View all research conducted at the Vaccine Research Center (VRC)
The Vaccine Production Program (VPP) applies cutting-edge science and engineering approaches to plasmid design, cell expression, purification, formulation, and analytics. The multidisciplinary nature of the work requires expertise in a number of scientific fields, including molecular and cellular biology, biochemistry, biophysics, biomedical and chemical engineering, and traditional pharmaceutics. The broad portfolio of knowledge, coupled with a strong culture of collaboration and innovation, makes the VPP one of the most versatile product development organizations in infectious disease research. Notable achievements include the development of novel quadrivalent and hexavalent mosaic nanoparticle vaccines to fight influenza, as well as breakthroughs in production and stabilization of trimeric protein vaccine candidates for human immunodeficiency virus (HIV) and respiratory syncytial virus (RSV).
The Vaccine Production Program portfolio includes a diverse array of both traditional and novel vaccine technologies and biologics, including:
- Protein Subunits
- Peptide-Carrier Protein Conjugates
- Enveloped and Non-Enveloped Virus-Like Particles
- Protein Nanoparticles
- Mosaic Multi-Component Nanoparticles
- Monoclonal Antibodies
- Multi-specific Antibodies
- mRNA-Lipid Nanoparticles

VPP Research and Technology
The Vaccine Production Program (VPP) is a science-driven organization that exists as a unique bridge between government and the biopharmaceutical industry. Research at the VPP combines the rigor of academic research with cutting-edge development. Specialized teams of scientists and engineers work in close collaboration with each other, other labs and programs within the VRC and the NIH, as well as with academic and industry partners.
Cell Line Development Group
The Cell Line Development group is responsible for generating cell lines that produce high and consistent levels of a target vaccine or therapeutic protein. This includes expression vector construction, transfection of the production host cell line, and generation of stable cell pools, followed by single-cell isolation, scale-up, and evaluation for most vaccine products. The final cell bank is ultimately used to support current good manufacturing practice (cGMP) manufacturing of the clinical trial material.
Upstream Process Development Group
Research in Upstream Process Development centers on the identification and optimization of process parameters to support and control the growth of a mammalian or microbial cell line in a production bioreactor. The resulting process must ensure a robust and scalable method to deliver high-yielding expression of the recombinant vaccine or other protein of interest. Development begins with automated microbioreactors (15 to 250 mL) and progressively increases from 3 L bench-scale bioreactors up to a pilot scale of 50 L. The finalized processes are then transferred externally to enable larger scale manufacturing of clinical material under cGMP regulations.
Downstream Process Development Group
Downstream Process Development employs diverse purification techniques to produce high-quality recombinant products from mammalian or microbial culture harvests. The unit operations include bulk filtration (removal of cells, cell debris, or other particulate matter), specialized chromatography steps (to separate soluble impurities like host cell proteins and DNA), and specialized filtration and/or buffer exchange steps. Ultimately, the process is transferred externally for cGMP execution at scales supporting up to 2000 L cell culture harvests. At this manufacturing scale, a high-yielding process is capable of delivering up to kilogram yields of clinical product.
Analytical Development Group
The goal of analytical method development is to design and qualify analytical methods in areas such as specific binding activity, physicochemical attributes, impurity levels, etc. These methods are applied to the characterization and evaluation of product quality, defined by its biological activity (potency), identity, purity, and stability. The Analytical Development group is also responsible for transfer of these methods to the Quality Control laboratory of a cGMP manufacturing site.
Formulation Development Group
The Formulation Development group is responsible for developing formulations that ensure the quality of the vaccine candidates through cGMP manufacturing and clinical trials. Factors such as physical stress, temperature, light, and atmospheric oxygen can affect the physical and chemical stability of the vaccine. The Formulation Development group utilizes high-throughput methods focusing on molecular conformational, colloidal, and thermodynamic properties to identify optimal stabilizing solution conditions and additives.
Scientific Operations Group
Scientific Operations facilitates the scientific mission of the VPP through the management of essential support systems that ensure efficient day-to-day operations. These systems include procurement, management of critical reagents and materials, safety, document retention, shipping/receiving, and coordination with NIH/NIAID groups and collaborators, including clinical sites worldwide.
