The Centers for Disease Control has voted to make the new HPV vaccine, which now protects against 9 strains of the disease, part of the standard vaccination schedule for children.
Dr. Kevin Ault, an obstetrician, discusses what has happened, what it means, the difference between the old and new vaccines, when to get it, what to say to people who don't believe in vaccines and the fear of some that the vaccine is giving children permission to have sex.
