The international symposium organized by the Center for Investigating Viral Immunity and Antagonism will focus on recent findings regarding the interaction of viral pathogens with the host immune system. Presentations will include investigations into the interaction of viruses with both host innate and adaptive immune responses. A special emphasis will be on immunity to emerging pathogens and human and primate immunology.  The symposium will begin at with a continental breakfast and include a morning and afternoon session of talks. A late afternoon poster session, held in conjunction with a cocktail hour, will showcase the work of Mount Sinai investigators as well as other scientists from the New York Metropolitan area.  The Day provides the Center an opportunity to share its work regarding Biodefense and Human Immunology with all those who are interested and create a forum for discussion.
