Why is the price of domestic hepatitis B vaccine still different? There are more than 60 kinds of vaccines in Dalian, and only 20 kinds of traditional Chinese medicine. . . .

Domestic hepatitis B vaccine is priced independently by enterprises due to different production processes, and the prices are different. The genetically engineered hepatitis B vaccine of Dalian Hanxin Biopharmaceutical Co., Ltd. is "recombinant hepatitis B vaccine (Hansen yeast)", and the genetically engineered hepatitis B vaccine of North China Pharmaceutical Jintan Biotechnology Co., Ltd. is recombinant hepatitis B vaccine (CHO cell).
