2) People who are vaccinated are more likely to be in positions where they are exposed to COVID (remember who got vaccines first?).
3) People who are vaccinated are probably more likely to be around other people in general because they are at low risk of severe COVID reactions and are following guidelines (multiple state health officials: if you're fully vaccinated, it's ok to not wear a mask).
I don't see why this is a story.
At the very least, this data needs to be very carefully followed up on.
If 100% of people are vaccinated, 100% of covid infections will be among vaccinated people. In MA, ~70% of people are vaccinated. Vaccination rates are higher in some places. Given this, it's not surprising that most infections in certain places are among vaccinated people. The absolute number and how sick people are getting have to be considered as well.
If 100 unvaccinated people (that really didn't got the vaccine) get exposed in the same way than 100 vaccinated people, the numbers that will get infected would be the same?
People need to stop thinking about COVID as a disease like polio that we can relatively easily eradicate, and more like a bad flu that we simply coexist with even though annual vaccines are widely available.
