Immunity
Recovered animals develop homologous immunity. However infections with antigenically unrelated species or strains may require further treatment with Butalex.

Caution
Theiriosis has severe depressant effects on the immune system. Therefore it is recommended that any vaccination be delayed until the animal has recovered.
