The drug name for the rabies vaccine is Human Rabies Vaccine, which usually has no effect on the physical development of children. The human rabies vaccine is primarily used for active immunization against rabies and is available for both pre-exposure and post-exposure immunization. Pre-exposure immunization is vaccination before the possibility of rabies infection, especially veterinarians, breeders, slaughterhouse workers, hunters, and rabies research laboratory personnel. Post-exposure immunization is immunization after exposure to an animal suspected of having rabies, having rabies, or a carcass that has been previously vaccinated against rabies. Adverse reactions to human rabies vaccine include hard painful redness at the injection site, fatigue, fever, headache, myalgia, and gastrointestinal disturbances, which usually do not affect the physical development of children. It is recommended that children who become unwell after rabies vaccination should go to regular hospitals in time to avoid delays.
