What is the failure rate in rabies vaccines?

According to the World Health Organization (WHO), the failure rate of rabies vaccines is extremely low. The risk of developing rabies after being vaccinated is estimated to be less than 0.1%, or 1 in 1000. However, it's important to note that the effectiveness of rabies vaccines can be influenced by several factors, including the type of vaccine used, the route of administration, the patient's immune status, and the timing of vaccination. Proper administration and adherence to the recommended vaccination schedule are crucial to ensure optimal protection against rabies.
