Bioprocessing in Vaccine Development and Manufacturing

Solutions for vaccine process development through production

The development of new vaccines is challenging and requires profound knowledge of processes and high-quality equipment. New bioprocess technologies such as single-use equipment and process automation open up novel possibilities for quality control and validation. This is especially important in GMP regulated environments such as in the development and manufacturing of new vaccines. The COVID-19 pandemic starting in 2020 underlined the strong need for the efficient development of new processes. The fast and reliable tech transfer of these processes to scale up to clinical production volumes is key for the efficient development of new vaccinations.

Introduction to vaccines and vaccine development

At the beginning of a new vaccine there is the decision about the vaccine type and the selection of the antigen. In vitro and in vivo studies precede the development of a manufacturing process. Get to know more about vaccines and their development.

Challenges in upstream bioprocess development forviral vector production

Viral vectors are used in molecular biology research, gene therapy applications, and in vaccine development. High yield, scalability, robustness and commercial viability are some of the demands bioprocess engineers impose on bioprocesses for viral vector production. Cell & Gene Therapy Insights has talked with our colleagues Ankita Desai and Dr. Philipp Nold, bioprocess field application specialists, about the challenges they see in upstream bioprocess development for viral vector production.

Development of a Scale-Down Model for rAAV Viral Vector Production Using a Sf9/BEV System

Researchers at Généthon® developed a scale-down model for rAAV viral vector production in a Sf9/BEV system using a DASbox Mini Bioreactor System. They reproduced cell growth and production performance. The DASbox system allowed the comparison of different experimental conditions in parallel runs, which accelerated scale-down model development.

rAAV Production in Suspension CAP GT® Cells in BioBLU® 3c and 10c Single-Use Vessels

Researchers at Cevec Pharmaceuticals adapted the small scale shake flasks rAAV production process to stirred-tank bioreactors and scaled it up from a working volume of 2 L to 10 L, using BioBLU Single-Use Vessels. It led to comparable cell growth and virus production at both scales and to the original shake flask process.

Transient Lentiviral Vector Production in HEK 293T Cells Using the BioFlo® 320 Control Station with a BioBLU® 5p Single-Use Packed-Bed Vessel

Lentiviral vectors (LVs), which are especially applicable to gene therapy, are promising vector types for the clinical trials of such treatments. This application note describes the first successful experimental setup to cultivate LVs in HEK 293T cells adherently grown on Fibra-Cel® disks in a BioBLU 5p Single-Use Vessel.

Perfusion

Continuous cultivation techniques and perfusion have the potential to increase the efficiency of biopharmaceutical manufacturing processes. They can help increasing product titers while decreasing production volumes needed.

Single-use technology

Single-use bioreactors are routinely used in biopharmaceutical R&D and biologics manufacturing. They have the potential to reduce turn-around times and the risk for contaminations and make validations easier. One potential problem of single-use systems, however, is the release of chemical compounds into the culture medium. Standardized tests help investigating the effects of leachables and extractables (L&Es) on cell growth.

Microbial vaccine development

Recent surveys see an increasing demand of microbial expression systems in the biopharmaceutical industry. Their advantages are obvious: Bacterial hosts are easy to cultivate, grow fast, and media are less expensive than complex cell culture media. A growing range of single-use fermentors has the potential to diminish labor costs, shorten turn-around times, and make validation easier.
