No evidence of vaccine virus transmission was found in two studies where Wistar RA 27/3 rubella vaccine was administered intranasally. Vaccine was immunogenic in all of 23 vaccinated children in one study, while in the other only 5 of the 11 vaccinees developed antibody. The reduced seroconversion rate in the latter study appears to have been caused by one or a combination of factors, including the vaccination technique, the presence of infective nasal conditions in vaccinees and the titre of vaccine used.
在两项鼻内接种Wistar RA 27/3风疹疫苗的研究中,未发现疫苗病毒传播的证据。在一项研究中,23名接种疫苗的儿童均产生了免疫反应,而在另一项研究中,11名接种者中只有5人产生了抗体。后一项研究中血清转化率降低似乎是由一个或多个因素共同作用导致的,这些因素包括接种技术、接种者存在感染性鼻腔疾病以及所用疫苗的效价。
