Vaccination against Foot and Mouth Disease (FMD) presents challenges because the disease is caused by a virus that has multiple serotypes and subtypes. As a result, there is not a single serotype; vaccination must account for the variety of strains present in different regions. This variability complicates the development of a universal vaccine, making it incorrect to say that vaccination is simple.

The other statements about FMD are accurate. All cloven-hoofed animals, such as cattle, sheep, goats, and pigs, indeed have susceptibility to the disease, which is a characteristic of the pathogen. FMD can also reach morbidity rates of up to 100% among herds, indicating that the entire population can become affected. Additionally, FMD is highly contagious, with the potential for rapid spread among susceptible populations, heightening its impact on livestock health and agriculture.
