CVIA 106 - Phase 2/3 study of the EuBiologics pentavalent meningococcal ACWYX conjugate vaccine compared to MENVEO® or Nimenrix ® in healthy children through adults

A Phase 2/3 observer-blind, randomized, active-controlled study of the EuBiologics pentavalent meningococcal ACWYX conjugate vaccine (EuNmCV-5 Multi-dose) in healthy infants, toddlers, children, adolescents, and adults, to examine its safety, immunogenicity (including lot-to-lot consistency), and immunological non-inferiority when compared to MENVEO® or Nimenrix® as well as its non-interference with routinely co-administered vaccines
