The present disclosure is directed to a relief system for the effective detection, prevention, and treatment of COVID-19, including (1) serological diagnostic assays for the detection of viral infection and epidemiological surveillance, (2) high-precision, site-directed peptide immunogen constructs for the prevention of infection by SARS-CoV-2, (3) receptor-based antiviral therapies for the treatment of the disease in infected patients, and (4) designer protein vaccine containing S1-RBD-sFc. The disclosed relief system utilizes amino acid sequences from SARS-CoV-2 proteins as well as human receptors for the design and manufacture of optimal SARS-CoV-2 antigenic peptides, peptide immunogen constructs, CHO-derived protein immunogen constructs, long-acting CHO-derived ACE2 proteins, and formulations thereof, as diagnostics, vaccines, and antiviral therapies for the detection, prevention, and treatment of COVID-19.

The invention is directed to a coding RNA for a Rotavirus vaccine. The coding RNA comprises at least one coding region encoding at least one antigenic peptide or protein of a Rotavirus, in particular VPS* of a Rotavirus, or immunogenic fragment or immunogenic variant thereof. The present invention is also directed to compositions and vaccines comprising said coding RNA in association with a polymeric carrier, a polycationic protein or peptide, or a lipid nanoparticle (LNP). Further, the invention concerns a kit, particularly a kit of parts comprising the coding RNA, or the composition, or the vaccine. The invention is also directed to a kit or kit of parts, medical treatments, and the first and second medical uses.

Self-replicating RNA molecules encoding hepatitis B virus (HBV) vaccines are described. Methods of inducing an immune response against HBV or treating an HBV-induced disease, particularly in individuals having chronic HBV infection, using the disclosed self-replicating RNA molecules are also described. Kits comprising the disclosed self-replicating RNA molecules are also described.

The present invention is directed to a method of treating poultry hatchlings in a hatchling tray. The method comprises of providing a soft gel form capable of being dispensed through a spray nozzle, providing a spray dispensing apparatus, the apparatus being capable of delivering a predetermined volume of the gel as a plurality of small beadlets through a plurality of nozzles, placing the hatchling tray containing the hatchlings beneath the nozzles of the dispensing apparatus, dispensing the predetermined volume of the soft gel containing the therapeutic agent as small beadlets into the hatchling tray and allowing the hatchlings to consume the beadlets. The present invention is also directed to a dispensing apparatus for dispensing a therapeutic agent in a soft gel into a hatchling tray of poultry hatchlings.

The present application relates to composition of matter, processes and use of composition of matter relating to flavivirus proteins, peptides, and epitopes, for example, for therapeutic or preventative vaccination against one or more flavivirus serotypes or species, and/or for inducing, enhancing, or sustaining an immune response against at least one flavivirus serotype or species. The flavivirus may be for example the Zika and/or Dengue virus.

The invention provides long immunogenic peptides for treating diseases related to severe acute respiratory syndrome coronaviruses, such as SARS-CoV-2 or SARS-CoV-1. The invention also provides immunogenic compositions and vaccines comprises long immunogenic peptides of the invention and method of therapeutic treatment or prevention of SARS-CoV-related diseases comprising administration of immunogenic peptides according to the invention.

The present invention relates to modular systems for vaccination against infectious agents that involves the delivery of, e.g., exosome-loaded, antigen-encoding mRNAs to and into cells and tissues of the immunized subject. The present invention also relates to compositions and methods for the design, preparation, manufacture, formulation, and/or use of vaccines, e.g., nucleic acid vaccines, loaded into extracellular vesicles, e.g., exosomes loaded with synthetic mRNAs encoding multiple surface and cytoplasmic antigens of interest, e.g., antigenic polypeptides derived from an infectious virus, e.g., SARS-CoV-2, designed to elicit strong humoral and cellular immune responses due to the simultaneous expression of antigens in their native state and as exosome-associated antigens.
