MANILA, Philippines — A majority of hogs included in the controlled vaccination against African swine fever (ASF) remain in good health and have developed antibodies, according to the Department of Agriculture.
The DA said results of ELISA or enzyme-linked immunoassay tests conducted on the hogs showed the presence of ASF antibodies in some pigs.
“The test results indicated the hogs are building immunity. All remaining pigs are healthy and under close observation,” DA Assistant Secretary Constante Palabrica said.
Earlier, the DA said five of 41 pigs inoculated with ASF vaccine died of pulmonary diseases and not of the virus.
The DA started the vaccination trial in Lobo, Batangas in a bid to control the spread of ASF, which has been hurting the swine industry.
The agency said that vaccination is only a part of a broader ASF control strategy, noting that comprehensive biosecurity measures are needed to curb the spread of the virus.
“Honest and timely reporting from farmers is essential for the program’s success,” Palabrica said.
