The National Medical Products Administration (NMPA) of China has granted approval for clinical research on the 21-valent pneumococcal polysaccharide conjugate vaccine, a collaboration between Sanofi China and SK Bioscience. This vaccine represents a groundbreaking achievement as it is the world's first 20-valent or higher pneumococcal polysaccharide conjugate vaccine specifically designed for infants and young children to enter Phase III clinical trials, following the successful completion of earlier Phase III trials across various global regions.
