When should I give my horse vaccines?
The timing of vaccines is based upon several things including the age of your horse, how often they travel or see other horses and what their immune system is like. In general, spring vaccines can be given between March and May. It is best to give them prior to the mosquito population hatching, so that they can be protected from the mosquite borne diseases (EEE, WEE and West Nile Virus). Their fall vaccines should be scheduled 6 months from the spring vaccines (September to November).
