Solution Overview
Problem
Current vaccines face challenges due to low immunogenicity, which limits their effectiveness in preventing and treating various diseases, and there is a need for improved adjuvant compositions that can modulate immune responses to enhance antigen presentation and innate immunity.
Innovation Solution
Development of adjuvant compositions comprising a pharmaceutically acceptable carrier, flavonoids, tannins, and vitamins, such as catechin, gallic acid, and vitamins A and E, which can be administered through various routes to modulate immune responses by enhancing or suppressing antigen-presentation activity and innate immune responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional vaccines are used, then they can prevent some diseases, but they have low immunogenicity which limits their effectiveness
Solution Approach 1:
The patent combines multiple adjuvant components (flavonoids, tannins, vitamins) with antigens to create composite vaccine formulations. This composite approach enhances the overall immunogenicity by leveraging the synergistic effects of different adjuvant types, thereby improving vaccine effectiveness without requiring increased antigen quantity.
Solution Approach 2:
The patent modifies the chemical and physical parameters of the vaccine formulation by incorporating specific adjuvants that alter the immunogenic properties. These parameter changes include modifying the molecular structure interactions, solubility characteristics, and immune recognition properties to enhance vaccine effectiveness while maintaining appropriate antigen levels.
2Reliability
If adjuvant compositions are developed to enhance immune response, then antigen presentation activity is improved, but the complexity of composition increases
Solution Approach 1:
The patent divides the adjuvant system into distinct functional segments: flavonoids for immune modulation, tannins for antigen stabilization, and vitamins for immune support. This segmentation allows each component to perform its specific function optimally while maintaining a manageable overall composition structure that can be systematically formulated and controlled.
3Reliability
If immune response is enhanced through adjuvants, then vaccine efficacy is improved, but pro-inflammatory cytokine production may increase
Solution Approach 1:
The patent utilizes the controlled production of pro-inflammatory cytokines as a beneficial signal to activate the immune system. By incorporating adjuvants that modulate cytokine profiles, the formulation converts potential harmful inflammation into a controlled immune activation mechanism that enhances vaccine efficacy while maintaining safety through balanced immune response regulation.

AI summary
The present invention provides adjuvant compositions that are capable of modulating the immune response in a subject, including enhancing or suppressing the immune response. These adjuvant compositions may also be used to enhance or suppress the immunogenicity of antigens by enhancing or suppressing antigen-presentation activity, enhancing or suppressing innate immune responses through activation or suppression of, e.g., natural killer cells, and/or direct activation of subsets of B and/or T cells. Also provided are methods of making the adjuvant compositions as well as methods of using the adjuvant compositions. In certain embodiments, the compositions comprise combinations of the following: a pharmaceutically acceptable carrier, a flavonoid, a tannin and a vitamin. The pharmaceutically acceptable carrier may be selected from mustard oil, corn oil, olive oil, grape seed oil, oleic acid and squalene; the flavonoid may be a catechin, such as EGCG and CH; the tannin may be gallic acid; and the vitamin may be selected from Vitamin A, Vitamin E and Vitamin D. The compositions may further comprise an antigen.
