US statistics

[TotorosCatBus]

Just under 50% vaccinated
99.5% deaths unvaccinated people
97% hospitalizations unvaccinated people
Delta is the dominant strain but not as high as in UK

In England
60% of hospitalizations aren't double jabbed (so 40% have had one or two jabs)

Is this difference because many over 40s in England were vaccinated with AZ rather than mRNA vaccines?

Makes me wonder which is the reliable data because it just does not add up.

I’m wondering too. Though the data suggests there’s not much between AZ and Pfizer after both jabs in terms of hospitalisations and deaths. Maybe it will be updated soon as we have more info. I know AZ are working on boosters at the moment.

We do know have real time data now of thousands more people so if the efficacy has changed (and I hope it hasn’t) this should be updated.

I suspect it's a difference in the way they and we count "hospitalisation".

Everything I've read about AZ suggests it's as effective as pfizer but takes longer to reach full efficacy.

That's all still being processed. I have a vague memory of someone explaining how they are currently looking at that data to inform booster development.

That was just this week, so there should be some preliminary findings in the next few days.

There isn't that much info on AZ, I will look for the table that says not enough info...worrying

Recent study in Canada of AZ and explanation here.

"Real-world data out of Canada shows just ONE dose of AstraZeneca’s vaccine is highly effective against preventing hospitalization and/or death caused by SARS-CoV-2 VOCs.

•Alpha (B.1.1.7): 90%
•Delta (B.1.617.2): 87%
•Gamma (P.1): 82%
•Beta (B.1.351): 82%"

That could just mean the data is too homogenous and some of the study criteria haven't been met. Which could be indicative of AZ being highly effective, as the Canadian data seems to suggest.

I think one jab is a bit useless against delta and we have a LOT of people with just one as we spaced them out so much

It’s not like for like. In the US they did jabs with a break of 3 weeks, so the ‘half jabbed’ crowd doesn’t really exist.

Of your 40%, how many are half jabbed only?

The number of people in the US that are ending up in the ICU is almost double that of the UK as a proportion of the population.

So the higher proportion of vaccinated adults in the UK, especially vaccinated older and vulnerable adults, means that the number of people ending in ICU is halved but the proportion of these that are vaccinated is naturally higher.

What we need to see is the total number of hospitalisations and ICU admissions, and how old are these vaccinated and unvaccinated patients.

My guess is it will be the very old and/or vulnerable vaccinated adults vs young healthy unvaccinated. A 50/50 proportion basically means if you're an old vulnerable adult and you get the vaccine, your risk of hospital or ICU admission is now equal to that of a young healthy unvaccinated adult.

The US simply has more unvaccinated people who are at higher risk of hospitalisation, so they dominate the figures, it's not difference in vaccination effectiveness, the indications so far is that all the (UK and US authorised) vaccines are similarly effective against hospitalisation.

Don’t the US have a lower percentage of older people vaccinated? Older people are still the most likely to be hospitalised/die. Even more so if they haven’t been vaccinated.

I thought the USA most have been given the one dose Janssen vaccine, so they would be more protected than having to wait for the second dose.

I don't know. It's something that Vallance mentioned in a press conference recently.

Thanks for the replies. I'd not considered that the percentage of each group taking the vaccine might be different in the US.

One way of getting an idea would be to have a vaccine breakdown for the vaccinated people in UK hospitals.

Which vaccines did they have?

Do we regard 'hospitalisations' as the same thing? Our 40% vaccinated 'hospitalisations' could be in for an appendectomy and have tested positive for Covid ......doesn't mean that they are being treated for Covid

@sirfredfredgeorge

The US simply has more unvaccinated people who are at higher risk of hospitalisation, so they dominate the figures, it's not difference in vaccination effectiveness, the indications so far is that all the (UK and US authorised) vaccines are similarly effective against hospitalisation.

But also the people who are fully jabbed are still sometimes getting breakthrough infections. But they're rarely getting ill enough to need hospital.

That data is from June when delta wasn't very prevalent in the US.

No the data is also for July, when Delta became the dominant strain.

What we need to see is the total number of hospitalisations and ICU admissions, and how old are these vaccinated and unvaccinated patients.

And - we also need to know which vaccine the fully vaccinated (in UK hospital) were given.

What's the issue with giving us this information?

Useful article here - www.irishtimes.com/life-and-style/health-family/if-the-covid-vaccines-are-working-why-are-double-jabbed-people-being-hospitalised-1.4628503

Sadly I have wondered what happens to poor people in the USA who have no medical coverage or are frightened as they are considered illegal
We also have an aging population & a single health system which make sit easier to do more accurate stats
At the beginning it was unwisely (criminally?) decided to send old people back to nursing homes & the number of people who died there was appalling
USA is an enormous country where the poor disappear & are uncounted & there may also be a pressure not to count the casualties of covid amongst certain other communities (religious groups etc & I am talking about some of the Christian fundamentalists)

Thank you that article does explain things well.

I was thinking about this statistic and wondering if I was kidding myself how well protected I am (double AZ) but I feel reassured that I was forgetting a lot of other factors. It's a statistic that the anti-vaxxers online have been loving.

re double jabbed - many are extremely vulnerable with issues with their immunity systems ie blood/ chemo & extreme old age (it was mentioned somewhere)
