Clinical Trial Summary

In this study, the investigators will evaluate the immunogenicity of a quadrivalent conjugate meningococcal vaccine in healthy, plateletpheresis donors.

Description:

This will be an open-label prospective vaccine response study evaluating one dose of MenACWY-D in plateletpheresis donors at the Brigham and Women's Hospital (BWH). Potential participants will be divided into three groups according to the number of plateletpheresis within 365 days of enrollment (including the day of enrollment): 1-2 sessions group (considered as the control group), 3-19 sessions group, 20-24 sessions group and randomly sampled from in allocation proportions of 0.45, 0.10, and 0.45, respectively; justification for this approach is provided in the Statistical Analysis section. MenACWY-D vaccine will be administered to each patient. Pre- and post-vaccination blood will be collected to assess immunogenicity, likely using serum bactericidal antibody (SBA) against Neisseria meningitidis for each serogroup. Immunogenicity will be primarily evaluated by seroresponse such as a fourfold increase of SBA titers between pre- and post-vaccination.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Seroresponse of vaccine	The primary outcome will be the seroresponse of MenACYW-D vaccination, such as a fourfold change of SBA titers between pre- and post-vaccination for each of the 4 antigens.	Months 1 and 6.
Secondary	Seroprotection	The pre- and post-vaccination seroprotection, such as SBA titer greater than or equal to 1:8.	Months 1 and 6.
