Sorry to hear about the family losses. Both of my parents went a while ago now. It can be no fun in several respects. I had to find residential care for my mom after dad died.
I wonder if 4th jabs will be rolled down the age groups again. Down to some point anyway. Suppose it may depend on how long the previous jabs are found to be effective.
I bumped into an uncle of mine last week. 92, he was shopping. I must admit I feel that masks for all would help in that area especially for the older age ranges - well below my uncle's.
