the reason why more vaccinated people end up in Hospital than unvaccinated when more folks get vaccinated

this does NOT mean of course that vaccines don't work. (d'load the pdf link in comments below to more easily read detail)

here is another graphic derived from CDC weekly covid datasheets links below

this perhaps also helps to show as more folks get vaccinated, in proportion to the unvaccinated (top panel), the greater the numbers appear in the lower panel.(but the total will always be fewer than if more folks remain unvaccinated)

it's a difficult concept as more of us are now vaccinated and yet hospitalisations contain more vaccinated

here are some more useful graphics (thx SpookyHead!)

Simpson's paradox

and "absolute numbers [make] a mistake that’s known in statistics as a ‘base rate fallacy’: it ignores the fact that one group is much larger than the other" How do death rates from COVID-19 differ between people who are vaccinated and those who are not? "

Revisiting this thread December 2022

Please note the graphics & data in the second post above were saved more because they helped us understand at the time how vaccinated hospitalisations would eventually rise more than unvaxed as vaxed became the majority

 a good updated overview of the UK Covid data & timeline is here https://www.kingsfund.org.uk/publications/deaths-covid-19  which was last updated August 2022

Remember the CDC data in the 2nd post was from July in the year when Vaccines had had maybe 5 months of introduction, & were starting to really reduce serious illness in older people (>30 years of age probably) but it will be useful to see some of the latest updated data reviews. (see King's Fund Explainer linked above & here

Again the point we were studying in this post was the anomaly of the Simpson's Paradox

& please remember this Covid database of research articles/links was set up at Pandemic onset (Feb/March 2020)when there were no tests or vaccines & we were trying to get information to help us decide how we would continue our Clinic work with Patients and best advise them.

Set up for interested Patients, other Practitioners & Friends to help us make decisions.
