Vaccines against cysticercosis and hydatidosis: foundations in taeniid cestode immunology.

Recombinant oncosphere antigens have been used in the development of effective vaccines for the prevention of cysticercosis caused by Taenia ovis, Taenia saginata, Taenia solium and hydatid disease caused by Echinococcus granulosus. These vaccines were developed utilizing information gathered from numerous researchers over some 60 years which had established many of the principals concerning immunity to taeniid cestodes in their intermediate hosts. Australian scientists, or scientists with close Australian connections, made seminal early contributions to the understanding of cestode immunology that provided the foundations for more recent application of recombinant DNA methods and the development of practical vaccines. Here, some particular contributions to the field are highlighted from Drs. Michael Gemmell, Michael Rickard, David Heath and Graham Mitchell together with a précis of the recent progress in vaccine development, particularly for prevention of cysticercosis due to T. solium.
