NCT ID NCT07379151
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how well the MenFive (NmCV-5) meningitis vaccine still works more than five years after a single shot. Researchers will test the blood of 450 people in Mali and The Gambia who got the vaccine when they were 2 to 29 years old. The goal is to see if their immune system still has enough protection against five types of meningococcal bacteria.
