The first cervical cancer vaccine will be available to girls as young as nine.
The FDA has approved Gardasil, which should be in drug stores later this month. Scientists say the vaccine works best when given to girls before they begin having sex.
The Food and Drug Administration says the newly approved inoculations will have a "dramatic effect" on the health of women
And a deputy Health and Human Services secretary says Gardasil will put the worst types of human papillomavirus and most cervical cancers on "the list of diseases that no one need suffer or die from ever again."
HPV is a sexually transmitted disease that causes most cervical cancers and affects more than half of all sexually active adults at some time.
It has a list cost of 360 dollars, although Merck says it will give Gardasil free to the poor and uninsured.
