A recent study shows that giving girls the vaccine does not increase their likelihood of having sex:
Unlike previous studies that have largely relied on self-reported sexual activity, the new study measured clinical signs of sexual activity over several years, like whether the girls had been tested for a sexually transmitted infection, received contraceptive counseling or become pregnant.
“What we’ve done here is take a more objective approach and use clinical data to look at outcomes that are related to sexual activity and compare them,” Bednarczyk said.
This fuels my skepticism regarding the efficacy of scaring teens into celibacy.
