Perhaps that's part of it, but more specifically the vaccine has not been tested on women over the age of 26. As a result, the FDA will not license (http://www.cdc.gov/STD/HPV/STDFact-HPV-vaccine.htm#hpvvac22) the vaccine for older women. From that site:
The vaccine has been extensively tested in 9-to-26 year-old girls/women, but research on the vaccine’s efficacy has only recently begun with males, and with women older than 26 years of age. The FDA will consider licensing the vaccine for these other groups when the research is completed to show that it is safe and effective in those groups.
