Respiratory infections caused by a herpes virus are what we call "colds" in humans. There is a vaccination for Equine Herpes Virus and, if recommended, it is given 2-4 times a year depending on risk factors and the brand of vaccine used. EHV vaccination is a risk-based vaccination in the US and not recommended for all horses.
