Since HPV can lead to cervical cancer, the results also could herald a drop in cancer rates for girls in this age range, too. The study illustrates a great advancement in public health, but it also underlines the consequences for those huge numbers of women and girls who are still not getting their vaccinations; in 2011, only 35 percent of girls ages 13-17 received all three shots in the vaccination series, and only 30 percent of women ages 19-26 had received the vaccine.

While the Centers for Disease control have deemed the shots safe, and especially effective for young girls, 16 percent of parents report not letting their children get the shots for fear of side effects. In fact, incidents of cancer from HPV are rising in the U.S., and the CDC says rates of inoculation are “unacceptably low.” These dangerous theories are fueled by conservatives like Rep.
