USDA announces ASF candidate vaccine

 

 

A candidate vaccine, known as ASFV-G-DI177l, efficiently protects against African swine fever, the United States Department of Agriculture (USDA)announced on September 30.

 

USDA’s Agricultural Research Service (ARS) published new research that highlights a new vaccine candidate that has been shown to prevent and effectively protect both European and Asia bred swine against the current circulating Asian strain of the virus.

 

ASF has not reached North America, but it's getting closer. The disease arrived this year on the Caribbean island of Hispaniola, shared by Haiti and the Dominican Republic.

 

ARS reported that the vaccine candidate is effective in all swine by the fourth week after vaccination. According to the agency, "scientists have developed a vaccine candidate with the ability to be commercially produced while still maintaining the vaccine efficacy against Asian ASF virus strains when tested in both European and Asian swine breeds."

 

"We are excited that our team’s research has resulted in forming vaccine candidates that are able to prevent and protect different swine breeds against the current ASF virus," said ARS administrator Chavonda Jacobs-Young. "Vaccine candidates could play an important role in controlling the outbreak threatening global swine health."

 

Published in the Transboundary and Emerging Diseases journal, the vaccine research shows that ARS scientists have developed a vaccine candidate with the ability to be commercially produced while still maintaining its vaccine efficacy against Asian ASF virus strains when tested in both European and Asian swine breeds.

 

"We are excited that our team's research has resulted in promising vaccine results that are able to be repeated on a commercial level, in different pig breeds and by using a recent ASFV isolate," said ARS researcher Douglas Gladue. "This signals that the live attenuated vaccine candidate could play an important role in controlling the ongoing outbreak threatening the global pork supply."

 

"This is a major step for science and agriculture," said ARS researcher Manuel Borca. "We are working carefully to see our vaccine candidate commercialised through the joint efforts of the US government, and our commercial partner, the Navetco National Veterinary Joint Stock Company."
