Over the period from 2020 to 2023, a four-year non-military battle drew to a close, marking the end of the COVID-19 pandemic that will be etched into history. During this time frame, policies and technologies aimed at combating the virus were developed, ultimately saving numerous lives and enhancing people's efficacy in battling the virus while demonstrating unwavering determination. However, some less mature biological nucleic acid technologies and some controversial policy bases are still being improved. Through the development of biotechnology levels and policies, the research and development of three mRNA vaccines, health codes and RT-PCR nucleic acid detection methods have greatly improved the efficiency of epidemic prevention and control. The government's policy of controlling speech and behavior at the initial stage of the outbreak brought people together to fight against the virus. These technologies are being researched to reduce the number of casualties and minimize losses. For example, circRNA or saRNA vaccines are still in the research stage. If these more advanced techniques are put into use, it will undoubtedly greatly increase the means of fighting against the virus. This is also the direction and key for future research and development.
