Dose-finding and Safety of 2 Intradermal MEN-ACYW135-conjugate Vaccines

Phase 1
Completed
Conditions
Meningococcal Disease
Interventions
Biological: MEN-ACYW135 reduced-dose intradermal administration
Registration Number
NCT01782066
Lead Sponsor
Leiden University Medical Center
Brief Summary

Invasive meningococcal disease is a worldwide problem with serious repercussions for those affected. Vaccination is recognized as the best way to combat it. The cost of vaccination is prohibitive in many low-resource settings at home and abroad. By harnessing the special immunologic properties of the skin, a dose reduction may be achieved by intradermal administration of the vaccine. The cost savings associated with dose reduction will increase availability of the vaccine.
