Comparing two rabies vaccination schedules for safety and immune response

A Randomized Controlled Trial on Safety and Immunogenicity of Purified Verocell Rabies Vaccine as Pre-exposure Prophylaxis Via Intradermal Two Visits (2-0-2-0-0) Verses Three Visits (1-0-1-0-1) Regimen on Healthy Volunteers

Phase 3 Interventional Kempegowda Institute of Medical Sciences, Bangalore · NCT06066294

This study is testing two different rabies vaccination schedules to see which one is safer and helps people build better immunity against the virus.

What this trial studies

This clinical trial aims to compare the safety and immunogenicity of two rabies pre-exposure prophylaxis (PrEP) regimens: one recommended by the Government of India and the other by the World Health Organization (WHO). Healthy adult volunteers will be randomized into two groups, receiving either the WHO-approved schedule or the Indian government schedule. The study will assess seroconversion rates and the incidence of adverse events following vaccination. Participants will be monitored for safety after each dose and followed up for a year to evaluate long-term immune response.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy adults over 18 years who are willing to participate and provide informed consent.

Not a fit: Patients who have previously received rabies vaccination or are severely immunocompromised, pregnant, or lactating may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could optimize rabies vaccination protocols, potentially improving protection against rabies for individuals at risk.

How similar studies have performed: While there have been studies on rabies vaccination, this specific comparison of the two regimens is novel and has not been extensively tested.
