In Brief

A Phase 4 clinical trial evaluating MenACYW conjugate vaccine for Meningococcal Immunisation and Healthy Volunteers. Completed, enrolled 71 participants across 2 sites.

Detailed Summary

This study evaluated the immunogenicity and safety of a single dose of MenQuadfi® administered as a booster vaccine in toddlers 12 - 23 months of age in Argentina who had been primed with at least 1 dose of the quadrivalent meningococcal conjugate vaccines Nimenrix® or Menveo® during infancy to protect against invasive meningococcal disease (IMD). Participants received a single dose of MenQuadfi® at Visit 1. Participants provided 2 blood samples, one at D01 (Visit 1) pre-vaccination and another at D31 (Visit 2) post-vaccination for the immunogenicity assessments. Study included 2 visits at D01 (Visit 1) and at D31 (Visit 2), and 1 Telephone call (TC) for safety follow-up at D09 post-study vaccination.
