For the ongoing 2014 Ebola virus outbreak, all viable options and technologies need to be evaluated as potential countermeasures to address this emerging biological threat. Novavax, Inc. has a rapid, practical vaccine development and manufacturing platform with the capability to deliver clinical trial material and, ultimately, commercial doses in response to novel infectious disease agents. This report describes the application of our platform technology for the successful generation, manufacture, and release of a clinical batch of Zaire ebolavirus glycoprotein nanoparticle vaccine three months from project initiation…

The purification of PHB-01 plantibody derived from tobacco leaves imposed difficulties when the plantibody solid-liquid extraction design was performed. Thus, our study focused on assessing a combination of an aqueous two-phase extraction (ATPE) procedure and affinity chromatography for solving some of the issues in plantibody purification. This was done using a complete factorial redesign, different polyethylene glycol (PEG)/K2PO4 proportions, and pH values in each partitioning variant.
