Why Vaccinate?

  • Cancer Prevention: HPV vaccination can prevent over 90% of cancers caused by HPV, including cervical, anal, vaginal, vulvar, and oropharyngeal cancers.
  • Best Timing: The vaccine works best when given at age 11-12, before exposure to the virus. Vaccination can start as early as age 9.
  • Catch-Up Vaccination: Individuals aged 13-26 who have not been adequately vaccinated should complete the series.

Vaccination Schedule

  • Ages 9-14: Two doses of the HPV vaccine are recommended, with the second dose administered 6 to 12 months after the first.
  • Ages 15-26: Three doses are recommended, administered at 0, 1-2, and 6 months.
  • Ages 27-45: Vaccination may be considered based on individual risk factors and a discussion with a healthcare provider. The vaccine is less effective in this age group due to the potential prior exposure to HPV.
