Hi, R.
My sister is negative for COVID. She thinks it was a reaction to the flu shot. i think she got the single-strain shot. Interesting coincidence with your last post.
I would take the C-vaccine. If I had a bad reaction so be it. I could then be 95% sure I couldn't catch it or spread it. I'd still practice some distancing - no hugging someone who was moaning about being sick, and, as always, no hugging while I'm obviously contagious with anything. COVID or other.
Loving the rain. There wasn't a lot, but it was something.
