The use of vaccines on animals is common throughout the world yet
efficacy in disease prevention is scant. A new study shows that vaccines
used by commercial fish farmers are not protecting fish from disease
.The study
was compiled by researchers at the University of Waterloo, the
Pontifical Catholic University of Valparaiso and Chile's University of
Valparaiso. It showed vaccinated fish tend to show more symptoms when
contracting diseases, with the health impacts and ultimately deaths
occurring as if they'd never received a vaccine.
