I found this article that talks about the recent HPV vaccine for teens aged 12-17.  they are proud to say that 25% of all teens have received this vaccination, but they are hoping for eventually 90% of all teens to get the shot.  They still dont know if it is a full immunization or if there will need to be another booster in the later years.
