The recommendations included the following:
- Boys ages 11 and 12 should be routinely vaccinated with the quadrivalent HPV vaccine (Gardasil).
- Males ages 13 to 21 should be vaccinated if they have not been fully immunized with the three-dose series.
- Males ages 22 to 26 may be vaccinated.
The HPV vaccination series can be started as young as age 9.
Aside from direct benefits, including protection against genital warts and anal cancer, vaccination of males is expected to lessen the burden of HPV in females, who are already advised to get routinely vaccinated at ages 11 and 12.
The recommendations regarding male vaccination replace the 2009 incarnation, which advised against routine use in boys but stated that the vaccine could be given to males ages 9 to 26 to reduce the risk of genital warts.
