Core Viewpoint - The article discusses the evolution of the HPV vaccine market in China, highlighting the challenges and changes in demand, pricing, and competition among vaccine manufacturers, particularly focusing on Merck's HPV vaccines and the emergence of domestic competitors [1][2][3]. Group 1: HPV Vaccine Market Dynamics - The HPV vaccine market in China has seen significant fluctuations, with Merck's four-valent and nine-valent vaccines initially experiencing high demand but later facing a decline in sales due to market saturation and competition from domestic vaccines [7][8][30]. - The introduction of domestic two-valent HPV vaccines at lower prices has intensified competition, leading to a price war that has drastically reduced the cost of HPV vaccines in China, with prices dropping below 200 yuan per dose [26][29]. - By August 2024, the price of the two-valent HPV vaccine had plummeted to 27.5 yuan per dose, reflecting the aggressive pricing strategies adopted by domestic manufacturers [29]. Group 2: Impact on Merck and Domestic Competitors - Merck's nine-valent HPV vaccine maintained a stable price due to its unique market position, but the increasing affordability of domestic vaccines has eroded its market share, particularly among cost-sensitive consumers [16][30]. - Despite Merck's strong sales growth in the past, with a 136.16% year-on-year increase in the number of nine-valent vaccines sold in 2023, the company faces challenges as the overall market for HPV vaccines in China is experiencing a decline in total issuance [30][33]. - Domestic manufacturers like Wantai and Watson have entered the market, leading to a significant shift in the competitive landscape, with both companies struggling to maintain profitability amid falling prices [29][36].
