There is also rate data from UK on covid delta (week 32-35 2021), breakdown by vax status & age, see Figure 2a. Cases under 40 is 1/2 vax/unvax, cases over 40 is actually slightly larger for vax than unvax. I had a sense vaccines are not perfect wrt infection, but didn't expect actual numbers to be that close.

Fortunately vaccines are very still very good at preventing severe cases (hospitaliations), see Figure 2d.

Preventing severe cases really only benefit the vaccinated and perhaps medical providers. It’s a lousy justification for a mandate that forces someone to do something that cannot be undone.

Great document, thanks for the link.

The document says that >97% of the blood-donor population in the UK has some kind of antibodies, either from natural infection or vaccines. This seems like an astonishingly high number.
