China successfully undergoes trial of ASF vaccine

The Harbin Institute for Veterinary Research, part of the Chinese Academy of Agricultural Sciences (CAAS), published this week the results of the first trials of the African Swine Fever (ASF) vaccine, Xinhua News Agency reported.

Chinese scientists began the ASF vaccine testing on pigs in March. From April through June, clinical trials have been conducted at three base plants in Heilongjiang Province, Henan Province, and the Xinjiang-Uygur Autonomous Region. About 3,000 pigs have received the vaccine.

Vaccinated piglets develop without obvious adverse effects. No pathological changes were detected in the anatomy of vaccinated pigs, and obvious differences between the vaccinated group and the control group. The overall mortality rate decreased by 1%. Vaccinated pigs do not have ASF and are also not the virus carriers. Tests on the clinical vaccine efficacy are still ongoing. It is also necessary to check the effect of the drug in various enterprises and in various conditions, as well as to obtain a wider sample of data.
