2 doses of HPV vaccine in girls may offer similar level of infection protection as 3 doses in young women


With the number of doses and cost of human papillomavirus (HPV) vaccines a barrier to global implementation, researchers have found that girls who received two doses of HPV vaccine had immune responses to HPV-16 and HPV-18 infection that were noninferior to (not worse than) the responses for young women who received three doses, according to a study in the May 1 issue of JAMA, a theme issue on child health. The authors note that more data on the duration of protection are needed before reduced-dose schedules can be recommended.
