    Technology Brief -- Chiron Corp.:
    Vaccine Prototype Blocks
    Hepatitis in Some Chimps

    Chiron Corp., Emeryville, Calif., said a prototype of a vaccine
 developed in a joint venture with Ciba-Geigy Ltd.  prevented
 hepatitis infection in a group of chimpanzees.
    Five of seven chimpanzees tested didn't contract the hepatitis C
 virus after being given a vaccine developed by Biocine Co., the
 joint venture formed with Switzerland's Ciba-Geigy, Chiron said.
    "This study provides data that may allow Biocine to initiate
 human trials in 1994," Dino Dina, Biocine president, said.
    Biocine is developing vaccines for preventive or therapeutic use
 against herpes, AIDS and other infectious diseases.
