This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,562.

Summary of the Inventive Concept

A novel RNA delivery system adapted for specific, niche markets and operational environments, enhancing stability and effectiveness in high-temperature, high-security, disaster relief, and limited medical infrastructure settings.

Background and Problem Solved

The original patent addressed the need for non-viral delivery of RNA for immunization, but it did not provide solutions for specific, challenging environments. This inventive concept builds upon the original patent by adapting the RNA delivery system for unique operational environments, such as high-temperature, high-security, disaster relief, and limited medical infrastructure settings, where traditional RNA delivery systems may be ineffective.

Detailed Description of the Inventive Concept

The inventive concept comprises a system for delivering RNA to trigger multiple immune pathways in specialized environments, utilizing liposomes and mRNA molecules with modified nucleotides to enhance stability. The system is designed to operate effectively in high-temperature environments, high-security settings, disaster relief scenarios, and areas with limited medical infrastructure. The mRNA molecules can include sequences that encode influenza virus immunogens, and the 5′ cap nucleoside can be a 7-methylguanosine for enhanced stability. The system can be administered in various forms, including compositions, kits, and methods, to accommodate the specific needs of each environment.

Novelty and Inventive Step

The new claims introduce novel and non-obvious adaptations of the original RNA delivery system, including the use of modified nucleotides, specific sequences, and tailored compositions to address the unique challenges of high-temperature, high-security, disaster relief, and limited medical infrastructure environments. These adaptations provide a significant improvement over the original patent, enabling effective RNA delivery in previously unserved or underserved markets.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different types of liposomes, modified nucleotides, or mRNA molecules with varying sequences. Additionally, the system could be adapted for use in other specialized environments, such as extreme weather conditions or areas with limited access to medical resources.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including pharmaceuticals, biotechnology, and disaster relief. The system's ability to operate effectively in challenging environments makes it an attractive solution for governments, NGOs, and private organizations operating in these areas. The target market includes high-temperature industries, high-security facilities, disaster relief organizations, and areas with limited medical infrastructure.
