Vietnam said on Wednesday it had successfully developed a vaccine to fight African swine fever.
It aims to be the first country to commercially produce and export an African swine fever vaccine.
Vietnam lost 20per cent of its pigs after the first outbreak there in February, 2019.
It originated in Africa before spreading to Europe and Asia and has killed hundreds of millions of pigs globally, hitting China particularly hard.
"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.
Its safety and efficacy was confirmed by the Agricultural Research Service under the U.S. Department of Agriculture, Tien said.
"This success opens great expectations and the room to export African swine fever vaccine produced in Vietnam is huge," Tien added.
He did not provide a timeframe for when the vaccine could be exported or estimate of Vietnam's production capacity.
