Observation on the Efficiency of the Mongolian Gerbil Kidney Tissue Culture Inactivated Bivalent Vaccine for Hemorrhagic Fever with Renal Syndrome

摘要

The Z 10 and Z 37 strains of hemorrhagic fever with renal syndrome (HFRS) virus and the Mongolian gerbil ( Merions unguiculatus ) kidney cells were used to prepare the inactivated bivalent vaccine. A phase Ⅱ clinical trial use of this vaccine was made in 750 Chinese volunteers. The results showed that the side reaction rate was 2.5% and the sero-conversion rate of neutralizing antibodies against Hantaan and Seoul viruses in the inoculated volunteers were 87.6% and 96.3% respectively.
