What is the initial vaccination schedule for Tetanus in horses?

The correct answer is based on the established vaccination protocol for tetanus in horses, which emphasizes the importance of building initial immunity and maintaining it over time. Tetanus vaccination typically begins with two doses that are administered within a few weeks of each other. This two-dose series is crucial because it helps to establish a strong immune response in the horse. After the initial vaccinations are completed, a single booster is given annually to maintain immunity.

This schedule is designed to ensure that horses develop adequate protection against tetanus, which is a serious and potentially fatal disease caused by the toxin produced by the bacterium Clostridium tetani. Regular annual boosters are important because they help to reinforce the horse's immunity and ensure that it remains protected throughout its life.

In summary, the method of initially vaccinating with two doses followed by annual boosters effectively establishes and sustains immunity, which is why this vaccination schedule is the standard practice for preventing tetanus in horses.
