How many COVID shots did you get? I noticed my resting heart rate go up after the first one. So I never got another one.

When your immune system activity increases, generally so does your heart rate. It's fairly common to get sick and have an increased heart rate. A quick search for "heart rate when sick" will turn up a number of results explaining this, the mechanisms behind it, and more.

Sorry you missed out on simple, effective preventative health measures because of this misunderstanding.

COVID vaccines (and various other vaccines), often cause flu-like symptoms for a day or so; you should've been warned about this at the time. Pretty much anything that gives you a fever will boost your heart rate a bit.
