皮内试验是诊断某些病毒性疾病的一种高度敏感性的方法。按等资料,应用流感抗原作皮肤试验可获得93％的阳性结果;在其他急性呼吸道感染疾患仅28％出现阳性的皮肤反应。本文对多次接种流感活疫苗的供血者于注射高度精制的流感抗原后的皮肤反应,及对志愿者实验性流感的发病情况进行了研究。采用流感病毒A_2/香港/68/21和B/苏联/69/17毒株制成高度纯化的流感疫苗,以结核菌素注射器 Intradermal testing is a highly sensitive method of diagnosing certain viral diseases. Press and other information, the application of influenza antigen for skin test can get 93% of the positive results; in other acute respiratory infections only 28% positive skin reaction. In this paper, the skin reaction after multiple inoculation of the live influenza vaccine against highly purified influenza antigen and the incidence of experimental influenza in volunteers were studied. Highly purified influenza vaccines were made using the influenza A_2 / Hong Kong / 68/21 and B / USSR / 69/17 strains, with tuberculin syringe
