The anti-vaccination movement has long been a public menace. It's responsible for the resurgence of numerous serious diseases that were on the decline, including measles, mumps and whooping cough. Now the movement has been given a big booster shot by Katie Couric, who devoted a large portion of her daily talk show Wednesday to some highly emotional and scientifically dubious claims by critics of Gardasil, a leading vaccine for human papillomavirus, or HPV. The segment focused on a mother convinced that her 20-year-old daughter died after a cycle of Gardasil immunization, and a second family whose 14-year-old daughter fell ill after the shots.

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.

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.

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.

Researchers at the U.S. Centers for Disease Control said Tuesday that vaccination coverage levels in U.S. adults were “unacceptably low,” and that public health workers need to do more to make sure adults got immunizations to protect them from diseases including whooping cough, shingles and pneumonia. The team, writing in the CDC's Morbidity and Mortality Weekly Report , updated statistics on vaccine coverage for those diseases as well as cervical cancer, hepatitis A and B and other preventable illnesses. There were “modest gains” in coverage for the Tdap (tetanus, diphtheria and pertussis)

This year's Annual Report to the Nation on the Status of Cancer, released online Monday, brought Americans good news and bad. Extending a trend since the early 1990s, authors reported in the Journal of the National Cancer Institute that cancer deaths have continued to fall in the United States, with rates declining 1.5% per year for all cancers, in both sexes combined, from 2000 to 2009. Deaths from the most common cancers - including lung,...
