To evaluate possible persistence of 17D yellow fever vaccine, we tested urine samples from 44 healthy recipients of yellow fever vaccine at varying times up to one year after vaccination. Urine samples from two vaccine recipients had detectable yellow fever virus RNA. The time since vaccination was reported as 21 days for one sample and 198 days for the other sample. These results suggest that yellow fever vaccine virus might persist for at least 6 months after vaccination in some people.
为评估 17D 黄热病疫苗的持久性，我们检测了 44 名健康黄热病疫苗接种者在接种后长达一年的时间内的尿液样本。两名疫苗接种者的尿液样本中检测到了黄热病病毒 RNA。其中一份样本的接种时间据报告为 21 天，另一份样本为 198 天。这些结果表明，在某些人身上，黄热病疫苗病毒至少可以在接种后持续存在 6 个月。
