Group 3: Competitive Landscape - Wantai Biological's nine-valent HPV vaccine is the first domestically produced version and the second globally, but it will face stiff competition from Merck's Gardasil 9 and other emerging products from companies like Shanghai Bowei and Beijing Kanglaweishi [2][9]. - The market for HPV vaccines is expected to become increasingly competitive, with several companies developing higher-valent vaccines, which may further challenge Wantai Biological's market position [9].
