Human papillomavirus, or HPV, is a highly infectious disease. Tens of millions of people carry this virus, and some strains can cause all sorts of horrid medical conditions, like genital warts in men and women, and several types of cancer, including cervical cancer in women. In the United States alone, 4,000 women die every year from cervical cancer, roughly one-third of the number who get it.
Two vaccines to prevent HPV infection were introduced a few years back, Gardasil and Cervarix. A new study, as reported by the New York Times and NBC News, shows the vaccine has been a huge success: HPV infection rates have dropped by a staggering 50 percent in U.S. teen girls since the introduction of the vaccine. This is despite the low uptake rate; only about a third of teens 13 to 17 have received the full course of three shots.
These results jibe well with an earlier report from Australia, too. There, HPV infection rates dropped 59 percent in girls and women ages 12 to 26, and 39 percent in boys and men.
This is great news! Now all we need to do is get more parents to give their girls and boys the vaccine. (Gardasil is recommended for both sexes, and Cervarix is just for girls). As the Times reports:
Dr. Frieden [of the Centers for Disease Control and Prevention] said the low vaccination rate in the United States means that 50,000 girls alive today will eventually develop fatal cervical cancer, deaths that could have been prevented if the country’s rate had been at 80 percent. For every year the rate lags, another 4,400 girls will develop cervical cancer in their lifetimes, he said*.
Not that this will be easy. The vaccine raised a hue and a cry from both the antivax left, and the sexually conservative right—HPV is a sexually transmitted disease. However, the NBC article reports that the CDC has found no evidence of major adverse effects, nor has there been an increase in sexual activity among girls who have had the shots. So really, no one should complain.
