Jiang Rensheng moved from teaching and public-health work into the vaccine business, built Chongqing Zhifei Biological Products into a listed pharmaceutical company, and created his fortune through ownership of that operating platform. [1][2][3]
His career began outside private enterprise
Forbes says Jiang worked as a primary-school teacher and later as a government health official before striking out on his own. The reviewed record therefore starts with salaried public-sector work rather than an inherited pharmaceutical business. [1]
Zhifei's company history dates its entry into the biological-products industry to 2002, when a predecessor business was integrated into Chongqing Zhifei Biological Products. The company then added research, manufacturing and distribution subsidiaries. [2]
The company says its first self-developed meningococcal vaccine received market approval in 2006, followed by another vaccine in 2007. Those milestones show Zhifei building proprietary products alongside its distribution activities. [2]
Vaccines and distribution became the fortune-producing platform
Forbes identifies Jiang as chairman of Shenzhen-listed Zhifei and notes the company's long-running vaccine distribution relationships as well as its internally developed products. Zhifei's own materials describe an integrated research, production, sales and distribution business. [1][3]
The reviewed evidence supports a primarily self-created fortune. Jiang moved from education and public health into private enterprise, built ownership in a vaccine company and remained chairman as Zhifei expanded into a large listed biopharmaceutical group. [1][2]
