I never cared about catching the flu, had to take my college finals with it. Looking back that was probably stupid, but it didn't seem to be taken as seriously back then (Nineties), I was young, and I didn't have much choice. (EDIT, incidentally, that was the last time I'm aware I've had the flu. 1997.)
I got my first flu shot (and started taking zinc and vitamin C, unproven but harmless) a few months before major surgery in 2016 because if I'd gotten sick I would've needed to reschedule, and considering that we had to travel long distance, that was DEFINITELY not an option. Have been getting it yearly since then since my health has declined a bit (I'm prone to UTIs because of my surgery, and they feel JUST like the flu :roll ), I live with my elderly parents, and why not?
(Needles sometimes make me pass out--I experience vasovagal syncope due to numerous triggers, including injections, blood, overheating, stress, etc.--but this has fortunately never developed into a phobia, plus it doesn't always happen. I've found that not looking at the needle, and tensing my leg muscles, helps a lot. It's other people's reactions to me passing out--apparently my lips turn blue and I jerk and twitch a lot so they think I'm having a seizure and try to call an ambulance--that bother me. I had an EEG done at a doctor's request after one such incident, no signs of epilepsy though I didn't pass out during the test, but even me warning people about this doesn't always convince them that some types of fainting DO strongly resemble seizures yet aren't. Anyway... :blah )
No, I'm not against vaccination.
