Foals can then be vaccinated for tetanus when 3 months old with the two injections. Vaccinating too early can interfere with the foal's natural immune development.

If the foal's dam wasn't immunized before foaling, she should get an annual booster or the two injections, if her tetanus immunization history is unknown.
Older horses are also prone to wounds that can lead to tetanus.
