  • Meningococcal ACWY
  • Vaccine Recommendations

If a healthy child received MenACWY or meningococcal polysaccharide (MPSV4) vaccination prior to international travel at age 9 years, will two additional doses of MenACWY be needed?

Yes. Doses of any quadrivalent meningococcal 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 either MPSV4 or MenACWY before age 10 years, they should receive a dose of MenACWY at 11 or 12 years and a booster dose at age 16.
