Microbix Biosystems Inc (TSX:MBX) announced today that the Company has ceased negotiations with the previously announced vaccine manufacturer currently evaluating Microbix' yield enhancement technology. The Company is seeking to commercialize a viable vaccine yield enhancement process that can be integrated into a vaccine supplier's commercial manufacturing process. Microbix believes its novel process significantly improves manufacturing yields in vaccine production.
