Vaccination schedule
A horse’s vaccination programme should be based on the risk of disease
for the horse and also the economic consequences of an outbreak. In general,
the more a horse is in contact with other horses the greater its risk of contracting
strangles.
The basic vaccination schedule is two submucosal vaccinations
four weeks apart.* Horses in high-risk situations
should be revaccinated with a single dose every three months. For horses in medium-risk situations
revaccination every six months rather than every three months can be considered.
If horses are revaccinated every
six months, a prompt booster
with a single dose should be given if an outbreak of strangles occurs more
than three months after the last booster (see table). There is generally no need to vaccinate horses in low-risk situations.
