Rabies is an acute infectious disease caused by the rabies virus (RABV) that is shared by humans and animals. It is widely distributed geographically and occurs in over 150 countries and regions worldwide. Once humans and animals fall ill, almost 100% of them die, posing a huge threat to human life safety. The onset time of rabies and the site of virus invasion are related to the speed at which the virus moves to the central nervous system, usually 20-60 days or longer or shorter after infection. Rabies manifests as acute encephalomyelitis, clinically characterized by central nervous system damage such as fear of water, wind, and difficulty swallowing, followed by loss of respiratory and circulatory function and death.
At present, there is no effective treatment for rabies, and prevention is crucial, among which vaccination is the most effective prevention and control measure. The human diploid cell rabies vaccine (HDCV) has been used for over 40 years in Europe and North America, and its safety and efficacy have been fully validated. It is internationally recognized as the "gold standard" for rabies vaccines and is often used as a benchmark for newly developed vaccines. The freeze-dried human rabies vaccine (human diploid cell) involved in this study has completed phase I clinical trials, and the results show that whether administered to the 10-60 age group using the Essen procedure or the Zagreb procedure, the vaccine exhibits good safety.
