Immunogenicity and Safety of a Purified Vero Rabies Vaccine-Serum Free, Compared With 2 Licensed Vaccines, in a Simulated Rabies Post-Exposure Regimen in Healthy Adults in France: A Randomized, Controlled, Phase 3 Trial.

ABSTRACT:

Background

A next-generation Vero cell rabies vaccine (PVRV-NG2) was developed using the same Pitman-Moore strain as in the licensed purified Vero cell vaccine (PVRV; Verorab) and the human diploid cell vaccine (HDCV; Imovax Rabies®).

Methods

This dual-center, modified, double-blind, phase 3 study evaluated the immunogenic non-inferiority and safety of PVRV-NG2 with and without concomitant intramuscular human rabies immunoglobulin (HRIG) versus PVRV + HRIG and HDCV + HRIG in a simulated post-exposure prophylaxis (PEP) regimen. Healthy adults ≥18 years old (N = 640) were randomized 3:1:1:1 to PVRV-NG2 + HRIG, PVRV + HRIG, HDCV + HRIG, or PVRV-NG2 alone (administered as single vaccine injections on days [D] 0, D3, D7, D14, and 28, with HRIG on D0 in applicable groups).
