Conduct expert scientific evaluation of influenza vaccines from BARDA partners, assessing immunogen design, adjuvant strategies, mechanisms of protection, scientific rationale for novel approaches, likelihood of achieving broadly protective immunity, adequacy of proposed immunological assays and correlates of protection, and translational potential from preclinical models to human efficacy. Major Duties & Responsibilities: Provide scientific expertise in influenza vaccine development and evaluation, with deep understanding of zoonotic influenza, influenza-specific immunity including antigenic drift/shift, cross-reactive antibody responses, heterosubtypic immunity, neuraminidase and non-HA antibodies, mucosal immunity, and T cell responses to conserved epitopes.
