Griffith University researchers have achieved a significant breakthrough in vaccine development, potentially revolutionizing the field. This breakthrough involves the creation of a novel vaccine modality, currently in its proof-of-concept phase. Spearheaded by Professor Bernd Rehm and Dr. Shuxiong Chen, this pioneering technology involves the reprogramming of Escherichia coli cells to produce abundant vaccine particles. Notably, these vaccine particles exhibit remarkable stability at room temperature, which is particularly advantageous for regions with limited access to refrigeration, such as developing countries.
The researchers at Griffith University are on the verge of a transformative advancement in vaccine development, thanks to their innovative vaccine modality.
Professor Bernd Rehm and Dr. Shuxiong Chen, affiliated with Griffith Institute for Drug Discovery (GRIDD) and Griffith’s Centre for Cell Factories and Biopolymers, have successfully devised a stable particulate vaccine as part of their groundbreaking work.
Development and Testing
It’s important to note that this new vaccine modality is currently in the proof-of-concept phase and early stages of development. To demonstrate its efficacy, it was tested alongside an established Griffith vaccine designed to combat Strep A, a bacterium responsible for various human infections. Remarkably, the Griffith Strep A vaccine is currently demonstrating strong performance in human clinical trials in Canada.
Professor Rehm emphasized the positive outcomes of their tests, highlighting that this technology facilitates the creation of vaccines that are not only safe but also induce robust immune responses against Strep A.
“The synthetic vaccine relies on our innovative technology, which involves the reprogramming of harmless Escherichia coli cells to produce biopolymer particles coated with Griffith Strep A antigens. These particles have proven to be safe and effective against infections. Furthermore, we’ve devised a cost-effective manufacturing process, and the resulting vaccines exhibit stability at ambient temperatures, greatly simplifying storage and distribution, particularly in regions lacking refrigeration facilities, often seen in developing countries.”
Future Prospects and Next Steps
Dr. Chen underscored the potential significance of this advancement, noting its potential applicability to a wide range of vaccine development efforts.
“Our immediate next steps involve the production of high-quality vaccines and their evaluation through clinical trials,” Dr. Chen explained.
The Global Threat of Strep A
Group A Streptococcus, commonly known as Strep A, represents a global human pathogen responsible for a spectrum of infections, ranging from mild pharyngitis and impetigo to severe conditions like toxic shock syndrome, necrotizing fasciitis, and cellulitis. Importantly, Strep A-related mortality is exacerbated by the development of antimicrobial resistance, driven by the widespread use of antibiotics.
Globally, Strep A leads to a staggering 700 million human infections each year, resulting in over 500,000 deaths.
Professor Bernd Rehm and his team collaborated with Professor Michael Good from Griffith’s Institute for Glycomics, whose team provided expertise in testing this technology using a Strep A infection model.
Professor Good’s team has also developed a Strep A vaccine, currently undergoing human clinical trials in Canada.

This ain’t crypto, but it’s still groundbreaking! Hope these vax help folks in places without fridges.
Griffith Uni’s got some genius minds cookin’ up new vax! reprogrammin’ coli cells, keepin’ vax stable at room temp, that’s cool stuff!
Econ can benefit from this tech too! Imagine the cost savings if it works out.
Not cars, but fascinating! Science is amazing, ain’t it?
Strep A’s a big prob, glad they’re makin’ progress. Hope clinical trials go well!
