If a healthy child received meningococcal ACWY vaccination prior to international travel at age 9 years, will two additional doses of MenACWY be needed?

Yes. Doses of any meningococcal ACWY vaccine given before 10 years of age should not be counted as part of the adolescent MenACWY series. If a child received a dose of MenACWY before age 10 years, they should receive a dose of MenACWY at 11 or 12 years and a booster dose at age 16.
