Core Viewpoint - The recent visual competition between Merck and Wantai Biopharma at the Xiamen Vaccine Conference highlights the complexities of China's pharmaceutical industry as it seeks to break through technological barriers and challenge international monopolies [5][6]. Group 1: Technological Innovations - Merck's HPV nine-valent vaccine utilizes a globally pioneering technology platform that achieves correct folding of virus-like particles (VLPs), leading to its approval in 112 countries and over 300 million doses administered [5]. - Wantai Biopharma has developed a proprietary prokaryotic expression system that allows for effective VLP formation without complex glycosylation modifications, evidenced by its award-winning patent for a truncated HPV L1 protein [5][6]. - Both vaccines have undergone rigorous clinical validation, with Wantai's nine-valent vaccine demonstrating non-inferiority in neutralizing antibody levels and 100% efficacy against five new high-risk types, while Merck has the longest follow-up data of 13.6 years [5]. Group 2: Market Impact - The entry of Wantai's bivalent vaccine has significantly reduced the price of HPV vaccines in China from over 1,000 yuan to 329 yuan, making it more accessible and benefiting millions of women [6]. - Wantai's global sales have surpassed 80 million doses, reaching 23 countries, providing new options for vaccine distribution in developing nations [6]. - Wantai's technological breakthroughs have navigated the "patent jungle" in the HPV vaccine field, creating a viable path for independent innovation in China's biopharmaceutical industry [6]. Group 3: Marketing and Competition - The marketing strategies employed by both companies, particularly Merck's insinuation of defects in Wantai's product, could mislead consumers and undermine public trust in vaccines [7]. - Both companies have unique strengths that can complement each other in the market, with Wantai enhancing grassroots vaccination rates and Merck expanding the demographic reach of HPV protection [7]. - The HPV vaccine market in China remains underdeveloped, with low vaccination rates among eligible women, indicating that aggressive marketing battles may waste resources and distract from research and capacity building [7][8]. Group 4: Industry Transition - The Chinese pharmaceutical industry is at a critical juncture, transitioning from imitation to innovation, and from following to leading in global markets [8]. - Establishing competitive norms that align with industry characteristics while maintaining competitive vitality poses a challenge for regulators and companies alike [8].

Core Viewpoint - The China Vaccine Industry Association has issued an initiative to prohibit bidding below cost, aiming to promote high-quality development in the vaccine and related biological products industry [2]. Group 1: Industry Regulations - The initiative mandates all members of the China Vaccine Industry Association to adhere to the Vaccine Administration Law and the Price Law of the People's Republic of China, using production costs and market supply-demand as the basis for pricing [2]. - Members are required to resist disorderly low-price competition and are strictly prohibited from participating in bidding below cost, ensuring product and service quality standards [2]. - The association emphasizes innovation-driven development, urging members to focus on key technology breakthroughs and the research and application of innovative products [2]. Group 2: Market Challenges - The domestic vaccine industry has faced significant pressure in recent years due to economic downturns, declining birth rates, and reduced vaccination willingness, leading to frequent price wars among vaccine companies [3]. - In the HPV vaccine sector, a price war initiated by Watson Bio in 2022 has resulted in prices dropping below 100 yuan for the first time in 2024, with the lowest price reaching 27.5 yuan per dose [3]. - The flu vaccine market has also seen price reductions, with China National Pharmaceutical Group leading a price cut for its quadrivalent flu vaccines, forcing other manufacturers like Hualan Biologicals to engage in price competition [3]. Group 3: Financial Impact - Major vaccine companies such as Zhifei Biological Products and Watson Bio have experienced significant declines in profitability, with their stock prices also suffering substantial drops [4].
