Research on the advantages and disadvantages and the challenges of mRNA vaccines: taking the COVID-19 mRNA vaccine as an example

Abstract

Since the outbreak of the COVID-19 pandemic in 2020, the medical system of many countries has been gradually defeated. COVID-19 The virus exists all the time and everywhere. There is a "new normalcy" that the novel coronavirus coexistence with human beings in many countries. For example, the smallpox virus, which once killed hundreds of millions of people in history, was eradicated globally by vaccination in the 1970s COVID-19. Among the many COVID-19 vaccines currently used, including inactivated vaccines and adenovirus vector vaccines, mRNA vaccines - a relatively new vaccine category, are widely used and accompanied by a lot of controversy. This article will start with COVID-19, the history of vaccines, the basic introduction of mRNA, and gradually uncover the mystery of mRNA vaccines. This paper introduces its advantages and disadvantages, expounds the main development directions of mRNA vaccines, and reveals that mRNA has great development space and opportunities. This technology has many advantages. Through more in-depth research experiments, it can be applied to more medical technologies to help humans overcome diseases.
