HPV vaccines do not make girls more likely to engage in promiscuous sexual activity, according to a new study. Researchers tracked whether girls who had been given the vaccine against human papillomavirus became pregnant, sought birth control, or had tested positive for sexually transmitted diseases. The study found no difference on those markers of sexual activity between girls who did not receive the vaccine and those who did when they were 11 or 12 years old. One thousand four hundred girls in Georgia were involved in the study.
