Vaccines for Preteen and Teen Boys: What the CDC Recommends
Published November 14, 2026 · Written from AAP, KidsHealth and other pediatric sources
Many parents do not realize that a set of routine vaccines is due right when boys hit puberty. This is what the CDC schedule says. Schedules can be updated, so confirm the current version with your son's pediatrician.
The three routine vaccines at 11 to 12
- Tdap: one adolescent booster dose at age 11 to 12 (tetanus, diphtheria and pertussis).
- HPV: CDC recommends 2 doses at ages 11 to 12, given 6 to 12 months apart. It can be started as early as age 9, and 2 doses are enough if the first is given before the 15th birthday.
- MenACWY (meningococcal): CDC recommends all preteens get it at 11 to 12, with a booster shot at 16 because protection decreases over time.
Why HPV matters for boys
CDC says HPV vaccine protects your child from certain cancers later in life, and that all preteens need it.
Missed them?
CDC says catch-up HPV vaccination is recommended for everyone through age 18 if not fully vaccinated, and that teens and young adults through age 26 who did not start or finish the series also need it. Teens 13 to 18 who have not had Tdap should get one dose.
College note
CDC says many colleges require proof of MenACWY vaccination within 5 years before starting school, but recommends the booster for all teens who got their first shot before 16 regardless.
What to do
Bring this list to his next checkup and ask which shots he has had and which are due.
