This tool projects population-level immunity against FMDV in livestock by using vaccination data and antibody levels. It helps veterinary officials plan and assess vaccination campaigns to prevent outbreaks.

The model divides the population into groups (such as susceptible, infected, recovered, and vaccinated) and assumes that all animals mix equally. It presumes that vaccination gives immediate protection and uses a decay function to model gradual immunity loss. These assumptions help simplify real-world complexities while providing useful guidance for vaccination planning.

By inputting your local vaccination coverage and seroprotection data, the tool estimates the level of immunity across your livestock population. It helps identify the minimum vaccination coverage needed and optimal vaccination timing to reduce the risk of an FMD outbreak.
