There is '''no treatment''' for chicks infected with avian encephalomyelitis (AE). Affected chicks that that survive are considered unlikely to be profitable <ref name="Calnek, 2003" />. Surviving chicks will be '''immune to AE for life'''.

In regions where AE is prevalent an effective way of preventing AE is to '''vaccinate pullets''' several weeks before they come into lay.  Vaccination protects the flock from a reduction in egg production and prevents vertical transmission of the virus to chicks by providing the chicks with a sufficient level of maternal derived antibodies.  There are live and attenuated vaccinations available which can be administered in '''drinking water''' or as an '''eye drop''', the latter being more effective. vaccination by eye-drop of only 10% of a flock gave the same results as drinking water application <ref name="Shafren, 1992">Shafren, D.R., Tannock, G.A., Groves, P.J.
