Medical experts are expected to vote today on a proposal that boys should get the human papillomavirus (HPV) vaccine as a part of their routine immunizations.

The vaccine prevents cervical cancer as well as genital warts, anal and other cancers that are caused by HPV, which is commonly spread through sexual contact. The shot is already on the Center for Disease Control's vaccine schedule for girls and it has sparked some controversy.

Elizabeth Cohen breaks down the vaccine recommendations on American Morning today, explaining why the medical community is considering giving it to boys.
