Hualan Vaccine has recently received the Approval Notice for Drug Clinical Trial from the National Medical Products Administration for its innovative freeze-dried Haemophilus Influenzae Type b (Hib) conjugate vaccine. This vaccine, crafted through the conjugation of Hib capsular polysaccharide with tetanus toxoid protein, leverages freeze-drying technology to elicit a robust immune response and offer comprehensive protection. Furthermore, the company is actively developing a combined diphtheria, tetanus, and pertussis vaccine, which incorporates the Hib vaccine as an integral component. The intricate and time-consuming process of vaccine development underscores Hualan's commitment to advancing healthcare solutions.
