Cooperative supramolecular integration of QS-21 into polymeric micelles as a tunable nanoadjuvant platform for subunit vaccines

Key Points

The study aims to evaluate the effectiveness of QS-21 integrated into polymeric micelles as a nanoadjuvant for subunit vaccines.
Used SARS-CoV-2 Spike subunit antigen to evaluate antibody response.
Assessed systemic and mucosal antibody levels along with neutralizing activity.
Examined the cooperative supramolecular integration of QS-21 with P123.
P123/QS-21 combination resulted in enhanced systemic and mucosal antibody responses.
Increased neutralizing activity against SARS-CoV-2 observed.
Support for using supramolecular design as a strategy for improving vaccine platforms.

Abstract

evaluation using a SARS-CoV-2 Spike subunit antigen indicates that P123/QS-21 is associated with enhanced systemic and mucosal antibody responses while inducing functional neutralizing activity. Together, these findings support cooperative supramolecular integration as a biomaterials design principle to modulate membrane activity and nanoadjuvant performance, providing a scalable and tunable framework for the development of subunit vaccine platforms.
