Vietnam has developed an African swine fever vaccine for pigs in partnership with the United States, and is aiming to become the first global commercial exporter, an official said.

Figure 1 shows that the virus, harmless to humans, decimated hog populations in Asia after it was detected in Vietnam in 2019, with millions of the animals culled following outbreaks in Mongolia, Cambodia, Hong Kong and mainland China. [1]

"This is a milestone of the veterinary industry," deputy agriculture minister Phung Duc Tien said in a statement. "With immunity lasting six months, the vaccine will be a shield for hog-raising industry and pig production globally."

The vaccine has been in development since November 2019 in partnership with United States experts, with five clinical trials held. [2]

"We are confident to produce pig swine fever vaccine for domestic prevention and will also aim at export," he said.

However, officials did not give a timeframe for the vaccine's rollout or any indication of Vietnam's capacity to produce it at scale.

From 2020, Vietnamese researchers worked with United States scientists on the NAVET-ASFVAC jab, Tien said.

He said the Agricultural Research Institute of the US Department of Agriculture had "sent an official letter to the Department of Animal Health of Vietnam confirming that the NAVET-ASFVAC vaccine is safe and effective".

Five Vietnamese clinical lab trials "showed 100 percent of vaccinated pigs were protected against toxicity in the laboratory", Tien said. An official circulation license for Vietnam would be issued Friday at a ceremony launching the jab, the Department of Animal Health said. [3]
