HPV (human papillomavirus) vaccination schedule: how many doses are recommended, and at what age should vaccination typically begin?

  1. 2 doses, starting at age 11–12 (for those who begin before age 15)
  2. 4 doses, given annually starting at age 11
  3. 1 dose only, starting at age 9
  4. 3 doses, starting at age 18
Show answer and explanation

Correct answer: A. 2 doses, starting at age 11–12 (for those who begin before age 15)

  • A. Correct. The CDC recommends HPV vaccination starting at age 11–12 (as early as age 9). Individuals who START the series before age 15 receive 2 doses (6–12 months apart). Those who start at age 15 or older (or who are immunocompromised) receive 3 doses.
  • B. 4 doses is not a correct HPV vaccination schedule.
  • C. A single dose is not part of the current approved HPV vaccination schedule.
  • D. 3 doses are only required for individuals who start at age 15 or older, or for immunocompromised patients. The standard schedule for 11-12 year olds is 2 doses.
