A Sourcing Study to Collect Human Blood Samples From Healthy Adults

Phase 4

Completed

• Conditions: Meningitis, Meningococcal
• Interventions: Biological: Meningococcal Groups A, C, W and Y Conjugate Vaccine (MenACWY); Biological: rMenB+OMV NZ vaccine

• Registration Number: NCT03493919
• Lead Sponsor: GlaxoSmithKline

Brief Summary

The purpose of this study was to collect large volumes of matched pairs of pre- and post-vaccination sera from healthy subjects who administered GlaxoSmithKline (GSK) Biologicals' vaccine against meningitis- MenACWY vaccine (Menveo) or rMenB+OMV NZ vaccine (Bexsero), which serves for the development, qualification, validation, and maintenance of immunological assays which supports the preclinical research activities and clinical development of GSK Biologicals' vaccines. The safety of the subjects given one of the two vaccines (Bexsero or Menveo), as per the recommended dosage and schedule were assessed during their participation in the study.
