Question: Hi there. You did herd health for us earlier this spring. I was just curious...do we need a booster shot for the West Nile?
Answer: Hi E, If your horse has previously been vaccinated (in the past 2-3 years) you don't need a booster. If this is their first vaccine, yes you need to boost at this time. Thanks -Dr.D.
