Open-Label, Randomized Phase 1b Study of the Safety & Immunogenicity of Investigational Seasonal Influenza DNA Vaccine Followed by TIV Administered Intradermally (ID) or Intramuscularly (IM) in Healthy Adults 18-70 Years

This is a Phase Ib study in healthy adults (18-70 years) to evaluate the safety, tolerability, and immunogenicity of same season and sequential season vaccination schedules consisting of the 2012/2013 seasonal influenza DNA vaccine (HA DNA) and licensed trivalent influenza vaccine (TIV) administered intradermally (ID) or intramuscularly (IM). The hypothesis is that evaluation of these investigational schedules will inform development of novel influenza vaccine strategies that may offer improved and cross-protective immunity against antigenically diverse influenza strains.

Stanford is now accepting new patients for this trial. Please contact Sally Mackey at 6507367388 for more information.
