Study demonstrates 7,000+ doses of yellow fever virus 17D per egg in industry breakthrough
23rd July 2025 Mayo, Ireland: Ovagen Group Limited,an innovation-led Irish biotech, has today announced groundbreaking results from a Yellow Fever virus yield study that could transform the economics of global vaccine manufacturing.
Conducted at The Pirbright Institute (UK), a world-renowned centre tackling viral diseases of livestock, the comparative study showed that Ovagen’s Germ Free embryonated chicken eggs delivered up to 7,600 doses of yellow fever virus 17D per egg.
This yield advantage significantly lowers the cost per dose and drastically improves production efficiency with major cost saving implications combining scalability with the elimination of the use of antibiotics.
Speaking about the results of the study, Dr. Catherine Caulfield, CEO of Ovagen said:
“What we have developed isn’t incremental, it’s a complete rethink of the vaccine manufacturing process. Our germ free egg platform eliminates bacterial contamination and reduces the need for antibiotics in vaccine production, while delivering significantly higher viral yield. This is high-impact science with high-value commercial outcomes.”
The results of the Pirbright Institute study using Ovagen’s technology demonstrated that:
The technology offers immediate scalability and significant margins for manufacturers, all while reducing waste and environmental impact. For public health systems and vaccine developers alike, it enables faster response times, lower costs, and increased resilience in the face of a public health crisis.
Investor Opportunity
Ovagen’s IP-protected platform is commercially ready, with eggs already available. The company is currently engaging with strategic partners, global pharmaceutical manufacturers, and new investors to accelerate market penetration.
Backed by Enterprise Ireland, Ovagen represents a standout opportunity in Europe’s deep tech and biotech sectors. With growing global demand for scalable, clean, and efficient vaccine platforms, the company is now positioned for rapid international growth.
Tom Cusack, Head of Industrial & Life Sciences at Enterprise Ireland, said: “Enterprise Ireland is proud to support Ovagen as they continue to scale their innovation and ambition. Their germ-free egg technology shows real potential to drive greater efficiency in vaccine manufacturing, and it’s encouraging to see this level of innovation emerging from the West of Ireland. Ovagen’s progress highlights the strength of Ireland’s biotech sector and the impact that Irish companies can have on global health challenges.”
Ovagen was founded with the ambitious goal of developing the world’s first commercially viable germ-free egg production system for use in biopharmaceutical manufacturing. Having secured over €21 million in funding through a mix of private investment, promoter funds, VC, Enterprise Ireland and EIC Accelerator backing, the company has developed a state-of-the-art facility, secured global patent protection, sales traction and validated significantly higher viral yields compared to industry-standard SPF eggs.
Wayne Collins, VP of Business Development at Ovagen added:
“This is the kind of cutting edge innovation that’s built for global scale. Our commercial conversations have already begun with major pharma and vaccine manufacturers, and we’re open to conversations with strategic investors who see the scale of what’s possible here.”

Ovagen Group Limited recently attended the 11th Annual Avian Model Systems Conference at the University of Plymouth, UK (11-14SEP2023). It was a wonderful four days of fantastic avian research presentations ranging from developmental biology and evolution to immunology, novel techniques, and the application of avian models in biomedical research, diagnostics, and vaccine production. The plenary discussion and the subsequent PI meeting highlighted the strength and breadth of the avian research community, and the desire to forge a closer network with an online platform and regional resource centres.
At the global meeting, Dr. Martin Murphy presented a flash talk entitled: A novel method for the production of the world’s first avian Germ Free Eggs and a poster was prepared for exhibition at the meeting. There were three poster exhibition sessions at the meeting which was a great opportunity for Ovagen to present and discuss the unique advantages of germ free eggs in eliminating contamination in vaccine manufacture and in increasing the viral yield per egg. The diverse applications of Germ Free eggs for vaccine manufacture, oncology, CDMO’s CRO’s and research applications was highlighted. Attendance by Ovagen management at future global vaccine conferences and scientific meetings is planned for 2023/2024.
