Genetic vaccination against murine cysticercosis by using a plasmid vector carrying Taenia solium paramyosin.

A plasmid vector carrying the immunoprotective amino-terminal fragment of Taenia solium paramyosin (VW2-1) was designed for genetic vaccination studies. Mice that were genetically immunized with VW2-1 and challenged by intraperitoneal inoculation of Taenia crassiceps cysticerci showed 43 to 48% reductions in the parasite burden, values which were similar to values obtained previously when the recombinant protein was used.
