Aug. 27 (Bloomberg) -- Merck & Co.'s Gardasil vaccine, approved for preteen girls to prevent cervical cancer caused by a sexually transmitted virus, should also be given to teenage boys to help avert cancers linked to oral sex, researchers said.A growing body of research shows that human papilloma virus, responsible for cervical cancer, is also linked to about half of certain throat, or oropharyngeal, cancers. In a research review in the journal Cancer, doctors from the University of Texas M.D. Anderson Cancer Center said scientists should step up studies of the HPV vaccine in boys to expand the vaccine’s use.
