Foot and mouth disease (FMD) is a highly contagious viral-induced disease of cloven-hoofed animals that results in serious economic consequences in affected countries that have a significant international livestock trade. Currently disease control measures include inhibition of susceptible animal movement, slaughter of infected and susceptible in-contact animals, disinfection, and possibly vaccination with an inactivated whole virus antigen. However, there are a number of problems with use of the current vaccine in outbreaks in countries which have been previously free of FMD. As a result countries which vaccinate face a longer delay in regaining FMD-free status than countries which do not vaccinate but rather slaughter all infected or susceptible in-contact animals. Researchers have been attempting to develop both new FMD vaccines to overcome the limitations of the current inactivated vaccine as well as methods to more rapidly induce a protective response. In this manuscript I discuss the most effective new FMD vaccines and novel antiviral strategies that are currently being examined.
