Eosinophilic recruitment in thermally injured older animals is associated with worse outcomes and higher conversion to full thickness burn.

•Older mice are more likely to convert from partial to full thickness burn injury.•Localized EOTAXIN expression is increased in both old and young mice after burn.•Older mice have elevated baseline levels of systemic EOTAXIN.•Eosinophil populations are elevated in the burns of older mice as compared to young.
