Coronavirus update - NO MORE RESTRICTIONS

Re: Coronavirus update

They compare it to a placebo group.

The placebo group is not relavent to the question.
They can say that people in the olacebo group got severe syptoms, I agree. But that is not what they said.
They said as I quoted: It is 85% effective in peventing severe symptoms. If sypmtoms are prevented how can they say that a person would, without the vaccine have had severe symptoms? It's nonsense.

85% effective compared to a placebo group. That's what the number means.

It isn't nonsense it's how it's always done

It's a statistic against the placebo group not an actual figure, that's how efficacy is calculated at least until they have psychics in the teams assessing it.

I get the % figure, I understand it, it is the remark about severe symptoms that puzzles. If it works then people don't get severe symptoms and if it doesn't they do. But if it works how can they tell that a paerson would have got mild or severe symptoms? That's all.

I don't think you get it.

100 people in the trial get covid. 5 are in the vaccine group, 95 are in the placebo group. So the vaccine is about 95% effective.

1-(5/95) =0.947

Repeat.for those with severe symptoms.

Re: Coronavirus update

Vaccines aren’t 100% effective if that’s what you mean by work.

I can break it down for you if you like:

200 people in a test, 100 get there vaccine, 100 don’t.

Let’s say in the placebo group 50 people test positive for Covid while in the vaccine group 20 people do.

That means it has 60% efficacy.

Then out of the 50 people who tested positive in the placebo group 10 have severe symptoms but in the vaccine group only 2 have severe symptoms.

That means it’s 80% effective against severe Covid.

That’s what they mean. They don’t literally mean that one person would definitely have got severe symptoms, just by the efficacy of the vaccine you can extrapolate it.

NB- my %s aren’t correct

How do you survive wit incorrect %s. It must keep you awake at night.
Yes OK I see your point, perhaps it was just the way it was put.

More important is how do I upload pictures and gifs on here? I tried all ways but none work

Was there actually any change in the rules today from our esteemed leader?

I always have a look at the chart on this page which shows the rates per 100k for each district. Most of the time, Merthyr and RCT have been around the top, but I’m pleased to see them both in relegation trouble this week!

No wonder you've been keeping a low profile!

Seriously, it is good news all round. Touch wood, we have been lucky down here in Pembrokeshire although even here over 3000 have sadly died.

3000??

Re: Coronavirus update

3000??

I think he's a bit confused there, there have been 3000 cases in Pembrokeshire, not deaths.
