While vaccinations are particularly topical as conversation fodder this year (will you get the Pfizer or the AZ?) they have played an important part in human and animal disease prevention for over 200 years.

Farm biosecurity has three key aims: Prevent entry of disease, Contain spread if a disease does arrive on farm, and Minimize the impact of disaese if/when it occurs.
