🇩🇰Updated data from Denmark showing highest rates of infection in those who have received *boosters* who are >40 yo
🟢booster
🔵2 doses
🔴previously infected
🟠unvaccinated
But see adjustment for test # s below
Denmark now w/around 85% omicron

The appearance of negative vax efficacy against infection has been puzzling, especially when separating out prev infected, but @KT_Baek seems to be onto something⬇️ when he adjusts for # of tests taken; this gives v similar infection rates in all 4 groups

Though 2 & 3 doses of vax not effectively preventing infection, 2 doses evidently protecting against severe disease & death in adults & 3 doses seem to offer extra protection in those >70
👇 hospitalization & death rates/100,000 by vax status

🟠unvaccinated

Adjusting for test rate may explain the negative vax efficacy seen in Ontario (

), but Denmark is giving us a clear picture of a future where neither 2 nor 3 doses prevents infection.
Can the @CDCgov please make use of @SSI_dk & @KT_Baek 's data & analyses?

indlæggelser= hospitalizations
døde= deaths
Unfortunately there is no data yet being released from @SSI_dk on previous infection's protectiveness against severe disease
