Research and Development of Medical Countermeasures for Emerging Infectious Diseases, China, 1990-2022.

Since the severe acute respiratory syndrome outbreak in 2003, China has invested substantial efforts in promoting scientific and technological advances for medical countermeasures against high-threat pathogens. The examination of China's landscape identifies progress and gaps in research and development (R&D) and also highlights management and regulatory issues that should be of concern to other countries. Our study examined the current state of R&D of medical countermeasures in China during 1990-2022. The findings showed a robust and diversified pipeline responding quickly to disease outbreaks and policy changes. However, proactive and highly innovative candidates are limited, and a large proportion of vaccines and drugs stagnate at the early development stage. A paradigm shift involving a preemptive R&D agenda and persistent investment, innovative technology development, and accelerated research translation is urgently needed to prepare for the next pandemic.
