Scientists welcome ‘promising’ ASF vaccine findings

Scientists have welcomed what they describe as the first report of a ‘promising vaccine’ against ASF virus in wild boar.
The scientists from Spain demonstrated that oral immunisation of wild boar with an attenuated ASF virus of genotype II isolated in Latvia in 2017 conferred 92% protection against challenge with a virulent ASF virus isolate.
This protection translated to animal survival, but also to the absence of ASF-compatible clinical signs, pathological findings, and virus detection in target tissues.
“This is, to our knowledge, the first report of a promising vaccine against ASF virus in wild boar by oral administration,” the researchers said in an article in the Frontiers in Veterinary Science journal.
“Further studies should assess the safety of repeated administration and overdose, characterize long-term shedding and verify the genetic stability of the vaccine virus to confirm if (the vaccine) Lv17/WB/Rie1 could be used for free-ranging wild boar in ASF control programs.”
The researchers describe ASF as the most significant threat to the pig industry worldwide, having spread to more than 55 countries on three continents...
Veterinarians Say An Effective ASF Vaccine Development Will Take Time

Researchers in Switzerland have developed a new oral vaccine used in Wild Boars they say has been effective in vaccinating against African Swine Fever. The findings have been published in Frontiers in Veterinary Science. National Pork Producers Council Chief Veterinarian Dr. Liz Wagstrom says she’s read about the vaccine and the jury is still out on its effectiveness.
She says having an oral vaccine for use against ASF would be good. Wagstrom says it will take time to get an ASF vaccine that will work in commercial hogs.
SDSU Extension Veterinarian Dr. Russ Daly says it’s likely the first time an oral vaccine has been developed and he also thinks it’ll take time to get a good vaccine out for ASF prevention.
He’s hoping they can come up with an ASF vaccine that can first be used in China to stop the diseases spread...
