Safety and Immunogenicity of Purified Verocell Rabies Vaccine PVRV Administered Intramuscularly and Intradermally

Rabies Clinical Trial

Official title:
An Open-label, Randomized Study Evaluating the Safety and Immunogenicity of the Purified Vero Cell Rabies Vaccine PVRV Administered Intradermally and Intramuscularly as Post-exposure Prophylaxis

Clinical Trial Summary

Rabies is fatal disease but preventable with rabies vaccines and immunoglobulins, conventionally involves intramuscular (IM) administration of the vaccine. However, switching the intradermal (ID) route offers potential advantages in dosing, time and cost without compromising efficacy and safety. Therefore, this study aims to compare the safety and immunogenicity of a short-term three-doses intradermal regimen (3D-ID) with a conventional five-doses intramuscular regimen (5D-IM) of the purified Vero cell rabies vaccine (PVRV), administered via both intramuscular (IM) and intradermal (ID) routes as post-exposure prophylaxis (PEP).

Clinical Trial Description

Rabies vaccines can be used ID for PEP, according to a WHO Expert Committee recommendation. The administration of short-term PEP through ID (3-doses) offers a safe, immunogenic, dose-sparing, and cost-effective alternative to the conventional protocol (IM, 5-dose regimen) while reducing the volume by up to 60 to 80% and vaccination schedules by 3 weeks. This strategy has the potential to reduce the overall requirement and cost of such vaccines, along with minimizing the burden on healthcare professionals and facilities. Furthermore, this strategy is more likely to improve vaccination compliance compared to conventional protocol, and will certainly improve treatment outcomes. ;
