A total of 390 healthy participants aged ≥1 years old will be enrolled. All participants will be randomized at a 2:1 ratio to receive Sinovac rabies vaccine (Trial group) or Sanofi Pasteur Verorab® (Control group), in a three doses of PrEP schedule at Day 0, Day 7 and Day 28 through intramuscular route (IM) that covers a two doses of IM PrEP schedule at Day 0, Day 7 as well.\n\nBlood samples for immunogenicity assessment will be collected at Day 0, Day 28, and Day 42. For immunogenicity assessment, the blood sample at Day 28 will be used for the two-doses IM PrEP schedule, and the blood sample at Day 42 will be used for the three-doses IM PrEP schedule, in comparison with the active-control vaccine Verorab®.\n\nFor safety assessment, the solicited local and systemic adverse events (AEs) within 7 days after each-dose vaccination (If the vaccination interval is less than 7 days, the actual interval shall prevail), as well as unsolicited AEs from the first-dose vaccination until 28 days after the last-dose vaccination will be actively monitored.
