I do hope you recovered quickly. I know some people that received the vaccine still managed to get COVID. However, my understanding is that these cases were generally milder and of shorter duration.
I am taking Hydroxyurea for ET and apparently at high risk for COVID and nasty complications (also in my 80’s).My husband is in his 80’s type 2 diabetic and also at high risk. Despite the having all the vaccine recommended, we still were careful about masking, where we went etc. We got through with no problems, managed lunches out at parks, camped with our camper and kept ourselves busy. Missed some family visits but we were fine in most ways.
