My wife’s family (including her) are all sick with covid. That’s 5 people. They all skipped this year’s booster (due to negligence), and I was the only one to take it.
My wife was the first to test positive on the 26th, I of course spent the most time with her, went to all the same gatherings, hugs, etc. I have spent hours (masked up) in urgent care and ER, in enclosed spaces like cars and homes, taking care of her and her parents. I have tested negative daily.
The boosters work. Please, for you and your loved ones that would be burdened should you need serious care, keep up with the boosters.
