The best time to vaccinate is 5 months prior to the anticipated outbreak period. This is due to the fact that it takes 5 months for the horse to build immunity to the highest level from the vaccine. It is also the best time as the midge population will be at low levels so these will be no risk to the horses. The anticipated outbreak is most severe in March according to our data, so the ideal time to vaccinate is around November.
