Summary

This study will measure immune persistence of the NmCV-5 more than 5 years after a single dose vaccination in participants 2-29 years of age in Mali and The Gambia.

Detailed description

This non-interventional long-term follow-up study will involve one telephonic contact in all 1800 former participants from study ACYWX-03 followed by one visit beyond five years after vaccination in a subset of 450 participants. This subset will be randomly selected to participate in a follow-on immune persistence evaluation. To document the duration of the immune response and any requirement of booster dose in the target population, this study is intended to explore antibody persistence.
