This paper explores the application of CoPoP liposome-based nanotechnology, particularly focusing on the incorporation of saponins like QS-21 as adjuvants, to enhance vaccine efficacy in livestock, specifically cattle. It investigates how these formulations can present antigens more effectively and stimulate robust immune responses, with QS-21 showing promise due to its broader activation of innate immune […]

This paper is about another adjuvant formulation method with QS-21. This study presents a novel approach to improving the safety and efficacy of QS-21, a potent saponin adjuvant widely used in vaccine formulations, by utilizing cooperative supramolecular integration within amphiphilic PEO–PPO triblock copolymer micelles. Unlike traditional lipid-based systems, the authors demonstrate that QS-21 can participate […]

This paper describes the development of a vaccine controlling Staphylococcus aureus-induced mastitis in dairy cattle, using saponin-based adjuvants, NanoQuil, a third-generation immunostimulating complex (ISCOM) nanoparticle formulation. As mastitis remains a major health and economic concern in dairy farming worldwide, with current vaccines showing limited efficacy, this study's focus on a novel NanoQuil adjuvant combining with […]

This paper is significant for its innovative use of the saponin adjuvant QS-21 in a self-adjuvanting vaccine targeting melanoma. The authors designed a GM3-based conjugate vaccine that incorporates lipid A mimetics as carriers, enabling strong immune responses without the need for traditional protein carriers. Notably, the study demonstrates a synergistic effect when QS-21, a purified […]

This review paper provides a comprehensive overview of recent advances in the heterologous biosynthesis of QS saponins, with a particular focus on QS-21. It highlights the significance of QS-21 in enhancing immune responses in vaccines, especially for diseases like influenza, COVID-19, and various cancers, emphasizing its broad biomedical applications. The paper is unique in systematically […]

This article presents a compelling case for the development of an Epstein–Barr virus (EBV) vaccine, emphasizing the potential role of saponin-based adjuvants such as Matrix-M in enhancing vaccine efficacy. The paper highlights recent mechanistic insights into how EBV reprograms autoreactive memory B cells, particularly through interactions involving EBNA2 binding at autoimmune risk loci, linking persistent […]

This phase III open-label study evaluates the immunogenicity and safety of co-administering two adjuvanted vaccines: the AS01E-adjuvanted RSV prefusion F protein vaccine (Arexvy) and the AS01B-adjuvanted recombinant herpes zoster subunit vaccine (Shingrix) in adults aged 50 years and older. Uniquely, the study investigates the co-administration of two vaccines containing the same AS01 adjuvant system, an […]

This study introduces a novel, versatile liquid chromatography method coupled with charged aerosol detection (LC-CAD) for the reliable quantification and stability monitoring of QS-21, widely used in vaccine formulations. Uniquely leveraging fused-core phenyl hexyl stationary phases and in silico optimization, the method effectively separates QS-21 isomers and its hydrolyzed degradant, QS-21 HP, with high sensitivity […]
