I’m blaming the COVID vaccine 💉

I thought I was fine, but I’ve been dog tired all day today, and my arm where I got my latest COVID jab has been quite sore. I guess every jab has been this bad, and I know it’s worth it to avoid getting the COVID but it’s not been exactly a pleasant experience today. In contrast, I barely felt my flu shot in my other arm, and I doubt that’s making me feel so miserable at work today.
