Could a 2-Visit rabies vaccine schedule offer the same protection as 3?
NCT ID NCT06066294
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This trial tests whether a two-visit rabies vaccine schedule (with two small doses on day 0 and day 7) is as safe and effective as the standard three-visit schedule (with one dose on days 0, 7, and 28) in healthy adults. The goal is to see if both schedules produce a strong immune response and to compare side effects. Participants will receive the rabies vaccine and have blood samples taken to measure antibody levels over a year.
