Two years after HPV-vaccine Gardasil was introduced to the public in 2006, CNN examined reports of serious adverse side effects linked to the drug. Gardasil is marketed primarily to young women, as a preventive treatment against cervical cancer. It protects against four types of human papillomavirus, which is linked to causing cervical cancer. However, some medical experts argue the vaccine is unnecessary, as the body naturally clears more than 90 percent of HPV, and cervical cancer can be detected with an annual pap smear.
In 2010, the Garasil vaccine was approved for use in boys and young men, to prevent the spread of HPV, which is a sexually transmitted virus. In this instance, the drug’s manufacturer, Merck, promotes the vaccine as an additional safeguard against oral, penile and anal cancers.
