No it was for gladioli but its a genuine question so yeah of you have the answer that would be good. I realise it's a bit jumbled, am getting tired 😂 will try to find a link, but I thought I read that they wereeasurimg how many vaxxed versus unvaxxed had died but were doing so from the beginning of the rollout, so saying that during that time period more unvaxxed died, when that would obviously be the case since at the start hardly anyone was jabbed. Is that better?! I'm not looking for an argument at all by the way, it's a question, that's all, if they now have info that shows that more unvaccinated die than vaccinated that would be interesting. Although writing that I see there's a problem that now most are jabbed, so it would show more jabbed die.... Tired ramblings now!
That makes sense as a question:
So what they are looking at is proportions. The maths is easier with equal numbers but it's totally doable with uneven numbers too.
Essentially a much lower proportion of vaccinated people get COVID (and die of COVID) compared to the proportion of (age and sex matched) unvaccinated people.
In a mo I'll do an example with different numbers of people in each group: but the study trials for the vaccination approvals will have been done with equal numbers in each group. They then do whole of population assessments but you have more confounding factors in those (because of age and risk factors as discussed above, which are harder to control for when you review on a population basis).
Different numbers:
Let's imagine we've got 100,000 age and sex matched people. 90,000 have had the vaccine, 10,000 haven't.
Of the 10,000 people let's say, 1,000 get symptomatic COVID and 10 die.
Of the 90,000 people, 450 get symptomatic COVID (and in this example let's assume once you've got COVID your chance of dying is the same - in reality it is lower), and 5 die (rounding up).
Looking at the numbers straight up it might look like being vaccinated only halves your likelihood of Covid (1000 Vs 450). But the 1000 was out of 10,000 and the 450 was out of 90,000.
So in this example (which is just a set of numbers put in to show how the statistics work) you had a 1/10 chance of catching it if unvaccinated (1,000/10,000) Vs a 1/200 chance of catching it if you were vaccinated (450/90,000). So 20x lower.
That's just an example but it shows you how the calculations and the proportionality works even if you have different sized groups for vaccinated Vs unvaccinated people - it doesn't ruin or skew the study.
