Though I've never had a flue vax, I did get both the Shingles and Covid ones a few years ago. Lets face it .... people are different, and both the viruses and vaccines can vary. Some get the Shingles and it's minor and some wish they were dead. Some get Covid and it's minor, and some ended up dead. I've known some of both fwiw for both the viruses and end result. No one I know had side effects from the vaxes.
Higgins had a thread about Shingles back when.... and that got me off my azz
