The invention involves RNA therapeutics featuring specific structural components, such as 5′ and 3′ untranslated regions and a coding sequence for viral epitopes. Various embodiments include modifications like nucleotide substitutions with analogs such as pseudouridine to improve RNA function. The invention also outlines methods for systematically altering RNA sequences to enhance stability and translation metrics, such as free energy and codon adaptation index.

Methodology

The described methods employ algorithmic approaches to optimize RNA sequences by altering nucleotides to increase structural stability. These methods include sampling unpaired nucleotides and substituting them to create more stable conformations. Metrics used to evaluate improvements include free energy, GC content, and structural features like hairpins and junctions. The invention also details the formulation of RNA molecules for medical applications, incorporating elements like lipid nanoparticles for delivery.

Applications and Advantages

The enhanced RNA molecules offer significant advantages for vaccine development, particularly against emerging viral threats like COVID-19 and Ebola. By improving RNA stability, the invention addresses logistical challenges in vaccine distribution, such as storage and transport limitations. The ability to formulate RNA for medical use in stable, effective forms could revolutionize the deployment of vaccines and therapeutics, reducing costs and increasing safety.
