Race Against Time: New Alliance Targets Bird Flu and Future Pandemics

October 14, 2025

Oslo and Pune – A crucial partnership between the Coalition for Epidemic Preparedness Innovations (CEPI) and the Serum Institute of india (SII) is underway, aiming to bolster global defenses against emerging infectious diseases. The collaboration centers around utilizing SII’s innovative baculovirus platform to target the H5N1 avian influenza virus,serving as a prototype for a potential “Disease X” – an unknown pathogen with pandemic potential.

The project, backed by up to $16.4 million in CEPI funding, will see SII produce and evaluate two distinct H5 antigens for use in a recombinant protein vaccine. These include a standard,or “wild-type,” antigen and an artificially intelligent (AI)-optimized,broad-spectrum antigen developed by researchers at the Houston Methodist research Institute. This broad-spectrum approach is designed to generate immune responses against multiple strains of the H5 virus, enhancing its effectiveness against unpredictable outbreaks.

Accelerating Vaccine Progress with Artificial Intelligence

Scientists believe Artificial Intelligence is a game changer in predicting and preparing for future outbreaks. The collaboration will rigorously test the baculovirus platform’s ability to swiftly manufacture new antigens in response to H5 viruses, simulating a real-world pandemic scenario. This effort will also validate the use of AI in designing vaccine antigens capable of inducing widespread, protective immunity. Antigens, crucial components of vaccines, trigger the body’s immune response.

“This project represents a notable step forward in powering up global readiness to confront pandemic threats,encompassing everything from initial vaccine development to large-scale manufacturing and distribution,” stated dr. Richard Hatchett, Chief Executive Officer of CEPI. “With a potential influenza vaccine already in development on a proven platform, and SII’s immense manufacturing capacity, we are poised to respond swiftly-possibly within 100 days-should a deadly flu virus appear.”

Baculovirus Technology: A Rapid Response Tool

baculovirus-based vaccines employ a harmless insect virus that has been genetically modified to produce a targeted antigen. This method offers a significant advantage: vaccines can be quickly created once a viral sequence is identified, making it ideal for rapid responses to emerging pandemic threats. this aligns directly with CEPI’s aspiring 100 Days Mission,a global initiative championed by G7 and G20 leaders to accelerate vaccine development to within 100 days of a pandemic’s emergence.

Adar Poonawalla, CEO of SII, added, “We are delighted to strengthen our partnership with CEPI through this vital initiative focusing on H5N1. Our validated baculovirus platform enables the rapid development and production of vaccines against emerging threats. This project will rigorously test our readiness, reinforcing our dedication to pandemic preparedness and ensuring effective vaccines reach vulnerable populations without delay.”

SII,a key vaccine supplier to over 170 countries,has a strong track record of swift responses during infectious disease outbreaks. The organization possesses ample experience with recombinant protein-based vaccine production,utilizing comparable baculovirus technology. In 2024,SII formally joined CEPI’s vaccine manufacturing network,aiming to expand pandemic response capabilities and ensure equitable access to vaccines,notably in developing nations.

The project will also draw upon the expertise of CEPI’s Preclinical Model Network and Centralized Laboratory Network, along with the UK Health Security Agency, the Medicines and Healthcare products Regulatory Agency, and the Francis Crick Institute, to conduct essential testing and ensure the vaccines are effective.

Equitable Access: A Core principle

CEPI and SII have jointly committed to ensuring equitable access to the outputs of this program,aligned with CEPI’s Equitable Access Policy. This includes prioritizing vaccine availability for at-risk populations,particularly in the Global South,at affordable prices if further vaccine development utilizing CEPI funding occurs.Project data, excluding sensitive manufacturing details, will be made openly accessible to the global scientific community.

Did You Know? The baculovirus platform offers a significantly faster production timeline compared to traditional vaccine manufacturing methods, potentially shortening the response time to emerging threats by weeks or even months.

Pro Tip: Staying informed about global health initiatives and vaccine development efforts is crucial for understanding and preparing for potential pandemic risks.

The Ongoing Threat of Pandemic Disease

The threat of pandemics remains a significant global concern. The World Health Organization (WHO) estimates that a pandemic could potentially cause trillions of dollars in economic losses and disproportionately impact vulnerable populations. Continued investment in research and development of rapid response technologies, such as the baculovirus platform, is critical for safeguarding global health security.

Recent studies indicate that the risk of novel pathogens emerging is increasing due to factors such as climate change, deforestation, and increased human-animal interaction. Proactive measures, including early detection, rapid response, and equitable vaccine distribution, are essential to mitigating the impact of future pandemics.
