[Studies on the immunity status against tetanus in Rhine-Hesse].

Immunity to tetanus in the population of Rhine-Hesse deteriorates with increasing age. A reduction of both the average antibody concentration and the duration of immunity after the last vaccination can be found. The percentage of unprotected people also increases with age. Especially women have a poor protection against tetanus. The immunity to tetanus should therefore be checked in elderly persons and in women irrespective of a possible lesion.
