Anti-tetanus immunisation in orienteers.

The present state of anti-tetanus immunisation amongst orienteering runners from 20 countries was assessed by questioning the orienteers as to when they last received an anti-tetanus injection. The results demonstrate that approximately 55% were within five years of their last injection, 18% were within 5-10 years, 12% were greater than 10 years and a further 15% did not know when or had never had an anti-tetanus injection.
