Abstract: The present invention relates to polymersomes comprising a soluble encapsulated antigen, wherein said soluble encapsulated antigen is selected from the group consisting of: a polypeptide, a carbohydrate, a polynucleotide and combinations thereof. The present invention further relates to a method for production of encapsulated antigens in a polymersome as well as to polymersomes produced by said method. The present invention further relates to compositions comprising a polymersome of the present invention, isolated antigen presenting cells or hybridoma cells exposed to the polymersome or composition of the present invention. The present invention also relates to vaccines comprising polymersomes of the present invention, methods of eliciting an immune response or methods for treatment, amelioration, prophylaxis or diagnostics of a cancer, autoimmune or infectious disease, comprising providing polymersomes of the present invention.

Abstract: The present invention relates to eliciting an immune response in a subject by sole administration of an adjuvant, wherein the adjuvant is associated with a population of polymersomes.

Abstract: The present invention relates to a method of modulating Th1/Th2 immune response by administering a population of polymersomes having an associated antigen together with a population of polymersomes having an associated adjuvant as well as compositions comprising the two populations of polymersomes.

Abstract: The present invention relates to a polymersome comprising a soluble encapsulated antigen, wherein the soluble encapsulated antigen is a soluble fragment of a Spike protein of a human-pathogenic coronavirus, as well as a combination of a population of such polymersomes, and a second population of polymersomes comprising an encapsulated adjuvant. The present invention also relates to related methods, such as methods of treatment, kits, compositions, such a vaccine, and medical uses, such as in the treatment of a human-pathogenic coronavirus infection.

Abstract: The present invention relates to a method of eliciting an immune response in a subject by administration of an antigen and an adjuvant, wherein the antigen is associated with a first population of polymersomes, and wherein the adjuvant is associated with a second population of polymersomes, and wherein the two populations of polymersomes are administered to the subject. The present invention also relates to compositions such as vaccines comprising the two polymersome populations of the present invention, methods of eliciting an immune response or methods for treatment, amelioration, prophylaxis or diagnostics of a cancer, autoimmune or infectious disease, comprising providing polymersomes of the present invention.

Abstract: The present invention relates to polymersomes capable of eliciting an immune response, comprising: an antigen selected from the group consisting of: (a) a polypeptide; (b) a carbohydrate; (c) a polynucleotide; and (d) a combination of (a) and/or (b) and/or (c); wherein the antigen is conjugated to the exterior surface of the polymersome via a covalent bond. The present invention further relates to a method for production of antigens conjugated to a polymersome as well as to polymersomes produced by said method. The present invention further relates to compositions comprising a polymersome of the present invention, isolated antigen presenting cells or hybridoma cells exposed to the polymersome or composition of the present invention.
