Brief Summary
The Phase 3 clinical trial of freeze-dried human rabies vaccine (human diploid cells) adopted a randomized, blinded, parallel control,non-inferiority design,and administered vaccines to participants aged 10 to 60 years with different immunization schedules (5-dose schedule group, two simple 4-dose schedule groups, and 2-1-1 schedule group) to evaluate the immunogenicity and safety of the vaccine.
