The strain specificity of vaccination with ultra violet attenuated cercariae of the Chinese strain of Schistosoma japonicum

Mice vaccinated with ultra violet (u.v.) attenuated cercariae of the Chinese mainland strain of S. japonicum were resistant to homologous challenge, but were not resistant to challenge with the Philippine strain of S. japonicum. Thus vaccination using u.v. attenuated S. japonicum cercariae is strain specific.
