ATLANTA - A vaccine against a cervical cancer virus has cut infections in teen girls by half, according to a study released Wednesday.
The study confirms research done before the HPV vaccine came on the market in 2006. But this is the first evidence of how well it works now that it is in general use.
"These are striking results, and I think they should be a wake-up call that we need to increase vaccination rates," said Thomas Frieden, director of the Centers for Disease Control and Prevention.
Only about half of teen girls in this country have gotten at least one dose, and just a third of teen girls have had all three shots, according to the CDC.
