Lung virus loads and body weight changes after respiratory syncytial virus (RSV)-A2 challenge. The experiment was repeated twice. A, Lung virus load. Lungs from individual mice in each group (6 mice) were collected on day 4 postchallenge, and lung virus loads (number of plaque-forming units [PFU]) in each mouse were determined. The limit of virus detection is 50 PFU/mL. B, Comparison of lung virus loads between RSV-F and RSV-G viruslike particles (VLPs). The lower scale of the Y axis was used to see differences in lung virus loads between RSV-F and RSV-G VLP immunization. C, Body weight changes. Vaccinated mice (6 mice) were challenged with live RSV-A2 virus. The body weights were monitored daily in which 100% body weight was seen at day 0.
