Experimental Group: SYN023+Rabies Vaccine
1000 patients aged 18 and above with World Health Organization (WHO) Category III rabies exposure should be enrolled as planned and randomly assigned to the experimental group and the control group based on a ratio of 3:1 through on-site stratification as part of post-exposure prophylaxis (PEP). SYN023: 0.3 mg/kg, wound infiltration injection. If the study drug isn't used up after infiltration injection for all wounds, the remaining amount should be injected into the muscles far away from the vaccine injection sites Frequency/duration: at Day 1 Rabies Vaccine: 0.5 milliliters (mL), intramuscular injection into the deltoid muscle Frequency/duration: at Day 1, 4, 8, 15, 29
Control Group: Human Rabies Immune Globulin (HRIG)+Rabie Vaccine

PRIMARY outcome

Timeframe: Day 8

Population: The primary analysis set of the outcome measure data is Per-Protocol Analysis Set (PPS). The PPS included all subjects who were randomized, received the correct study drug, passed the confirmation of the inclusion/exclusion criteria \*, completed the rabies vaccination schedule as required by the protocol on Day 29 of the study, had no major protocol violations impacting efficacy evaluation, received adequate wound treatment of all exposed sites, and received study drug injection.

Rabies Virus Neutralizing Activity (RVNA) was assessed using Rapid Fluorescent Focus Inhibition Test (RFFIT).

WHO's Classification of Rabies Cases: 1. Suspected case: refers to a case that satisfies the definition of clinical case; 2. Probable case: refers to a suspected case with a reliable medical history of contact with any suspected animal infected with the rabies virus; 3. Confirmed case: refers to a suspected or probable case that is proved to be infected based on the lab test result.

Measure
Experimental Group: SYN023+Rabies Vaccine
n=750 participants at risk
1000 patients aged 18 and above with WHO Category III rabies exposure should be enrolled as planned and randomly assigned to the experimental group and the control group based on a ratio of 3:1 through on-site stratification as part of PEP. SYN023: 0.3 mg/kg, wound infiltration injection. If the study drug isn't used up after infiltration injection for all wounds, the remaining amount should be injected into the muscles far away from the vaccine injection sites Frequency/duration: at Day 1 Rabies Vaccine: 0.5 mL, intramuscular injection into the deltoid muscle Frequency/duration: at Day 1, 4, 8, 15, 29
Control Group: HRIG+Rabie Vaccine
n=250 participants at risk
1000 patients aged 18 and above with WHO Category III rabies exposure should be enrolled as planned and randomly assigned to the experimental group and the control group based on a ratio of 3:1 through on-site stratification as part of PEP. HRIG: 20 IU/kg, wound infiltration injection. If the study drug isn't used up after infiltration injection for all wounds, the remaining amount should be injected into the muscles far away from the vaccine injection sites Frequency/duration: at Day 1 Rabies Vaccine: 0.5 mL, intramuscular injection into the deltoid muscle Frequency/duration: at Day 1, 4, 8, 15, 29
