Yesterday I went up to hospital where I was invited to have my COVID-19 booster jab, it was just as before when I had my first two, conveyor belt of folk. Brilliant nurse this time, never felt anything at all, so did say thank you for that experience. 15 minutes sitting in recovery, just in case of adverse effects. Then a slow walk home in the drizzle kind of weather. A bit of a sore arm this morning, but that is it.
