Abstract A vaccine for immunization of swine against Trichinella spiralis "T. spiralis" wherein the immunogenic substance is inert newborn larvae of T. spiralis emulsified with a suitable adjuvant. The vaccine induces greater than 60% immunity in swine and offers a novel approach to the control of swine trichinosis. Preferably, the inert newborn larvae preparation is emulsified with Freund's complete adjuvant.
