@Infoseepage I fully understand that, and I'd probably have done the same if I had to take care for my parents (also elderly, but independent). I felt a huge relief when they finally got vaccinated and visited them more often. And when I finally got vaccinated, I even visited them right after work instead of having a few days downtime.

Now the situation is a bit more relaxed, though we don't go out often except for walks or necessary shopping.
