Females between nine and 26 should be routinely vaccinated against human papillomavirus, a sexually transmitted disease that can cause genital warts and cervical cancer, says Canada's expert advisory panel on immunization.
In recommendations released Tuesday, the National Advisory Committee on Immunization (NACI) said Canadian girls aged nine to 13 who have not yet become sexually active should be immunized with Gardasil, a vaccine that protects against four strains of human papillomavirus, or HPV.
The Canadian committee's recommendations differ somewhat from those of its American counterpart. The U.S. Advisory Committee on Immunization Practices issued guidelines in June suggesting that all 11-and 12-year-old females be routinely vaccinated against HPV, while girls as young as nine could get immunized at the discretion of their doctors.
