Day 530 of self-isolation - Which vaccine?

Which vaccine?

Which vaccine is the best? I'm not bothered about catching the virus if all it leads to is a couple of days in bed or less. But I don't want to have to go to hospital, I don't want to need ICU and I don't want to die. So which vaccine is best?

It turns out, the Oxford University/AstroZeneca vaccine performs the best (Covishield is a brand name of the AZ vaccine).

This table looks at the outcomes of people who test positive for the virus. If you're unvaccinated, you have a 13% chance of having to go to hospital, and 1.3% chance of death. But if you have the AZ vaccine, that's a 1.5% chance of hospital, and 0.03% chance of death.

I got the Pfizer, which gives me a 2% chance of hospital, and 0.15% chance of death, so it is nearly as good as AZ.

Sinopharm (the Chinese vaccine) is the worst vaccine in this study, but still a lot better than not getting vaccinated
