Brief summary

The aim of the study is to assess the safety of Menactra vaccine in infants, toddlers, children, adolescents, and adults Objective: * To describe the safety profile after each and any dose (when applicable) of Menactra vaccine in participants aged 9 months to 55 years for registration.

Detailed description

Infants and toddlers will receive 2 doses of vaccine 3 months apart. Children ≥ 2 years through adults aged 55 years will receive 1 dose of vaccine. All participants will be evaluated for safety up to 28 days post-vaccination.
