Vaccine development research is necessary for controlling transmission, improving community immunity, and preventing further SARS-CoV-2 resurgence.
The various approaches to future vaccine development can be broadly classified into either protein subunit, plasmid DNA, mRNA, or viral vaccines. Our products and services support the development research for scalable and robust vaccines enabling large-scale cGMP production.
Vaccine-originated immunity is one of the most effective ways to protect human life, yet viruses are always evolving. Therefore, it is critical to select a vaccine approach and begin with basic lab research to identify the pathogen and antigen candidates that could cause an immune response, as well as study and understand host immune response to improve vaccine development.
We offer a broad range of products that support vaccine research, regardless of approach, enabling the speed and accuracy needed to shorten your development timeline. Learn more about our Vaccine Research and Development Tools.

The Ion Torrent Genexus system features a hands-off, setup-and-go workflow with automated reverse transcription, library prep, template prep, sequencing, and analysis all on one instrument.
The simple, fast, cost-effective Sanger sequencing workflow make it ideal at different steps of the vaccine development workflow:
- In target discovery, it is being used to identify the virus and its variants.
- Can help with optimizing the sequence of the mRNA vaccine candidate to maximize protein expression.
- Can be used to sequence and characterize the neutralizing antibodies generated as a response to the virus which could potentially have therapeutic or prophylactic utility.
The entire workflow can be completed, from sample to answer, in less than one workday. We offer products to support the entire workflow from PCR amplification to data analysis. The SeqStudio Genetic Analyzer is an affordable, low-throughput cartridge-based benchtop genetic analyzer that eliminates complex instrument set-up to deliver Sanger sequencing runs in as little as 30 mins.
The importance of human cell line authenticity
Vaccine research is often performed with cultured human cells obtained from major repositories or fellow researchers. An estimated 15–20% of the time, cells used in experiments have been misidentified or cross-contaminated with another cell line. Although major repositories now authenticate cell line identity, many are calling for all researchers to test and authenticate cell line identity using standard genotyping techniques like Short Tandem Repeat (STR) genotyping with CE.
We offer products to authenticate cell line identity:
- Applied Biosystems CLA Identifiler Plus and Direct kits are optimized to analyze 16 highly variant human STRs with amplification time of under three hours
- Applied Biosystems GeneMapper Software 6 and the cloud-based microsatellite analysis (MSA) software solutions facilitate analysis of STRs by making use of pre-established allelic ladders and sizing bin sets for the various STR alleles covered by the Identifiler kits
Flow cytometry is used to help measure the efficacy and safety of potential vaccines across their discovery and development process. Some of the advantages of flow cytometry are: ability to get data from a large number of cells from a single sample, efficiently acquire data unattended using a 96- and 384-plate autosampler, and scalability of scientific experiments as needs change. Flow cytometry is used in the screening, selection, and evaluation process of candidate vaccines where intracellular cytokine staining of CD4+ and CD8+ T cells can be used to measure their immunogenicity and efficacy. Flow cytometry immunophenotyping panels can also be used to measure changes in other cell types such as those of the innate immune response during testing. Sorting of the immune cells generated in response to candidates means they can then be further examined through NGS.
See other research tools for studying the host immune response to viral infection, or see immune monitoring immunoassays for looking at markers to assess the cytokine release storm.
Invitrogen SuperScript reverse transcriptases were developed for improved thermostability, processivity, and cDNA yields to enable performance with even the most challenging RNA samples. With over 50,000 citations, reviews, and publications, SuperScript reverse transcriptases are proven to be a superior choice for those in vaccine development.

Accelerate vaccine development using real-time PCR
Real-time PCR is an indispensable tool that is widely used throughout vaccine research and development. Real-time PCR offers an easy-to-use workflow, fast time to results, scalability for large numbers of samples, high sensitivity and specificity, and a wide dynamic range for precise detection and quantitation of nucleic acids. These unique benefits position real-time PCR as the go-to technology for a diverse range of applications, including targeted gene expression profiling of host immune responses, monitoring of virus and bioproduction cultures and stocks for adventitious agents, quantitation of virus- or gene-based vaccine dosage, assessment of viral vaccine infectivity and potency, and analytical QC of process residuals during manufacturing. Thermo Fisher Scientific offers a comprehensive portfolio of real time PCR solutions that promise to accelerate vaccine development timelines.

Spotlight Story: Vaccine development efforts at University of Queensland
Professor Paul Young and Dr. Keith Chappell at the University of Queensland are leading a group that mobilized early to develop a SARS-CoV-2 vaccine under the auspices of the Coalition for Epidemic Preparedness (CEPI). They are using a unique ‘molecular clamp’ technology together with the Gibco ExpiCHO Expression System to rapidly scale targeted vaccine development. The ExpiCHO system is uniquely suited to this project for the high yield and quality it delivers with rapid expression of vaccine development candidates. Additionally, the same cGMP-banked ExpiCHO-S cells can be used for the entire manufacturing process: from early preclinical work using transient expression, to full-scale manufacturing employing a clonally-selected, high-expression stable cell line.
Viral spike proteins reside on the surface of viruses and are used to bind to host cells, enabling viral infection. Knowledge of the precise, 3D structure of these proteins is essential for the generation of specific, effective drugs and vaccines. It also provides general insight into how the virus evades the immune system.
Researchers at the Department of Molecular Biosciences (The University of Texas at Austin) and the Vaccine Research Center (National Institutes of Health) determined the 3D structure of the SARS-CoV-2 spike protein thanks to the Thermo Scientific Krios G4 Cryo Transmission Electron Microscope (Cryo-TEM), a powerful, commercially available cryo-electron microscope for life science applications.
This structure will undoubtedly help to expedite the development and evaluation of a potential vaccine or treatment. Most notably, the structure was determined within weeks of purifying the spike protein; this quick pace heralds a potential revolution in vaccine and anti-viral development.

Process development & manufacturing
In the development of vaccines against SARS-CoV-2 virus, five different approaches are leading the way:
- Protein subunit vaccines—involve using a key part of the virus, typically the viral spike protein or part of the receptor binding domain, to develop an immune response; proteins are produced recombinantly in mammalian, microbial, or yeast cells
- mRNA vaccines—involve the injection of synthesized, packaged mRNA encoding the viral spike protein
- Viral vaccines—involve infecting cultured cells with live virus to produce whole viruses that are then killed or attenuated to be used as a vaccine
- Viral vector vaccines—involve engineering innocuous viruses with transgenes derived from a pathogen to elicit an immune response to that pathogen
