Vaccine vectors and methods of using the vaccine vectors to enhance the immune response to an Apicomplexan parasite and reduce the morbidity or mortality associated with subsequent infection are provided herein. The vaccine vectors include a polynucleotide encoding a Rhomboid polypeptide and optionally include an immune-stimulatory polypeptide suitably expressed on the surface of the vaccine vector.

Brachyury protein can be used to induce Brachyury-specific CD4+ T cells in vivo and ex vivo. It is also disclosed that Brachyury protein can be used to stimulate the production of both Brachyury-specific CD4+ T cells and Brachyury-specific CD8+ T cells in a subject, such as a subject with cancer. In some embodiments, the methods include the administration of a Brachyury protein. In additional embodiments, the methods include the administration of a nucleic acid encoding the Brachyury protein, such as in a non-pox non-yeast vector. In further embodiments, the method include the administration of host cells expressing the Brachyury protein.

The present invention relates to a liquid composition of live Mollicutes bacteria and a stabiliser, whereby the stabiliser is a natural deep-eutectic solvent (NADES). In this liquid composition the live Mollicutes are stabilised without need for freezing or freeze-drying. This allows various advantageous uses in diagnostics and medicine, specifically as a liquid vaccine for use against infection or disease caused by Mollicutes bacteria, for human- or non-human animals.

A method and system for the treatment of Monarch butterflies (Danaus plexippus Kluk (Lepidoptera: Nymphalidae) to protect them from various life-threatening conditions, including the negative effects of various pesticides, provides Monarch butterflies with the ability to assimilate and degrade pesticides such as neonicotinoids and fipronil. Certain embodiments involve the inoculation of flowers by honey bees with desired bacteria that are able to degrade pesticides, such that when Monarch butterflies visit such flowers, they are exposed to such bacteria, transforming the microbiome of the Monarch butterflies so that pesticides can be degraded, thus enhancing the health of the Monarch butterflies.

The present document describes a method of inhibiting cancer tumor growth in a patient in need thereof, comprising at least a first treatment comprising steps a) and b): a) administering to the patient an immune adjuvant in combination with a therapeutic monoclonal antibody specific for a tumor associated antigen; and b) administering to the patient the immune adjuvant; and a final treatment consisting of administering to the patient the therapeutic monoclonal antibody specific for a tumor associated antigen, wherein time between step a) and step b) is a time sufficient for treatment of the patient with the immune adjuvant, and wherein time between the step b) and the final treatment is from about 10 to about 14 weeks.

The invention relates generally to vaccine compositions that are capable of eliciting and sustaining an immune response in a subject. The vaccine composition comprises a water-in-oil emulsion and a plurality of immunogen loaded hydrogel particles surrounded with a cationic polymer shell dispersed in the aqueous phase of the emulsion.

The present invention provides a vaccine formulation for use in the prevention and/or treatment of a cancer, comprising a complex of a hyaluronic acid derivative having an introduced hydrophobic group, and an antigen.

The present invention provides both QuilA-loaded chitosan (QAC)-encapsulated DNA vaccine compositions and viral vaccine compositions that encode a SARs-CoV-2 spike (S) protein, a SARs-CoV-2 nucleocapsid (N) protein, or both the S protein and the N protein. Additionally, the present invention provides methods in which the disclosed vaccines are administered to a subject to induce an immune response against SARS-CoV-2.

Provided herein is an E. coli O polysaccharide, O25B. Also provided herein are prokaryotic host cells containing enzymes (e.g., glycosyltransferases) used in O25B production. The host cells provided herein produce O25B bioconjugates, wherein said bioconjugates contain O25B linked to a carrier protein. Further provided herein are compositions, e.g., pharmaceutical compositions, including O25B and/or bioconjugates containing O25B. Such compositions can be used as vaccines against infection with ExPEC, and may further include one or more additional bioconjugates.

The present invention belongs to the field of biological medicine, particularly to a novel tumor vaccine. In order to solve the problem in the art that no technical scheme is available for generating lasting and high-effective anti-tumor immune responses, the present invention provides a tumor vaccine mainly containing a complex as a main active ingredient, wherein the complex is formed by nucleic acid, especially replicable nucleic acid not expressing exogenous gene, and cationic biomaterial. The nucleic acid and the cationic biomaterial in the tumor vaccine according to the present invention have synergistic interactions on direct killing of tumor cells, and induction of the innate immune response and adaptive immune response of body against tumor. In addition, the prepared tumor vaccine has simple drug component and is easy to produce and maintain quality control. The tumor vaccine has a good prospect for application.
