Developing a SARS-CoV-2 vaccine presents numerous and unprecedented challenges; prominent among them are greatly accelerated timelines. Ordinarily for a new drug product, there is sufficient time for selection/evaluation of the vial/stopper packaging system – one that guarantees quality and safety from manufacture through delivery. This is not the case for a SARS-CoV-2 vaccine where the primary packaging system must be chosen quickly, creating a higher risk.
