Rabies
Conditions
Brief summary
The purpose of this single-centre, randomized, double-blind, parallel control, phase 3 study is to evaluate the safety and immunogenicity of a rabies vaccine (Vero Cell) for human use in healthy Chinese subjects aged 10-60 years, according to the Essen methods (1-1-1-1-1) vaccination.
Detailed description
There will be two immunization arms. 1200 healthy subjects will be randomly assigned (1:1) to receive an experimental vaccine or a parallel comparator vaccine. All of them will be received five doses of rabies vaccine at day 0,3,7,14,28 according to the traditional Essen methods (1-1-1-1-1) vaccination.
Interventions
A rabies vaccine (Vero Cell) for human use produced by Changchun Werersai Biotech Pharmaceutical Co., Ltd. 1.0 ml experimental vaccine on day 0,3,7,14,28
A rabies vaccine (Vero Cell) for human use produced by Jilin Maifeng Biotech Pharmaceutical Co., Ltd. 1.0 ml comparator vaccine on day 0,3,7,14,28
