The race to find a new vaccine technology is crucial to help speed up and complement the World Health Organization (WHO) disease elimination program. The ultimate goal is to uncover fast and efficient production schemes in the event of a pandemic, and also to effectively fight deadly diseases such as malaria, bird flu, hepatitis, and human immunodeficiency virus (HIV). Plasmid DNA vaccines, if properly formulated, offer specific priming of the immune system and similar or even better prophylactic effects than conventional vaccines. This article discusses many of the critical issues that need to be considered when developing fast, effective, and reliable plasmid DNA vaccine manufacturing processes. Different modes of plasmid production via bacterial fermentation are compared. Plasmid purification by chromatography is specifically discussed as it is the most commercially viable bioprocess engineering technique for continuous purification of supercoiled plasmid DNA. Current techniques and progress covering the area of plasmid DNA vaccine design, formulation, and delivery are also put forward.

Each of these approaches yielded roughly similar values. The protein concentration in the granule is approx. 135-270 mg protein/ml granule volume in rat and rabbit, as compared to an average value for the protein concentration of tissue of 135 mg/g tissue for rabbits and 183 mg/g tissue for rats. This is equivalent to an average molarity for the contained proteins of between 4-9 mM based on an estimated average molecular weight for the mixture of 30 000-40 000. An upper limit for the concentration of protein in these granules can reasonably be set at about double the overall concentration of protein in the non-granule portion of the cell.
