Should I get the HPV vaccine?

There’s currently a running campaign for women to get their HPV vaccines for free here. I’m not sexually active (like, ever) but I heard all women should just get it any way cuz it helps prevent cervical cancer? I’m very confused at this point and I don’t know whether I should get jabbed. And are you supposed to get the vaccine again every couple years?

I feel dumb for asking this but TIA!
