rOv-ASP-1 induce a low level of cross-reactive antibody response after immunization with TIV. Aged B6 mice were immunized i.m. with 0.6 μg of TIV alone or combined with rOv-ASP-1 (TIV + ASP). Plasma was collected at weeks 2 and 3 after each immunization and influenza-specific IgG was determined by ELISA using inactivated PR8 virus. Similar experiments were performed 3 times with similar results (3–4 mice/group).
