Protective immune response to liposome adjuvanted high potency foot-and-mouth disease vaccine in Indian cattle.

Background: Foot-and-mouth disease (FMD) vaccines applied for prophylactic use in endemic areas provide short-lived immunity requiring regular boosters. Indian FMD control program recommends twice a year vaccination. Development of high potency vaccines that provide better immune response can singificantly contribute to control programme by reducing the frequency of vaccination.
