ROI Calculation Logic

Traditional influenza vaccine manufacturing requires extensive culture time and media costs for virus proliferation. By adopting this technology, a 1.5x improvement in virus proliferation efficiency could reduce the required operating time for culture facilities by approximately 30% for an annual production of 200 million doses (an example of domestic market scale). This is estimated to result in an annual reduction of ~$6.5M (AI est.) in culture-related costs (labor, electricity, media, etc.), assuming a 20% reduction from an annual total production cost of ~$350M (AI est.).

Speed to Market
4× faster than in-house development
This technology is based on a clear mechanism of specific gene expression suppression, establishing a technical foundation for improving influenza virus production efficiency. Utilizing widely used HEK293, Vero, and MDCK cells significantly shortens the several years required for de novo cell line development and optimization. Licensees could focus on validating the technology's application to existing cell culture facilities and protocols, potentially reducing time-to-market to approximately 1.0 year, a lead time reduction of about 3.0 years compared to in-house development.
