I am seeing the same thing. My daughter's family is un-vaxxed. Five children, home-schooled, live on a farm and dad is a farmer. In the past year, every time they go somewhere where there's a crowd--family reunion, wedding, etc, they get something cold/flu-like and pass it all around the family. It's been four times in 12 months now. And this is a healthy family in general. No vaccines ever for the kids. The illnesses they are catching are pretty mild, but the increased frequency is very noticeable. I'm unvaxxed as well and I have gotten several colds in spite of my 10,000 IU Vitamin D daily. Maybe I've had Covid, but I don't test.
