Foot-and-mouth disease (FMD) is the most contagious disease of mammals. The use of inactivated vaccine can be chosen to prevent or control FMD. However, vaccination against one serotype of FMDV doses not cross-protect against other serotypes and may not protect fully against some strains of the same serotype. Appropriate selection of vaccine strain is an important element in the control of FMD. The immunity of vaccine antigens should be matched against newly circulating viruses. The phylogenetic analysis of serotype Asia1 reported from China, Mongolia, North Korea and Russia since 2005 shows that they are all classified into genetic group V, but the strain, Asia1/Shamir (ISR/89) which have been used as a vaccine strain in Korea, is clustered into different genetic group. So, in this study the serological relationship between the isolate (Asia1/MOG/05; MOG) and the Shamir stain was determined by ELISA and virus neutralization test. Even though the matching value of the virus (MOG) against the vaccinated sera in target animals was not so high, the vaccinated animals elicited antibodies enough for protection after vaccinated once or twice. Conclusively, we suggest that the vaccine containing Asia1/Shamir antigen could protect the genetic group V strains circulating in East Asia currently if vaccinated twice or the more.
