VN antibody titers of 3-year-old horses inoculated with EHV-1 vaccines. Sera were collected from 3-year-old horses (n = 50, each period) inoculated with EHV-1 vaccines. In 2013–2014, horses were treated with the inactivated vaccine three times at approximately 1-month intervals. In 2014–2015 and 2015–2016, horses were vaccinated with live vaccine twice with an interval of approximately 1 month. The VN titers were measured for the sequential serum samples, and were expressed as GM titers. a and b, significant differences (P < 0.05) between the different symbols
