Evaluation for foot-and-mouth disease vaccines in South Korea by the test for national lot release

Foot-and-mouth disease (FMD) causes economic problems in livestock industry because of fast spread and inducing low productivity. FMD outbreaks occurred in South Korea over the period from 2000 to 2019. Vaccination is the most practical and effective means of controlling or preventing these outbreaks, and a national vaccination policy has been in place for all FMD-susceptible animals since 2010. To prevent and control of FMD, South Korea has been using vaccines imported from the United Kingdom, Argentina, and Russia. The Animal and Plant Quarantine Agency of South Korea oversees continuous quality control of imported FMD vaccines. FMD vaccines were evaluated characteristics, sterility, pH, inactivation, safety, potency test by Korean FMD vaccine standard assay (Test for National Lot Release). The 6 company vaccines (A~F) were used Test for National Lot Release by each method. We evaluated quality of each FMD vaccine from 2015 to 2019. All batch of vaccine showed good quality control and were passed the Test for National Lot Release. The serotypes of vaccine are increasingly changing to multiple vaccine because the FMD was outbreak by various serotype virus in South Korea. Furthermore, this data may be useful as a basis for ensuring the quality of FMD vaccines and for base data to manage them. Additional study is required to simple approach for rapid evaluation of quality and antigen content identification in vaccines.
