CanSino Biologics (HKG:6185, SHA:688185) initiated a phase 1/2 trial of its 24-valent pneumococcal conjugate vaccine, a broad-spectrum shot designed to prevent infections caused by 24 pneumococcal serotypes, according to a Tuesday filing with the Hong Kong bourse.
The trial will evaluate the vaccine in subjects aged two months and older for the prevention of pneumococcal infections, which can cause diseases such as pneumonia and meningitis.
The new product could expand coverage beyond the company's existing 13-valent pneumococcal vaccine, which was approved in China in June 2025.
The firm said there were currently no 24-valent pneumococcal conjugate vaccines available on the global market.
