Journal of Vaccine Research 2024, Vol.14, No.1, 17-26 http://medscipublisher.com/index.php/jvr 24 elimination of vaccines, international organizations and public health institutions have implemented various measures. International organizations and public health institutions have strengthened cooperation in vaccine research and production. For instance, entities like the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) have increased their oversight and guidance of vaccine manufacturers to ensure vaccine quality and safety. Simultaneously, these organizations actively support vaccine research and innovation to enhance vaccine immunogenicity and safety. The global control and eradication of vaccines are vital components of the public health sector. By enhancing collaboration among international organizations and public health institutions, developing safer and more effective vaccines, promoting global vaccination initiatives, improving vaccine immunogenicity and safety, addressing vaccine storage and transportation, and monitoring and assessing vaccine immunization effectiveness and safety, China is poised to ultimately achieve global control and eradication of infectious diseases like poliomyelitis (Nathanson and Kew, 2010; Modlin et al., 2021). 4 Significance and Value of Vaccine Research and Application The significance and value of vaccine research and application are profound. Firstly, vaccines are crucial tools for preventing infectious diseases, effectively safeguarding human populations from illness. Secondly, research into and the application of vaccines not only improve public health but also promote societal and economic development. For instance, through vaccination, China can effectively control and eliminate diseases, reducing the consumption of public medical resources and the burden of societal costs. Furthermore, vaccine research and application stimulate the advancement of science and technology, driving progress in the fields of medicine and biology (Paul and Priya, 2004). Regarding the polio vaccine, research and application also hold significant meaning and value. Vaccine research and application can create economic benefits and societal welfare. Vaccination can reduce the impact of the diseases on the workforce and productivity, thereby enhancing societal productivity and economic benefits. Furthermore, vaccine research and application also can promote scientific education and raise public health awareness, increasing public understanding and importance placed on disease prevention and control. The research and application of the polio vaccine can also provide valuable lessons and references for the prevention and control of other diseases, furthering the development and progress of global public health endeavors. The significance and value of vaccine research and application are multifaceted, including disease prevention, promoting economic and social development, advancing scientific and technological progress, and enhancing public health awareness, and so on. Therefore, continued support and investment in vaccine research and application are essential, with a focus on ongoing improvements and innovations to better safeguard public health and safety. Vaccine research and application represent a long-term and critical endeavor. While China has made significant strides in vaccine research and application, there is an ongoing need for innovation and enhancement to address existing issues and challenges, ultimately providing improved protection for public health and safety in the future. From the perspective of the development history of polio vaccines, the research and application of vaccines have undergone years of effort and exploration. Since the 1950s, people have been studying polio vaccines and gradually mastering the production techniques and application methods. With the continuous advancement of technology, researchers have continuously improved and optimized the vaccine manufacturing processes and immunization strategies, leading to significant improvements in vaccine safety, immunogenicity, and coverage rates. Currently, polio vaccines have become safe and effective vaccines, widely used in polio prevention and control efforts worldwide. Through vaccination, China has successfully controlled and eliminated the majority of polio cases, providing essential protection for public health and safety (Zahra, 2022). Although significant progress has been made in the current efforts to control polio through vaccination, China still faces numerous challenges and difficulties in its future development. The sustainability and reliability of vaccines need continuous improvement. While polio vaccines have demonstrated excellent immunogenicity, there are still
