Some useful Covid data

Stuff’s Keith Lynch has some really useful data showing hospitalisation rates for both Delta and Omicron Covid, and the impact of vaccination and also a booster. There’s data for different age groups.

Take me. I’m aged 54. If I got Delta and was unvaccinated there was a 1 in 12 chance it would be so serious I would need to go to hospital.

For Omicron, if unvaccinated the chance of needing hospitalisation is 1 in 36. That’s still pretty high.

I’m currently fully vaccinated. That has reduced my hospitalisation chance to 1 in 100. That’s a lot better.

Later today I get my booster. This reduces my chance of hospitalisation to 1 in 350.

If you’re over 75, the chances of hospitalisation is:

  • Delta unvaccinated 1 in 2
  • Omicron unvaccinated 1 in 5
  • Omicron vaccinated 1 in 14
  • Omicron booster 1 in 50

And for a 25 year old:

  • Delta unvaccinated 1 in 80
  • Omicron unvaccinated 1 in 240
  • Omicron vaccinated 1 in 1,000
  • Omicron booster 1 in 3,300
