Preparation of a Nanoemulsion Adjuvant Vaccine

Executive Industry Relevance

Nanoemulsion-based vaccine formulations offer a scalable approach to adjuvant delivery, enhancing antigen presentation and immune activation. This method supports early-stage vaccine development by enabling stable, reproducible formulations for preclinical evaluation. The use of MPLA and squalene as adjuvants provides a mechanistic foundation for de-risking immunomodulatory strategies in oncology and infectious disease pipelines.
