Tolerability and Immunogenicity of a Single 40-µg Dose of Recombinant Botulinum Vaccine A/B (rBV A/B) for the Production of BabyBIG® in Volunteers With Existing Botulinum Immunity

California Department of Public Health·interventional·Posted Nov 2, 2023·Updated Jun 18, 2026

In Brief

A Phase 2 clinical trial evaluating rBV A/B for Botulism. Completed, enrolled 25 participants across 2 sites.

Detailed Summary

This Phase 2, open-label, uncontrolled study designed to evaluate safety, tolerability, and immunogenicity of a single dose of rBV A/B in healthy participants previously immunized with pentavalent botulinum toxoid (or pentavalent botulinum toxoid and rBV A/B) for occupational protection will be conducted to collect source plasma for potential use in the production of BabyBIG and to evaluate safety and immunogenicity of the vaccine in these participants over a 12-week period, with a follow-up safety assessment at 6 months.
