Juvenile chinook salmon in fresh water were vaccinated either orally or parenterally with heat– or formalin–killed bacterins prepared with Vibrio anguillarum. Subsequent exposure to naturally occurring vibriosis in the marine waters of Puget Sound (Washington State) indicated that no protection resulted. It was demonstrated, however, that protection could be achieved with the passive transfer of immune serum.
