mRNA-based vaccines for rapid response to emerging infectious disease outbreaks

This review examines the transformative role of mRNA vaccines in responding to emerging infectious disease outbreaks, with a focus on their unique mechanisms, rapid development potential, and demonstrated efficacy. The recent success of mRNA vaccines during the COVID-19 pandemic highlights their advantages over traditional vaccines, including adaptability, scalability, and a swift response time that is essential for pandemic preparedness. Despite these benefits, mRNA vaccine technology faces notable challenges, such as stringent cold chain requirements and public acceptance issues, which could impede global distribution and uptake. This paper provides a comprehensive overview of the mechanisms and advantages of mRNA vaccines, evaluates current technical and logistical barriers, and explores potential applications for future pandemic prevention. Recommendations are presented to enhance development processes, improve vaccine stability, and foster public trust. The insights in this review underscore the promise of mRNA technology as a pivotal tool for rapid, adaptive immunization, emphasizing the need for continued research and strategic investment to fully realize its potential in safeguarding public health.
