Mechanism and efficiency of COVID-19 vaccine and influenza vaccine

This paper mainly summarizes the comparison between the prevalent covid-19 virus and the previous influenza virus, distinguishing their advantages and disadvantages by the type of vaccine and the efficacy of booster shots. Inactivated vaccines, attenuated vaccines, and influenza vaccines all aim to boost the body's immunity against bacteria. By comparison, it is found that the covid-19 vaccine is more effective than the influenza vaccine but requires 2-3 injections and booster injections to consolidate. In addition, this article also considers the development of vaccines in the future. If the future vaccines have multiple effects in one shot, it will reduce the risk of future spread of the epidemic and the pressure on hospitals. In conclusion, the epidemic has brought many troubles to our lives. Vaccines, as the result of scientific and technological development, can eliminate most of the threats, but the virus will also mutate the corresponding vaccines. Therefore, for future consideration, developing a more efficient vaccine with fewer side effects to fight the virus is a guarantee for human safety.
