Zhuoyi Biological

Zhuoyi Biological is a Chinese vaccine company focused on the research, production, and commercialization of human vaccines. The company is best known for its freeze-dried human rabies vaccine produced in Vero cells, which appears to be its principal marketed product and main revenue driver. Publicly available company and IPO-related materials indicate that Zhuoyi integrates R&D, manufacturing, and sales, with expansion plans centered on rabies-vaccine production capacity and broader vaccine R&D. The company appears to be private as of April 8, 2026, although it has pursued an A-share IPO in China. Zhuoyi Biological is best characterized as a commercial-stage vaccine manufacturer rather than a broad platform biotech.
