Pulmonary cell infiltration following FI-RSV and FI-Vero vaccination.

<p>(A) Total BAL cell counts in the lungs of mice i.m. vaccinated with FI-RSV A2 and live RSV A2 challenged (FI-A2+A2), mice vaccinated with FI-Vero cell lysate supernatant and then challenged with Vero cell lysate supernatant (FI-Vero+Vero), or mice vaccinated with FI-Vero lysate and G-A2 peptide and challenged with either RSV A2 (FI-Vero+G-A2+A2) or uninfected, Vero lysate (FI-Vero+G-A2+Vero) (day 5 post-infection). (B) Total neutrophils (PMN), lymphocytes, (LYM), macrophages (MAC) and eosinophils (EOS) counts in BAL. (C) Total BAL cell counts in the lungs of mice vaccinated with or without FI-Vero supernatant at day 5 post-RSV A2 challenge. (D) Total PMN, LYM, MAC and EOS counts in the BAL of mice infected with A2 and mice vaccinated with FI-Vero cell lysate and then challenged with RSV A2 (FI-Vero+A2) at day 5 post-challenge are shown. Significance was calculated using a Student's <i>t</i> test, comparing mice in each group to mice vaccinated with FI-A2 alone and challenged with RSV. * <i>p<0</i>.<i>05</i>.
