According to news reports, the FDA will decide whether or not to extend the the administration of Gardasil, the HPV vaccine, to women ages 27-45, by this summer. Currently, Gardasil is only approved for use in women ages 9-26. A spokeswoman for Merck, the company that produces Gardasil, emphasized that the vaccine prevents four different strains of HPV, so even women who already have HPV can consider getting the Gardasil shots in order to prevent strains they do not have. The current HPV tests do not differentiate between the types of the virus. [Gardasil]
