How do people become infected with HPV?
By having sex, usually.
However, there are other ways to get infected. Researchers at the University of Texas discovered that virgin women can have HPV, that trace amounts of HPV can remain on medical equipment after disinfection, and that hand-to-genital contact can spread HPV. They summarized their findings in the best-titled journal article ever: "Penises Not Required: A Systematic Review of the Potential for Human Papillomavirus Horizontal Transmission that is Non-Sexual or does not Include Penile Penetration".
Abstinence education doesn't keep kids healthy
According to the Journal of Adolescent Health, abstinence-only sexual education doesn't reduce rates of pregnancies or STDs, despite how moral or logical it seems.
Do HPV vaccines make kids more likely to have sex?
No, kids will have sex regardless of whether they've been vaccinated. Lust isn't logical, remember?
The Canadian province of Ontario began offering free HPV vaccines to 8th grade girls at the start of the 2007-2008 school year. Researchers compared medical records of girls who were in the 8th grade during the first 2 years of the free HPV vaccination program against those of 8th grade girls from the previous 2 years. Data was obtained from the Ontario Health Insurance Plan (a universal healthcare system). Girls who were vaccinated against HPV under Ontario’s new initiative were just as likely as other girls to become pregnant or contract STDs other than those caused by HPV.
Of course, the vaccinated girls were much less likely to contract HPV.
