Serological responses against measles virus and RSV. (A): PA antibodies against measles virus in serum samples from cotton rats are shown in different groups collected before immunization and on Days 21, 35, 56, and 84. The second dose of recombinant virus was given on Day 56. (B) Serum IgG EIA antibodies against RSV are shown by absorbance at 450 nm. (C) NA titers against RSV are shown as 2n of the dilution of serum samples by a 50% plaque reduction. (D) IgG EIA antibodies in BAL obtained after the RSV challenge (Day 88) are shown by absorbance at 450 nm. BAL was diluted at 1:20. The bar represents the means of 3~4 rats per group ± SEM.
