An adolescent received his first meningococcal conjugate quadrivalent (MenACWY) vaccine at age 13 years, when should he receive his booster dose?

The timing of booster doses for the meningococcal conjugate quadrivalent (MenACWY) vaccine is based on recommendations from public health authorities aimed at ensuring continued immunity against bacterial meningitis caused by serogroups A, C, W, and Y.

According to the vaccination schedule, adolescents who receive their first dose of the MenACWY vaccine at age 13 should receive a booster dose at age 16 years. This schedule is designed to provide enhanced protection during the critical years when adolescents are at higher risk for meningococcal disease, particularly in college or communal living situations. The initial dose at age 13 provides baseline immunity, but a booster at 16 years is necessary to maintain adequate protection, as immunity can wane over time.

This approach supports public health efforts to reduce the incidence of meningococcal disease and is also aligned with best practices in vaccine administration for adolescents.
