Viral RNA levels, clinical chemistry, and immunology
YFV, infection
INFECTION, VIRUS
The YFV vaccine causes a mild infection, often with detectable virus in circulation. As a safety-related assessment, we measured serum YFV NS5-RNA levels in all cohorts vaccinated with the YFV vaccine in order to assess if concomitant vaccination had any effects on YFV viral replication. Across all study cohorts, most study participants receiving the YFV vaccine had detectable levels of YFV NS5-RNA seven days after vaccination (
