The provided sources, a patent application and a research paper, both authored in part by Sung-Hou Kim, focus on the genomic analysis of SARS-CoV-2 (SC2) and the design of "pan-valent" vaccines. The authors classify SC2 variants into four Major Genomic Groups (MGGs), each characterized by Highly-Conserved Variant Genotypes (HCVGs), with some HCVGs being inherited across these groups. This observational basis informs their computational method for designing a novel vaccine type that aims to induce broad immunity against both current and future viral strains, specifically targeting the S and N genes due to their high concentration of these crucial HCVGs.
