Disclosed herein are methods of preparing peptide specific cytotoxic T cells (CTLs) against an emerged strain of a virus. The methods include providing an initial peptide composition specific to a prior strain of a virus, against which prior CTLs were sensitized, wherein the prior CTLs have reduced efficacy against an emerged strain of a virus relative to their efficacy against the prior strain of the virus; identifying an immunodominant peptide against a prior strain of a virus in an initial peptide composition; reducing the proportion of an immunodominant peptide in an initial peptide composition to yield an immunodominant-peptide-diluted peptide composition; and sensitizing mononuclear cells with an immunodominant-peptide-diluted peptide composition, thereby producing expansion of the peptide specific CTLs against an emerged strain of a virus. The virus can be SARS-COV2 (COVID-19) and the emerged strain can be Delta or Omicron BA.2.75.

A novel treatment regimen is provided for the treatment of autoimmune disorders. Said novel treatment regimen provides for an efficacious treatment of autoimmune disorders with an advantageous safety profile and/or a high quality of life for the patient. Said novel treatment regimen provides for an advantageous benefit-risk ratio for patients endangered by the risk of infections.

The present invention relates to immunization of hypo-responsive groups of individuals. In particular, the present invention provides methods and compositions for eliciting a potent immune response to hepatitis B virus in individuals in need thereof.

The present invention is drawn to a next generation nano vaccine platform by using structure-based design to utilize the conserved or less variable or highly immunogenic domains or epitopes and displaying it in a nano cage and produces it in as nanoparticle protein in prokaryotic expression system. The present invention is illustrated in detail by a vaccine design and construct for SARS CoV-2, SARS-CoV-2 variants, betacorona viruses, Monkey pox virus and Dengue virus.

The invention relates to an anti-coronavirus polypeptide as well as derivatives and application thereof, provides the anti-coronavirus polypeptide, and provides cholesterol-containing derivatives of the polypeptide on the basis of the anti-coronavirus polypeptide. Particularly, the original strain and the variant strain of the SARS-COV-2 have an unexpected inhibition effect, can be used for preparing medicines or vaccines for preventing or treating the new coronavirus, and have great prevention or treatment potential.

Disclosed herein are cross-linked peptides either alone or conjugated to PEG(n)-cholesterol (or thiocholesterol) moieties useful for interfering with and inhibiting or preventing coronavirus infection (e.g., infection by SARS-CoV-2). Also disclosed are methods of treating and/or preventing a coronavirus infection (e.g., COVID-19.

Described are lipopeptides that inhibit coronavirus fusion to a host cell. Thus a therapeutic for treating or preventing the common cold is described along with methods of inhibiting and/or treating an alphacoronavirus infection. The lipopeptides comprise a peptide unit comprising an amino acid sequence having a high degree of sequence identity to a sequence from the C-terminal heptad repeat of a betacoronavirus S protein, such as that of SARS-CoV-2.
