Abstract: The disclosure relates to vaccination compositions, for example, against human papillomavirus, Zika virus, and flu virus. The disclosure also relates to vectors for producing the virus-like particles and immune complex platforms of the vaccination compositions.

Abstract: The disclosure relates to immunoglobulin variants that are useful for the design of vaccinations against a variety of athogens and their method of production and use. In some aspects, the immunoglobulin variants are variants of IgG, for example, the 6D8 antibody.

Abstract: Improved plant transient expression systems using optimized geminiviral vectors that efficiently produce heteromultimeric proteins are described herein. Examples of high yields are shown herein, including two, three, or four fluorescent proteins coexpressed simultaneously. Various antibodies were produced using the optimized vectors with special focus given to the creation and production of a chimeric broadly neutralizing anti-flavivirus antibody. The variable regions of this murine antibody, 2A10G6, were codon optimized and fused to a human IgG1. Analysis of the chimeric antibody showed that it was efficiently expressed in plants, can be purified to near homogeneity by a simple one-step purification process, retains its ability to recognize the Zika virus envelope protein, and induce an immune response against Zika virus. Two other monoclonal antibodies were produced at similar levels.
