Official Title: A Phase 2/3, Open Label, Randomised Study of the Safety, Reactogenicity and Immunogenicity of a Single Dose of Novartis Meningococcal ACWY (Menveo) or GSK Meningococcal ACWY Conjugate Vaccine in Adole
Brief Summary: There is evidence of waning immunity in individuals vaccinated against meningitis C as part of the UK infant immunisation schedule. The intention of this study is to contact participants of a previous NVEC (National Vaccine Evalutaion Consortium) clinical trial (a PreSchool Men C trial, in which participants were randomised to receive Meningitec, Menjugate or Neisvac-C). They will be invited to enrol and will be randomised to receive one of two quadrivalent meningococcal ACWY vaccines, to look at the boosting effect they may confer.
