You’ve probably heard a lot about the HPV vaccine, which protects against the sexually transmitted pathogen human papillomavirus — which itself can lead to cancers of the cervix, anus, throat, and more. Unfortunately, there is a lot of misinformation about the vaccine, such as Michele Bachmann’s debunked claim that it causes mental retardation. But, even before Bachmann gave us her two cents, there have been plenty of falsehoods flying around about the HPV vaccine.
Myth: Vaccination against HPV will increase sexual promiscuity among vaccine recipients.
Fact: Studies show that this fear is unfounded.
A study published this month in the American Journal of Preventive Medicine contradicts this claim. In a group of more than 4,000 young females, there was no significant difference between the vaccinated and the unvaccinated in terms of number of sexual partners or the age at which sexual activity began.
There are around 150 strains of HPV, about 15 of which can cause cancer. Together, HPV-16 and HPV-18 cause about 70 percent of cervical cancers.
Besides, the vast majority of teenagers who choose abstinence do so for reasons other than a fear of contracting HPV. Additionally, HPV is one of many sexually transmitted infections (STIs); if fear of contracting an STI were the only factor in teenagers’ celibacy, a vaccine that protected against only one STI would not remove this fear.
(It might bear pointing out that when the HPV vaccine was approved for boys and men, fears about male promiscuity didn’t seem to run as rampant.)
Myth: Because the HPV vaccine only protects against two cancer-causing strains of HPV, it isn’t useful in cancer prevention.
Fact: The two cancer-causing strains of HPV that the vaccine protects against account for 70 percent of all cases of cervical cancer. Furthermore, Gardasil protects against two additional strains of HPV, which together are responsible for 90 percent of genital warts.
