Frequently Asked Questions (FAQs)

1) How accurate is your information on the pre-warning map, i.e. estimated percentage listed to actual cases? I've heard about several horses that had AHS (just hear say), but they don't seem to be listed. 2) I use to vaccinate in October/November, but last year my vet told me that I must vaccinate earlier, in August. Is this correct. Also heard (not from vet) that if you vaccinate to early then you get old vaccine from previous year? So when is the best time to vaccinate?

We know that AHS is underreported nationally and we think that we will possibly get approx 50% this year but this is just a guess. It is however improving year on year, as the awareness of reporting is greater. If you hear of cases please insist that they are reported.

 

The best time to vaccinate is 5 months before the anticipated outbreak in your area. It takes the horse’s immune system 5 month to reach its peak levels of immunity from the vaccine. Each area seems to be slightly different however the peak outbreak time nationally is March. The other reason is that it will be the low vector activity period.
