Research and Technological Optimization of Polio Vaccines

Poliomyelitis, caused by various enteroviruses, is an acute infectious disease that primarily affects children, especially in Asia and Africa. It is mainly transmitted through the fecal-oral route, leading to severe neurological complications such as paralysis and respiratory failure. Over the past few decades, significant progress has been made in the control and reduction of poliomyelitis through vaccination programs and global initiatives. The importance of polio vaccines lies in their ability to prevent and control the occurrence and spread of poliomyelitis. Since the introduction of the first polio vaccine in 1963, vaccination has become one of the fundamental strategies for controlling and eradicating the disease. Through vaccination, individuals can achieve long-term immunity, reducing the incidence and mortality rate of poliomyelitis. This review provides a comprehensive overview and analysis of the development and current status of polio vaccines, summarizing the classification, characteristics, research progress, and future directions of these vaccines. It also discusses the significance and value of vaccine research and application, aiming to elucidate the latest achievements and advancements in current vaccine research, provide valuable information and references, and promote progress and application in polio vaccine research.
