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. 11,857,621.

Summary of the Inventive Concept

A novel, next-generation synthetic pDNA vaccine platform that induces a robust and broad immune response against SARS-CoV-2, leveraging optimized epitopes, chimeric proteins, and personalized approaches to revolutionize COVID-19 vaccination.

Background and Problem Solved

The original patent, 'Synthetic pDNA vaccines against COVID-19', introduced a pioneering approach to combat the pandemic. However, as the virus continues to evolve, there is an urgent need for more effective and adaptable vaccine technologies. The new inventive concept addresses the limitations of the original patent by incorporating cutting-edge design principles, epitope optimization, and personalized medicine to create a more potent and durable immune response.

Detailed Description of the Inventive Concept

The next-generation synthetic pDNA vaccine platform consists of several key components: 1) optimized epitopes engineered for enhanced antigen presentation and T-cell activation, 2) chimeric S proteins that induce a broad immune response against SARS-CoV-2, 3) nucleic acid sequences encoding S protein variants with improved stability and immunogenicity, and 4) personalized vaccine approaches tailored to individual genetic profiles. These innovations enable a more effective and adaptable immune response, reducing the risk of antibody-dependent enhancement and providing long-term protection against SARS-CoV-2.

Novelty and Inventive Step

The new claims introduce several novel and non-obvious features, including the use of optimized epitopes, chimeric S proteins, and personalized vaccine approaches. These innovations provide a significant improvement over the original patent, enabling a more robust and durable immune response against SARS-CoV-2.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different optimization algorithms for epitope design, the incorporation of additional heterologous proteins, or the development of novel mucosal adjuvants. Variations of the personalized vaccine approach could involve the use of different genetic markers or machine learning algorithms to tailor the vaccine to individual profiles.

Potential Commercial Applications and Market

The next-generation synthetic pDNA vaccine platform has significant commercial potential in the vaccine industry, with applications in pandemic preparedness, public health, and personalized medicine. The market for COVID-19 vaccines is projected to continue growing, with an estimated value of $10 billion by 2025. The inventive concept's adaptability and effectiveness make it an attractive solution for governments, healthcare organizations, and pharmaceutical companies seeking to combat the ongoing pandemic.
