广东基孔肯雅热病例数累计逾七千例,缘何药企研发疫苗积极性不高
第一财经· 2025-08-14 10:00
Core Viewpoint - The article discusses the current situation of Chikungunya virus cases in Guangdong, highlighting the lack of vaccine development and the challenges faced by domestic vaccine companies in China [3][4]. Summary by Sections Current Situation - As of August 9, 2025, Guangdong province has reported over 7,000 local cases of Chikungunya fever, with some cases reported in other regions outside Guangdong [3]. Disease Overview - Chikungunya fever is an acute infectious disease caused by the Chikungunya virus, transmitted by Aedes mosquitoes, characterized by fever, joint pain, and rash. There is currently no specific treatment or vaccine available in China [3]. Vaccine Development Challenges - Domestic vaccine companies show low enthusiasm for developing a Chikungunya vaccine due to factors such as market potential, development success rates, costs, competitive landscape, and profit margins. The estimated costs for vaccine development phases range from 30 million to several hundred million yuan [4][5]. - The economic value of developing a Chikungunya vaccine is considered limited due to the disease's transmission being primarily through mosquito vectors concentrated in tropical and subtropical regions, making nationwide spread unlikely [5]. Market Considerations - The current model of "imported cases leading to local transmission" results in annual incidence numbers far lower than common infectious diseases like influenza and hepatitis B, leading companies to prioritize vaccines with higher return on investment [5]. - The traditional vaccine development process could take five to seven years, during which time the market may be dominated by imported vaccines, creating uncertainty for domestic developers [5]. Prevention Measures - Preventive measures against Chikungunya primarily focus on mosquito control, including eliminating breeding sites and using repellents and mosquito nets [6].
