Perivascular eosinophils in the lungs of mice sensitized to RSV-F, RSV-G, or RSV-G/22K glycoproteins. Mice were primed with the indicated recombinant vaccinia virus 3 wk before intranasal challenge with RSV. Mice were killed 5 d later and lung sections were stained for eosinophils. Eosinophils around the blood vessels were counted and the lengths of the vessels were measured by micrometer. Each data point represents cell counts from individual animals.
