Disclosed is an immunogen comprising a fusion protein, wherein the fusion protein comprises a Zika virus (ZIKV) envelope protein, optionally a signal peptide, and a multimerization domain. The signal peptide is a premembrane (prM) signal peptide, an IgG signal peptide, or a human secretory signal peptide hidden Markov model, and the multimerization domain is an immunoglobulin Fc domain, a T4 fibritin foldon trimerization domain, or a human collagen XV trimerization domain. Nucleic acids, vectors, and microneedle arrays including these compositions are disclosed. Methods of producing an immune response to ZIKV are also disclosed.
