Yu Yongxin, a key figure in China's virology and biological products research, dedicated his career to tackling major infectious diseases such as Japanese encephalitis, hemorrhagic fever with renal syndrome (HFRS), and rabies. He led the development of the SA14−14−2 live−attenuated Japanese encephalitis vaccine, which marked a breakthrough in vaccine safety, quality assurance, and international recognition. Yu also organized the establishment of evaluation systems for HFRS vaccines and promoted technological improvements across various vaccine platforms, enabling the transition of rabies vaccines from traditional methods to cell culture−based production. Through his contributions in standardization, international collaboration, technology transfer, and talent cultivation, he helped build a comprehensive system encompassing vaccine research, testing, and dissemination—providing strong support for the advancement of China's vaccine industry and public health infrastructure.
