A study of the sexually transmitted human papillomavirus has found that 3.4% of females in the U.S. ages 14 to 59 are infected with at least one of four viral types that could be blocked by the controversial vaccine Gardasil, researchers reported Tuesday. The study found that 3.1 million females have HPV types 6 or 11, which cause about 90% of genital warts cases, or types 16 or 18, which account for 70% of the roughly 11,000 cervical cancer cases diagnosed each year in the U.S.

The HPV vaccine may be controversial, but it works, new research shows. The rate of HPV infection among teenage girls dropped from 11.5% in the “pre-vaccine era” to 5.1% in the “vaccine era,” researchers from the Centers for Disease Control and Prevention reported Wednesday in the Journal of Infectious Diseases. That's a drop of 56%, the study notes. The infection rates cover the four types of HPV that are targeted by the vaccines Gardasil and Cervarix. Human papillomaviruses are the most common cause of sexually transmitted infections, and more than half of people who are sexually active become infected with one of the more than 40 types of HPV that are known to spread during vaginal, oral or anal sex, according to the National Cancer Institute . HPVs are responsible for nearly all cases of cervical cancer, along with most cases of anal cancer, the NCI says.

Wow. Can you believe it? Tetanus vaccinations do not make children likelier to walk barefoot on rusty nails. Masturbation does not cause blindness or hairy palms. And girls who get the HPV vaccination to protect against the sexually transmitted human papillomavirus, the cause of 70% of cervical cancer, do not turn slutty because of it. For this we actually had a study -- a sober, clinical response to the notional premise afoot in segments of American politics and culture that the vaccine, which can give young girls a lifetime's protection from cervical cancer, loosens their morals.

As GOP presidential candidates tussle over the latest issue to split the field — oddly enough, it's the rather obscure question of whether states should mandate vaccinating girls against a sexually transmitted virus — it's hard to tell which one ends up looking worst. But our vote goes to Minnesota Rep. Michele Bachmann, whose rumor-mongering rampage against a safe and effective vaccine could discourage parents from protecting their daughters against cancer. During Monday's debate, Bachmann and former Sen. Rick Santorum lashed out at Texas Gov. Rick Perry over his 2007 executive order that Texas schoolgirls had to be vaccinated against human papillomavirus (the order was later overturned by the state legislature)

Some girls may be more likely to overestimate the protection they receive from the HPV vaccine, new research shows. Human papillomaviris, the most common sexually transmitted infection, can infect the genital areas of men and women, cause genital warts and raise the risk of cervical cancer. The new study, published this week by the Archives of Pediatrics and Adolescent Medicine, looked at the perception of HPV risk among a population of 339 girls between age 13 and 21. At an average age of 16.8 years, 57.5% of these girls were sexually experienced, and most of them reported "continued need" to practice safe sex. However, a good 23.6% appeared to believe mistakenly that their risk of other sexually transmitted diseases was also lower -- even though the HPV vaccine does not protect against the rest of the pantheon of such diseases, such as HIV/AIDS, gonorrhea and syphilis.

Parents forgo vaccines for their teenage kids for a number of reasons, researchers said Monday in a paper reporting findings from the annual National Immunization Survey of Teens, which was published in the journal Pediatrics.  That might mean that public health agencies need to try new things to get immunizations on target to prevent spread of the human papilloma virus, the cause of cervical and other cancers. Overall, immunization rates among teenagers are on the way up, the Pediatrics study noted.

The HPV vaccine, which protects women against the human papilloma virus, is in the news once again, thanks to the recent GOP debate in which presidential candidate Michele Bachmann criticized Texas Gov. Rick Perry's proposed mandate of the vaccine and called it "...what potentially could be a very dangerous drug. " But that's not how most mainstream medical organizations in the U.S. see the HPV vaccine, approved in 2006 to prevent the spread of the virus, which can cause genital warts and may lead to cervical cancer.

Although HPV vaccinations can reduce the risk of cancer-causing infections in adolescent girls by half, immunization rates across the United States have stalled over the last year, according to the Centers for Disease Control and Prevention. At a Thursday press briefing, health officials said they were alarmed to find that despite the vaccine's proven effectiveness and safety, both parents and doctors were failing to ensure that teens received the three-dose human papillomavirus vaccine along with other recommended shots.

A shot that would make girls more inclined to have sex. When the HPV vaccine came on the scene, there were some who had that fear: This shot will reduce worries about a harmful sexually transmitted infection -- and reduce girls' inhibitions as well. And girls could mistakenly believe it's a magic bullet against pregnancy and other sexually transmitted diseases too. A new study kicks those fears to the curb. Researchers looked at girls who'd had an HPV vaccine and tracked the appointments they made and the advice they sought regarding sexual health over the next three years.

Katie Couric may want to brush up on her reporting skills before she takes on her new role as "global anchor" at Yahoo! , according to a number of critics displeased with a report about the HPV vaccine on her syndicated talk show, "Katie. " In a segment that aired Wednesday, Couric and a panel of guests discussed the supposed controversy surrounding the vaccine, known as Gardasil, which prevents transmission of a sexually transmitted disease that affects an estimated 79 million Americans and has been linked to numerous forms of cancer, particularly cervical.
