March 29, 2025 at 06:15 AM UTCBy FilingReader AI

Chongqing Zhifei Biological Products (SZSE:300122) announced that its subsidiary, Zhifei Green Bamboo Pharmaceutical, has received acceptance from the National Medical Products Administration for its clinical trial application for its adsorbed tetanus vaccine (CXSL2500250). Zhifei Green Bamboo can proceed with clinical trials if no objection is received within 60 days. The vaccine targets tetanus, a severe and potentially fatal disease caused by the bacterium Clostridium tetani. According to the company, the new vaccine uses column chromatography for antigen purification, resulting in higher purity and better batch consistency compared to traditional salt precipitation methods. There are currently 12 adsorbed tetanus vaccines on the market in China. Zhifei anticipates that a successful trial and product launch will enhance its adult vaccine offerings and strengthen its market competitiveness.
