HPV Vaccine, Yes/No?

I took the first shot of Gardasil 4 about 9 years ago and then I read about the side effects and was too scared to take the rest of the shots.

My mom said that she thinks that she had some minor cell changes once after giving birth to me, but they disappeared by themselves. Otherwise, she never had any cell changes.

My younger sister took all shots and, as far as I know, she had no side effects.

I'm currently being offered Gardasil 9 for free, with only 2 shots total.

I've been googling and I can't seem to come to a conclusion. Some people say that they've taken it with no side effects, some people say they took it and still got HPV. I saw an interview with a girl who got paralyzed form the vaccine.

I think 9 years ago there was a bigger "wave" of people who mistrusted the vaccine. Today, they claim that they've seen that the vaccine is effective. And by now the vaccine has been around for way longer...

I don't know what to do!! My grandma had cancer in the uterus, not the cervix. I don't know the cause, perhaps old age (since cancer in the uterus is more common in older ages) or the fact that she had breast cancer 20 years earlier.

Anyway, I'm a virgin and when I start having sex I don't plan to sleep around because that's not my thing (there's a reason I'm a virgin). However, I know that's no guarantee because the man can have HPV and pass it on. You never know if they'll cheat either.. And obviously you never know if someone sexually assaults you.

Shouldn't pap smears be enough? They've been around for a looong time after all without having to inject something in you.

I know this is a choice I need to make myself but I honestly need some more insights, please.
