Plain-language summary
To demonstrate the immunogenicity of Sinovac rabies vaccine is non-inferior to the active-controlled rabies vaccine (Verorab®) after pre-exposure prophylaxis (PrEP) vaccination, and to confirm its satisfying safety profile in the pediatric and adult population in a PrEP schedule
