptoms as severe I would guess she would know.

As, it was answered - she didn't end up in hospital. That's what I was meaning - you can still get it, and it might be bad, but you won't need to go to hospital.

As it is possible we can still transmit the virus when vaccinated it maybe is purely to stop us getting hospitalised.

And sorry to put a downer on things but surely if the vaccine doesn't stop transmission we will have this virus for life? It will mutate, get around the vaccines, we'll have more lockdowns, it will never end.

I just answered that Molten, I used the nurses description of her condition so it is relevant. She wasn't hospitalised, but she was relatively young and without the vaccine she probably wouldn't have been hospitalised either.

The vaccine is a good thing, of that there is no debate. The decision to delay the second vaccination is the debate here and I think it is probably wrong and the nurse is some evidence of that.

There is a doctor in Chicago who died after vaccination, at the moment we don't know why and it is probably completely unrelated to covid and/or the vaccine but there is still evidence to be gathered before we can say the Pfizer vaccine is 90% effective after 1 shot and that efficacy lasts for the 3 month gap until the booster shot.

There is evidence coming from other countries that the one shot efficacy is not 90%.

we may well have it for ever, but plenty of viruses have been almost eradicated. The flu is an example of a virus that mutates very quickly, and unfortnately early evidence suggests that covid will continue to mutate quickly.

That said, covid may well become a seasonal disease that kills folk in the same way that flu does and the vaccine is available to mitigate that.

We can just hope that this is the last lockdown. It goes to show with these mutations that there is a very good argument to help poorer countries get vaccinated too so were can reduce the chances of mutations.

You're not wrong, it is so infectious now that if it exists anywhere it will spread.
