Chinese researchers report positive results with a vaccine against African Swine Fever.
The Harbin Veterinary Research Institute conducted trials with 3,000 pigs, some of them piglets and others sows.
The results indicate that at doses 100 times greater than usual, the vaccine generated an 80 percent immune response.
The researchers report that during the 20-week observation period, the vaccinated pigs showed no clinical abnormalities or signs of infection.
