Significant research is being done to develop and improve delivery mechanisms for biopharmaceuticals and vaccines, including pulmonary (inhalation), nasal, transdermal, and oral alternatives. Market projections indicate that the delivery of proteins and vaccines by inhalation and oral formulation has become and will continue to be increasingly important. These delivery mechanisms, to be effective, will require better stabilization of the biologicals so that they can maintain potency and effectiveness at ambient temperatures for extended periods of time. The novel Preservation by Vaporization (PBV) Technology described herein provides cost-effective and efficient industrial scale stabilization of proteins, viruses, bacteria, and other sensitive biologicals, thereby allowing a production of products that are not possible to be produced by existing methods. The suggested new PBV process comprises primary drying under vacuum from a partially frozen state (i.e. slush) at near subzero temperatures followed by stability drying at elevated temperatures (i.e., above 40 degrees Celsius). The new suggested method can be performed aseptically in unit doze format (in vials) and/or in bulk format (in trays, bags, or other containers). The drying can be performed as a continuous load process in a manifold vacuum dryer comprising a plurality (e.g., 30) of vacuum chambers attached to a condenser during the drying.

The present invention is directed to the development of continuous processing technology for the purification of biopharmaceuticals and biological products, such as monoclonal antibodies, protein therapeutics, and vaccines. Methods for continuous processing of a biological product in a feed stream toward formulation of a purified bulk product are described.

Disclosed is a process of determining, at a point during shipment, whether the solid phase refrigerant in a shipment is sufficient to preserve the shipment cargo, which is blood or other biological products, for the remaining shipment period, by: monitoring the temperatures encountered to said point and estimating the temperatures likely to be encountered during the remaining shipment period; determining the likelihood that the remaining refrigerant can maintain the shipment cargo within a specified temperature range during the remaining shipment period; and if the risk that the remaining refrigerant cannot maintain the shipment cargo within said range during the remaining shipment period is above a cut-off level, then taking action to preserve the value of the cargo.

A freeze-dried high-temp. resistant protecting agent for virus-type biologic products for veterinary medicine is prepared from several components through proportionally mixing. It features that each of its components is sterilized separately. For the components which can be sterilized under high temp., they are dissolved in distilled water according to the proportion of formulation and are sterilized at 116 deg.C for 30-40 min; and for those which do not resist the high temp., they are also dissolved in distilled water according the proportion of formulation and are filtered with 0.22 micron pore diameter filter membrane to remove bacteria; and then the two parts are mixed to obtain the freeze-dried high-temp. resistant, protecting agent. The mentioned two parts are added to the virus antigen liquid according to a proportion of 1:1 and after packaging, they are freeze-dried. The product can be stored at 2-8 deg.C for 24 months.
