Girls ages 15-19 who receive the human papillomavirus (HPV)
vaccine are no more likely to be sexually active or to have
more partners than their unvaccinated peers, a new study
Furthermore, among sexually active girls, those who were
vaccinated against the STD were more likely to report
consistent condom use than those who had not had the shot.
"This is all preliminary data, but it shows no association
between HPV vaccination and sexual risk," said lead author
Nicole C. Liddon of CDC.
Liddon and colleagues studied a nationally representative
sample of females ages 15-24. By the end of 2008, the
investigators found 30 percent of girls ages 15-19 and 16
percent of women age 20-24 had received at least one dose in
the three-shot series. About 25 percent of girls ages 14-19
and nearly 45 percent of women 20-24 have been infected with
No difference in vaccine rates were seen by race or ethnicity
among girls ages 15-19, but 20- to 24-year-old non-Hispanic
black women were less likely than their white peers to have
The study, "Human Papillomavirus Vaccine and Sexual Behavior
Among Adolescents and Young Women," was published in the
American Journal of Preventive Medicine (2012;42(1):44-52).
