USA, Washington. Researchers in the US are said to have taken a decisive step forward in the development of a vaccine against African swine fever (ASF).
The Plum Island Animal Disease Center, which is affiliated with the US Department of Agriculture, announced that in a trial with live pigs, the vaccine candidate ASFv-G-I77L achieved the same vaccination success when administered orally or nasally as when injected intramuscularly reported the German site SUS. The researchers demonstrated the efficacy of this vaccine, which is derived from a highly virulent virus strain from Georgia, as early as the end of 2019.
The new trial results give great hope in that no injection vaccine can be used to control ASF in wild boar herds. Now the scientists want to make the vaccine candidate into a bait form that is attractive to pigs and conduct further field trials. This will include testing whether the vaccine is as safe in feral pigs as it is in the domestic pigs tested.
