ABSTRACT

There are many viruses in the living environment of human beings today. Once these viruses infect humans, they will begin to spread rapidly, and the cure rate of infected people is also variable, mainly depending on the patient's physical condition. At the same time, due to the incubation period of the disease, once the virus begins to spread, the consequences are very serious. From previous smallpox, polio, to modern SARS, MERS, and the new crown, the virus has brought losses to humans every time. So far, the most effective way for humans to fight the virus is to vaccinate. Since the eighteenth century, humans have invented many kinds of vaccines, including live-attenuated vaccine, inactivated vaccine, carrier vaccine, nucleic acid vaccine, and so on. At present, inactivated vaccines and attenuated vaccines are the most commonly used and most mature technologies. However, the development center in recent years has shifted to nucleic acid vaccines, especially mRNA vaccines. The mRNA vaccine itself has shown its advantages in the treatment of tumors. After the epidemic of the new coronavirus, its various advantages have allowed it to surpass traditional vaccines. This article will focus on some of the characteristics of mRNA, the working mechanism of mRNA, the characteristics of some types of mRNA, the relationship between mRNA vaccines and the new crown, and the prospects of mRNA.
