Study suggests Merck’s Gardasil is effective in males

The Whitehouse Station, N.J., company said it remains on track to apply by year end for Food and Drug Administration approval to market Gardasil to boys and men ages 9 to 26 for prevention of external genital lesions caused by certain viral strains. "This is groundbreaking data," said Anna Giuliano, professor of medicine and epidemiology at University of South Florida, who co-authored the study. "To demonstrate that Gardasil prevents infection and disease at a very high level in males - that's the other half of the world." It was the first study to demonstrate Gardasil's effectiveness in males - prior studies had shown it could produce a positive immune response in males. The vaccine, which was launched in 2006, is currently approved in the U.S. for girls and women ages 9 through 26 to prevent cervical, vulvar and vaginal cancers, as well as genital warts and other lesions caused by certain viral strains. These diseases, in both males and females, share the same cause: Human papillomavirus, or HPV, which is transmitted through sexual contact. The cancers in men caused by HPV, however, are rarer than cervical cancer. [...]
