I know quite a few people in this situation too. I don’t believe it is a coincidences, I believe the vaccine is playing a role in reducing transmission. And no I am not on Pfizer’s payroll.Again from my own personal experience and not from any statistics or crap posted on the Internet but I currently have Covid in my house and 2 other family member households currently have Covid in the house.
The only ones to currently not have caught it are the ones who have been double vaccinated.
Coincidence? Maybe but I don't believe so.
