Valneva and Serum Institute of India End Chikungunya Vaccine License Agreement
On December 31, 2025, Valneva SE, a specialty vaccine company, and the Serum Institute of India (SII), a leader in global vaccine manufacturing, announced the mutual discontinuation of their license agreement for Valneva's single-shot chikungunya vaccine. This decision enables Valneva to regain full rights over the vaccine, aiming to enhance supply chain control and commercialization efforts in high-risk countries.
Strategic Focus on High-Risk Regions
Valneva's strategic intent behind this agreement is to accelerate access to the chikungunya vaccine in endemic regions, primarily focusing on low-and-middle-income countries (LMICs). This initiative aligns with Valneva's funding agreement with the Coalition for Epidemic Preparedness Innovations (CEPI), established in July 2024, which is supported by co-funding from the European Union.
Understanding Chikungunya Virus (CHIKV)
The chikungunya virus is a mosquito-borne illness transmitted by Aedes mosquitoes. Symptoms include severe joint and muscle pain, fever, headaches, fatigue, and rashes, with joint pain potentially lasting for years. Since its resurgence in 2004, CHIKV has affected over 110 countries across Asia, Africa, Europe, and the Americas, with more than 3.7 million cases reported in the Americas from 2013 to 2023. The World Health Organization recognizes chikungunya as a major public health challenge, particularly as climate change continues to expand the geographic range of its mosquito vectors.
