Plain-English summary
Several miniature horses in Canada died after receiving a live spore anthrax vaccine during an outbreak. The deaths were linked to a serious immune reaction called immune-mediated vasculitis, which caused inflammation of the blood vessels. Other horses that were vaccinated in different areas showed similar symptoms and findings upon examination after death. This situation highlights the potential risks associated with certain vaccines, even in healthy animals.

Abstract
During a widespread anthrax outbreak in Canada, miniature horses were vaccinated using a live spore anthrax vaccine. Several of these horses died from an apparent immune-mediated vasculitis temporally associated with this vaccination. During the course of the outbreak, other miniature horses from different regions with a similar vaccination history, clinical signs, and necropsy findings were found.
