Antibody responses in BAL fluid of mice immunized with FI-RSV or convalescent from RSV infection. BALB/c mice were immunized with FI-RSV on days 0 and 21, with RSV on day 0, or not treated (naïve), then challenged with RSV on day 35. BAL fluid was collected on day 28 (pre-challenge) and 4- or 8-days post-challenge and IgG antibody responses were measured by ELISA against G169–198 peptide (G) or whole RSV. Mean ± SEM of 3 mice per group at 1:5 BAL fluid dilutions. * p < 0.05 compared to naïve BAL fluid tested against RSV at each time point; ** p < 0.05 compared to naïve BAL fluid tested against G169–198 peptide at each time point by t-test.
