Isn't this a simpson's paradox thing?
>large proportion of the world's population is vaccinated
>given inordinate privileges over unvaccinated to travel, etc despite vaccines being ineffective at preventing transmission
>people who got the vaccine are more likely to be compliant and get tested, so they show up in the testing more
>as a result omicron is recorded to spread among them faster than the unvaccinated
so survivorship bias + simpsons paradox?
