Vaccinated yearlings , two-year-old and in-foal pony mares with appropriate controls were exposed to aerosols of a subtype 1 virus one to two months after two or three vaccinations; all became infected. No obvious differences in the febrile responses, clinical signs and subsequent abortions were found between vaccinated and control mares. All vaccinated yearlings and two-year-old ponies developed a febrile respiratory disease but this was less severe than that suffered by the controls and the amounts and duration of virus shedding were reduced.
接种疫苗的一岁马、两岁马和怀孕母马及其相应对照，在进行两到三次疫苗接种后的一到两个月，暴露于1型病毒的气溶胶中；所有马匹均被感染。接种疫苗的母马和对照母马在发热反应、临床症状及随后的流产情况方面未发现明显差异。所有接种疫苗的一岁马和两岁马都出现了发热性呼吸道疾病，但症状比对照马轻，病毒排出量和持续时间也有所减少。
