Core Viewpoint - The spread of Chikungunya fever in Guangdong has exceeded 7,000 local cases, with limited vaccine development interest from domestic companies due to market uncertainties and high costs associated with vaccine research and development [1][2]. Group 1: Disease Overview - Chikungunya fever is an acute infectious disease caused by the Chikungunya virus, primarily transmitted by Aedes mosquitoes, characterized by fever, joint pain, and rash [1]. - There is currently no specific treatment for Chikungunya fever, and no vaccines are available for use in China [1]. Group 2: Vaccine Development Challenges - Domestic vaccine companies show low enthusiasm for developing a Chikungunya vaccine due to limited market potential, high research and development costs, and the risk of low sales post-development [2]. - The estimated costs for vaccine development phases are approximately 30 million yuan for preclinical and phase I trials, 30 million yuan for phase II, and 50 to 80 million yuan for phase III, with total costs potentially reaching several hundred million yuan depending on disease prevalence [1][2]. Group 3: Market Dynamics - The Chikungunya virus has only one serotype, and while technical routes for vaccine development are feasible, the economic value of developing such a vaccine is considered limited due to the low incidence of cases compared to other common infectious diseases [2]. - Companies are more likely to invest in vaccines with higher return on investment, and significant investment in Chikungunya vaccine development may only occur if there is a clear national strategic reserve demand or limitations on imported vaccines [2]. Group 4: Prevention Measures - Preventive measures against Chikungunya fever focus on mosquito control, including eliminating breeding sites and using repellents, incense, and mosquito nets [3].
