When is the Men-ACWY vaccine typically given?

The Men-ACWY vaccine, which protects against meningococcal disease caused by serogroups A, C, W, and Y, is typically administered as a part of routine adolescent immunizations. The recommended age for this vaccine is between 11 to 12 years, with a booster dose advised at age 16. This aligns closely with the answer indicating 13-15 years, which captures the interval for the booster.

Vaccination during these ages is critical because adolescents are at higher risk for meningococcal disease, and the immune response offered by the vaccine is strongest during these years. Additionally, providing the vaccine at these ages helps maintain immunity during the high-risk years of late adolescence and early adulthood, such as during college years or in crowded living conditions.

The other age options do not align with the standard practice guidelines. The age range of 6-24 months relates more to other vaccines and is not the recommended period for the Men-ACWY. Moreover, the ages of 3 years and 4 months fall outside of the adolescent-focused recommendations in the current vaccination schedule.
