sentences:  This led to the development of highly effective, recombinant vaccines against cysticercosis in cattle due to "Taenia saginata" (TSA9/TSA18) and in pigs due to "Taenia solium".In collaboration with Dr David Heath at the Wallaceville Animal Research Centre in New Zealand, he and his colleagues also developed the EG95 recombinant vaccine against cystic echinococcosis (hydatid disease).The "E. granulosus" and "T. solium" vaccines could potentially have been developed for use directly in humans, however due to the parasites’ medical impact being restricted largely to developing countries, funding was not forthcoming, hence they were developed for use in the parasites’ natural animal intermediate hosts.
