Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a Phase 1,2 randomized, double-blind, multi-center, clinical trial, in participants aged 65 years and older, evaluating the immunogenicity and safety of a water-in-oil emulsion adjuvant (MAS-1 adjuvant, Mercia Pharma, Inc, Scarsdale, NY) combined with each of the three reduced HA antigen dose levels of trivalent influenza virus vaccine compared with licensed, unadjuvanted, standard dose trivalent virus (TIV). Immunogenicity for each of the three viral strains (A/H1N1, A/H3N2, and B virus) in the concurrent influenza seasonal vaccine will be assessed.
