I’m struggling with the same angst since I had covid last November.. I also have ongoing symptoms and had some tests done to rule out other causes but nothing showed up. It’s truly frustrating to seek medical attention and no one is connecting the dots but that’s another discussion which sadly comes up all too often. I have decided to take the vaccine because I don’t think covid is over at least not for seniors or people with illnesses, I have heard that healthy people don’t need a booster for now, the numbers are always lower in the summer but there’s another variant making the scene in Europe and it’s a matter of time that it will be here..no info on the new variant so we shall no doubt find out sooner enough.
