I saw
this Tweet yesterday showing CDC numbers for vaccine effectiveness in the US;
Unvaccinated: 451 cases per 100k
Vaccinated: 134 cases per 100k
Boosted: 48 cases per 100k
Unvaccinated: 6.1 deaths per 100k
Vaccinated: 0.5 deaths per 100k
Boosted: 0.1 deaths per 100k
Which looks pretty compelling. However, this is a Tweet so the author could say anything so I checked the CDC COVID website and wow, the vaccines work!
Here's the link but there also lots of other goodies on that site for data lovers.
Of course the COVID death rates look like they follow the '28 days from a COVID diagnosis' but you can click on 'Age Group' and see clear differences in vaccinated and unvaccinated elderly people. If the vaccine did not protect directly, there must be some some other protection from the vaccine other than stopping COVID.
