Progress and prospect of global vaccine research and development

The emerging infectious diseases have become an important risk factor affecting human public health. Vaccination remains the most critical approach to the prevention and control of such diseases. Since the outbreak of the COVID-19 epidemic, lots of transformational basic innovative vaccine technologies and strategies have been developed. The third-generation vaccine technology represented by mRNA vaccine has gradually become a new approach to the research and development of vaccines. This paper introduces the characteristics of different vaccine technologies in recent years, and summarizes the latest research progress in current vaccine products based on different platforms, so as to provide experience and reference for future research and development of vaccines.
