Could a single meningitis shot protect for years? a study investigates
NCT ID NCT07743411
First seen Aug 03, 2026 · Last updated Aug 04, 2026 · Updated 1 time
Summary
This study follows 180 children who received a meningitis vaccine (ACYW135 conjugate) years ago to see if their immune protection lasts. Researchers will measure antibody levels in blood samples taken 3 and 5 years after vaccination. The goal is to understand how long immunity persists and whether booster doses might be needed.
