Vaccine Hyporesponse in Healthy Elderly Participants (MK-0000-131 AM2)

Status Completed

Clinical Trial Summary

This study evaluated whether it is possible in healthy elderly participants to generate baseline biomarker-based prediction rules (PdR) for vaccine response (post baseline absolute serum antibody titer) using each of the protocol selected vaccines separately; and examined the rank correlation coefficients of pairs of post vaccination antibody titers within the same elderly individuals.
