2nd vaccine shot

I got my 2nd Moderna COVID-19 vaccine shot yesterday afternoon. I felt fine afterwards. During the rest of the day and night, my arm became slightly sore, but not nearly as much as after the first shot.

I went to bed around 2:40am, still feeling mostly fine. I felt very tired and worn out, as I'd done a lot of work, including physical activity, that afternoon and evening

A few hours later (about 14 hours after the shot), I woke up with a mild fever and chills/shivering. I put more blankets on the bed and managed to sleep some more off and on. The mild fever (ranging from 100.2 to 100.9) and headache persisted till the early afternoon. Then I took some acetaminophen; the fever went down and I started feeling better. My joints & some muscles were also achy today but they are feeling better now too.

The fever hasn't come back, so unless it returns during the night, I think I'm over it.
