Protection of mice against heterosubtypic challenge. Percent weight loss (A) and lung virus titers (B) were measured in A/WI/05 (H3N2)-immunized mice, 7 days after infection with A/PR/8/34 (H1N1). Groups of mice were vaccinated IM with live and heat-treated whole virus. Control groups included mice without prior vaccination and a group of mice infected IN with live A/WI/05.
