Plants and plant produced compositions which include Coronavirus S proteins are disclosed. These may be used as vaccines, boosters or immune modulators. The compositions have been shown to reduce the inflammatory cytokine response by altering cytokine levels when administered to an animal. The compositions may be used as an immune modulator to reduce/ameliorate or prevent the cytokine storm often associated with Coronavirus or other virus infection. The compositions may also be used to produce additive protection when administered with any vaccine composition to increase vaccine effectiveness. The compositions when used as vaccines have been shown to protect newborn animals through passive immunity.

The present invention includes composition and methods for composition for the oral delivery of a therapeutic agent that reduces, desensitizes, or prevents food, respiratory and other allergies. First pollen is cleaned to remove naturally-occurring allergic plant proteins to form a cleaned pollen and a therapeutically effective amount of an allergen is introduced into the cleaned pollen. The allergen-loaded cleaned pollen is delivered to a subject in need of therapy.

A buffer free, acid stable, low dose volume rotavirus vaccine is disclosed. The vaccine is available in dose volume of less than 1 ml per dose for oral administration and it is without any buffer. The vaccine also does not require pre or post administration of any antacid at the time of oral administration of the vaccine to the subject to neutralize the stomach acid. The vaccine exemplifies nominal drop in vaccine titer at pH 2-4 for a time span of 30 minutes. The vaccine is stable at −20° C. for at least 60 months.

The present disclosure provides a method of treating a solid tumor cancer. The method includes administering a combination to a subject in need thereof. The combination includes at least two chemotherapy agents and a dose of a composition consisting essentially of attenuated Salmonella typhimurium. The present disclosure also provides an anti-tumor agent for use in a method of treating cancer. In such instances, the anti-tumor agent may include the combination.

Disclosed herein, in certain embodiments, are recombinant Arc and endogenous Gag polypeptides, and methods of using recombinant Arc and endogenous Gag polypeptides.

The present disclosure provides, in part, peptide self-assemblies that are made into tablet form and methods of making and using the same. In some embodiments, the disclosure provides methods and formulations for a tabletized form of a vaccine, particularly a vaccine comprising self-assembling peptide-polymer nanofibers, an excipient and an adjuvant. Methods of making and using the tablet formulation are also provided.

This disclosure features methods and compositions for treating diseases of the gastrointestinal tract with an integrin inhibitor. In particular, the disclosure features the topical treatment of sections and subsections of the gastrointestinal tract by integrin inhibitors (like vedolizumab) using an ingestible device that can detect its whereabouts in the Gl tract by using reflectance and which is programmed to release the drugs at a given site or proximal thereto, to treat gastrointestinal inflammatory diseases. The device has hardware storage devices with instructions on board to determine the location and release the formulations. Combination therapies are claimed as well in which the integrin inhibitor is added systemically and another agent (e.g. JAK inhibitor, TNF-alpha inhibitor or IL-12/IL-23 inhibitor) is added topically by means of the ingestible device. The topical administration is said to reduce the side effects associated with systemic treatment.

Provided herein are genetically engineered Vibrio cholerae bacterial strains, compositions including the bacterial strains, and methods of using the same for the prevention of Vibrio cholerae infection in a subject.

Provided is a swine fever antigen fused with a porcine Fc fragment, and more particularly, to a vaccine composition having an autoimmune-enhancing effect by binding the Fc fragment to a swine fever antigen, and a preparation method thereof.

This invention relates to a method of treating a dog for canine diseases comprising administering to the dog therapeutically effective amounts of a vaccine, wherein the vaccine comprises viral antigens, a bacterin, or both, and wherein the vaccine is administered subcutaneously or orally according to the schedules provided herein.
