1/It's time to review recent data around #COVID19 outcomes by vaccination status.
Let's start with the risk of testing positive for #COVID19. Nationwide, an unvaccinated person has a 5X higher risk of testing positive for COVID.

2/Here are those data broken out by age group. Every fully vaccinated age group has a lower risk than every unvaccinated group.
3/The impact of vaccination on risk of death from #COVID19 is even more stark.
In October, an unvaccinated person had a 14X higher risk of dying from COVID19 compared to a fully vaccinated person.

4/In terms of risk of death by age, a fully vaccinated 80+ y/o has roughly the same risk of death from #COVID19 as an unvaccinated 50-64 year old.
Same with a fully vaccinated 65-79 y/o and an unvaccinated 30-49 y/o.

5/What role do boosters play?
In Oct, an unvaccinated person had a 10X higher risk of testing positive for COVID compared to a boosted person.
In Oct, an unvaccinated person had a 10X higher risk of testing positive for COVID compared to a boosted person.
6/The impact of boosters on death rates is even more striking.
In Oct, an unvaccinated person had a 20X lower risk of dying from #COVID19 compared to a fully vaccinated person with an additional/booster dose.
Not many medical interventions can achieve that.

7/Let's look at hospitalization by vaccine status.
For adults, the cumulative #COVID19 associated hospitalization rate was about 8X higher in unvaccinated persons (blue line) compared with vaccinated ones (green line).

8/What does all this mean? First, it is continued evidence for the performance of vaccines. Are they 100% effective? No, nothing in medicine is.
Second, are they doing what they were designed to do? Yes, they are keeping people out of the hospital and alive.

9/Third, do boosters matter? Yes, absolutely, especially in light of #Omicron.
Get vaccinated and, if you have, get boosted when eligible.

10/Erratum--tweet #6 of this thread should read:
"In Oct, an unvaccinated person had a 20X *higher* risk of dying from #COVID19 compared to a fully vaccinated person with an additional/booster dose."
"In Oct, an unvaccinated person had a 20X *higher* risk of dying from #COVID19 compared to a fully vaccinated person with an additional/booster dose."
