Most of those we know who have had Covid multiple times have been “fully vaccinated and boosted” and they complain about it louder than people who have not been vaccinated. People I know who have not been vaccinated either did not realize they had it at all or have had it once.
My wife and I caught it from a close relative who spent a couple days with us and insisted that despite wheezing, sneezing, and having a runny nose and sore throat that it couldn't be Covid because she had been vaccinated and boosted. That is just my experience. For us it was just a typical cold/flu.
I wish I could get through to my neighbor - she is vaxxed and boosted, and still had a pretty severe case of Covid. She is much more fit than either my husband or I (teaches aerobics) but was much sicker with Covid than we were, and for much longer.
Yet, she tells us that she didn’t have a severe case because of the shots. She did end up with DVT in her leg though a few weeks after her last booster 😩
