Tetanus toxoid became commercially available in 1938, but was not widely used until the military began routine vaccination in 1941. Routine administration of tetanus toxoid was recommended by the AAP in 1944. Most World War II military personnel received at least one dose of tetanus toxoid, but civilian use, particularly for adults, did not increase until after the war. You should not assume the tetanus vaccination status for any person based on their age alone. Only a written record is acceptable proof of immunization. People without documentation should be assumed to be unimmunized.
