Dihydrothioctic acid inactivated Habu snake toxoid was injected subcutaneously into 2846 people of Kamimotobu Village, Ryukyu Islands. They received shots of 0.5ml. of toxoid, containing 2.5mg. of Habu snake venom and DHTA, at the interval of two weeks. Main local reactions were slight localized pain which continued for a week, and slight swelling. Generalized symptoms such as fever were very few. Effectiveness of the toxoid on Habu snake bite will be further investigated by means of increasing the volunteers who wish the shots.
