Provided herein are non-naturally occurring, broadly reactive, pan-epitopic antigens derived from Dengue virus that are immunogenic and elicit a broadly reactive immune response, such as a broadly reactive neutralizing antibody response, against Dengue virus subtypes following introduction into a subject. Also provided are non-naturally, broadly reactive occurring immunogens, immunogenic compositions, vaccines, subviral particles (SVPs), and virus-like particles (VLPs) comprising Dengue virus proteins or encoding polynucleotides. Methods of generating an immune response in a subject by administering the immunogens, vaccines, SVPs, VLPs, or immunogenic compositions thereof are provided. In particular, the immunogens comprise a Dengue virus protein, or an antibody binding portion thereof.
