Virus safety of biotech- and plasma-derived therapeutics is ensured through complementary manufacturing and quality control measures that include the control and monitoring of raw materials, the validation and implementation of effective virus clearance technology and the monitoring of final filled product for the presence of virus. Virus filtration, which is considered a robust and effective virus clearance technology, is a common unit operation in the manufacture of biologicals. In this article, we review the points that must be considered when selecting a virus-retentive filter. The areas covered include regulatory considerations; selecting, optimizing and validating a virus filtration step; and process scale implementation - areas that are critical to users of virus filters.

The needle and syringe have long been the standard delivery technology for vaccines. However, a confluence of market factors is driving new interest in alternative delivery systems that hold the potential to meet one or more of the following goals: improved antigen utilization, higher quality immune response, better stability and improved patient acceptance. Of particular interest are microneedle systems, otherwise referred to as microstuctured transdermal systems (MTS), that provide for targeted delivery of the vaccine formulation directly to antigen-presenting cells within the epidermis. This article provides a brief overview of MTS technology with an emphasis on solid-coated MTS for vaccine delivery.
