Just one dose of the HPV vaccine Cervarix appears to provide enough of an immune response to protect women from two strains of human papillomavirus (HPV) and ultimately cervical cancer, according to a new study published Monday.
HPV is the most common sexually transmitted infection (STI), according to the U.S. Centers for Disease Control and Prevention (CDC). The infection, transmitted through genital contact, is the primary cause of cervical cancer, which affects about 10,300 women in the United States each year. It causes about 275,000 deaths annually worldwide and is a leading cause of cancer deaths among women in low-income countries, according to the World Health Organization.
“Cervical cancer is a major cause of public health concern, especially in less developed countries where about 85% of cervical cancer occurs,” says study author Mahboobeh Safaeian. “The reason for that is mainly because of lack of screening infrastructure offered.” FULL POST

Cases of human papillomavirus (HPV) have significantly decreased since the advent of the HPV vaccine in 2006, according to the Centers for Disease Control and Prevention, and numbers have outpaced even their greatest predictions.
"The prevalence of the types of HPV that commonly cause cervical cancer in women has dropped by about half in girls ages 14 to 19," said Dr. Thomas Frieden, CDC director. "That decline is even better than we had hoped for." FULL POST

Scientists may be able to predict throat cancers caused by the human papillomavirus (HPV) more than 10 years before patients get diagnosed, according to research published in the Journal of Clinical Oncology.
Using a blood test that is still in the research stage, experts were able to detect blood markers indicating early signs of the disease.
Actor Michael Douglas recently made headlines when The Guardian reported he said his throat cancer may have been caused in part by HPV transmitted through oral sex. Douglas later said he simply was stating that oral sex can lead to cancer.
HPV: What you need to know
HPV is the most common type of sexually transmitted virus in the United States and is passed on through sexual contact – genital or oral. There are more than 40 types of HPV, according to the Centers for Disease Control and Prevention, and nearly all sexually active men and women will get at least one type of HPV during their lifetime.

A new survey finds even though vaccines for certain teenage illnesses are available and are found to be safe, many parents aren't having their teens inoculated. The question is why?
Researchers looked at parent questionnaires collected through a national survey called "Reasons for Not Vaccinating Adolescents: National Survey of Teens, 2008-2010." Investigators wanted to better understand why moms and dads aren't taking their older children in for recommended inoculations.
“These vaccines are safe and effective and people should really have their teens get them," says Dr. Paul Darden, lead author of the study and professor of pediatrics at the University of Oklahoma College of Medicine. “Parents say pediatricians are telling them about the vaccines, yet they just don’t seem to understand why they are necessary or are skeptical about their safety."

There are about 20 million new sexually transmitted infections (STIs) each year in the United States, costing some $16 billion in direct medical costs, according to numbers released Wednesday by the Centers for Disease Control and Prevention.
Young people are disproportionately affected, the agency said, with half of all new infections occurring in people ages 15 through 24.
"In general, CDC estimated the total number of infections in the calendar year, rather than the number of individuals with infection, since one person can have more than one STI at a given time" or more than one episode of a single STI, officials said. But "CDC used conservative assumptions in generating its estimates, so the true numbers of STIs in the United States may be even higher than estimated." FULL POST

There's been a lot of controversy over the HPV vaccine. Because Gardasil is designed to protect young people against human papillomavirus, a common sexually transmitted disease, some people believe the inoculation gives teens the go-ahead to have sex.
Researchers are finding that's not the case.
HPV is known to be the cause of a number of illnesses, including mouth and throat cancer, genital warts and cervical cancer. Since 2006, the Centers for Disease Control and Prevention has recommended that all girls aged 11 and 12 receive the HPV vaccine to protect themselves. The American Academy of Pediatrics has also advised that girls and boys at that age be given the shot to fight the virus strain.
But according to a new Kaiser Permanete/Emory University study published in this week's edition of the journal Pediatrics, the vaccine has yet to be embraced by the general public. By 2010, fewer than half of girls eligible for the vaccine had received even one dose.
Investigators believe that may be in part because some people who oppose the vaccine wrongly believe that it also protects against pregnancy and other sexually transmitted diseases, which would open the door for pre-teens to engage in sexual activity at an early age.

The most common sexually transmitted disease is often silent and invisible: human papillomavirus (also called HPV). But in some people HPV leads to genital warts and cancers – notably, cervical cancer.
The vaccines Gardasil and Cervarix were designed as a prevention for young women who have not yet been exposed to HPV. Men up to age 26 are also eligible for Gardasil to protect against HPV. But there are a lot of people out there who still have HPV, and nothing protects against all 130 strains of the virus. At least half of all sexually active males and females have had HPV, according to the Centers for Disease Control and Prevention.
A Pennsylvania start-up company called Inovio Pharmaceuticals has developed an experimental vaccine for people who already have HPV and precancerous lesions that are associated with it. A new study demonstrating the vaccine's safety and potential effectiveness was published this week in the journal Science Translational Medicine.

A vaccine against human papillomavirus, commonly known as HPV, a virus known to cause genital warts and cervical cancer, is safe, according to a study of almost 200,000 girls who received the vaccine.
Concerns over the safety of the Gardasil vaccine emerged shortly after the Food and Drug Administration approved it in 2006, despite the Centers for Disease Control and Prevention, the American Academy of Pediatrics and the American Academy of Family Physicians all deeming the vaccine safe and recommending it be given to girls ages 11 and 12.
Dr. Nicola Klein, pediatrician and lead author of the study published Monday in the Archives of Pediatrics & Adolescent Medicine, says she hopes the study puts those rumors to rest. FULL POST

As the number of American parents increasingly leave their baby boys uncircumcised, HIV and other sexually transmitted disease rates are likely to climb, according to researchers from Johns Hopkins University, and the costs associated with those diseases could reach into the billions.
"The medical benefits of male circumcision are quite clear," said Dr. Aaron Tobian, an assistant professor of pathology at Johns Hopkins and lead author of the study published Monday in the Archives of Pediatric and Adolescent Medicine. "But while the medical evidence has been increasingly more positive, male circumcision rates in the U.S. have been decreasing."
Specifically, he says, circumcision rates had been fairly stable in the 1970s, at about 79%. By 1999, he says less than 63% of boys had the procedure, and by 2010, the rate had dropped to 55%.

A new study released in this week’s British Medical Journal finds that the human papillomavirus, or HPV, vaccine, Gardasil, given to young women to help prevent cervical cancer may have some additional benefits for women who are already infected with HPV.
Gardasil maker Merck funded the study and found that the vaccine reduced re-occurrence of HPV related diseases by 46% among women who were infected prior to vaccination.
