I've had the hpv vaccine, and haven't had sex. can i still get cervical cancer?

Almost no risk: First, cervical cancer is rare even in people at highest risk, i.e. infected with high risk types of HPV. Second, having never had vaginal sex, it is extremely unlikely you have been infected with HPV, hence no risk for cancer. Third, the current vaccine prevents infection with 7 HPV types that cause about 90% of cervical cancers. So even if exposed, you are highly protected. No worries at all!
