On 6 farms with a history of EHV-1 abortions the overall prevalence of losses due to abortion, stillbirth and neonatal foal mortality during 5 foaling seasons preceding the introduction of vaccination against EHV-1 were compared with corresponding data for 8 subsequent seasons in which all horses were immunized with a modified live EHV-1 vaccine. Although both sporadic and epizootic EHV-1 abortions occurred in immunized mares, the numbers of foetal and neonatal foal losses decreased significantly (chi 2 = 15.75; p less than 0.001) from 11.8% (343 of 2897 pregnancies) during the seasons 1969-1973 to 8.9% (334 of 3763 pregnancies) in the years 1975-1982 during which EHV-1 vaccinations had been carried out.
在6个有马疱疹病毒1型（EHV-1）流产病史的农场，将引入EHV-1疫苗接种前5个产驹季节因流产、死产和新生驹死亡率导致的损失总体患病率，与随后8个季节的相应数据进行了比较，在随后的8个季节中，所有马匹都接种了改良活EHV-1疫苗。尽管在接种疫苗的母马中既发生了散发性也发生了流行性EHV-1流产，但胎儿和新生驹损失的数量从1969 - 1973年季节期间的11.8%（2897次妊娠中有343例）显著下降（卡方= 15.75；p小于0.001）至1975 - 1982年期间进行EHV-1疫苗接种时的8.9%（3763次妊娠中有334例）。
