DEAR MAYO CLINIC: I've heard that the HPV vaccine is now being recommended for boys. Why? Does my 12-year-old son really need this? ANSWER: Yes, the quadrivalent HPV4 (brand name Gardasil) vaccine is now routinely recommended for all boys 11 to 12 years of age. It is a good idea for boys to receive the vaccine against human papillomavirus (HPV) infection.
