Strategic and Technical Considerations in Manufacturing Viral Vector Vaccines for the Biomedical Advanced Research and Development Authority Threats.

Over the past few decades, the world has seen a considerable uptick in the number of new and emerging infectious disease outbreaks. The development of new vaccines, vaccine technologies, and platforms are critical to enhance our preparedness for biological threats and prevent future pandemics. Viral vectors can be an important tool in the repertoire of technologies available to develop effective vaccines against new and emerging infectious diseases.

Ultraviolet dosage and decontamination efficacy were widely variable across 14 UV devices after testing a dried enveloped ribonucleic acid virus surrogate for SARS-CoV-2.

The dosages and efficacy of 14 ultraviolet (UV) decontamination technologies were measured against a SARS-CoV-2 surrogate virus that was dried onto different materials for laboratory and field testing. A live enveloped, ribonucleic acid (RNA) virus surrogate for SARS-CoV-2 was dried on stainless steel 304 (SS304), Navy Top Coat-painted SS304 (NTC), cardboard, polyurethane, polymethyl methacrylate (PMMA), and acrylonitrile butadiene styrene (ABS) materials at > 8.0 log plaque-forming units (PFU) per test coupon.

Hot, Humid Air Decontamination of Aircraft Confirmed That High Temperature and High Humidity Are Critical for Inactivation of Infectious, Enveloped Ribonucleic Acid (RNA) Virus.

To develop infectious (live/dead) enveloped virus test indicators and response surface methodology (RSM) models that evaluate survival of an enveloped ribonucleic acid (RNA) virus on contaminated aircraft materials after exposure to hot, humid air (HHA). Enveloped RNA bacteriophage Phi6 (Φ6) was dried on wiring insulation, aircraft performance coating (APC), polypropylene, and nylon at ≥ 8 log plaque-forming units (PFU) test coupon. Only 2.
