Vaccination is recommended to help avoid this serious condition.1,3

You can vaccinate your horse against strangles with Equivac S or Equivac 2 in 1, available from your vet.

Your foal can get this vaccination from 3 months of age. Initially, it is given as 3 doses no less than 2 weeks apart, followed by annual boosters to maintain immunity. Increased protection against strangles may be obtained by giving booster doses more frequently, for example every 6 months
