{Abstract}: To elicit potent humoral immunity and produce adequate neutralizing antibody especially in the genital tract and eventually to promote its immunogenicity, we designed an Eppin B-cell-dominant-epitope-based mimovirus vaccine with an RGD motif which can be nasally inoculated into male mice. Our results indicate that this immune strategy successfully generated a high antibody response with significantly higher anti-Eppin IgA in the genital tract, and eventually achieve significant inhibition of fertility without any interference with testis function and alteration in structural integrity. The fertility rate of the females mating with the vaccinated males declined and the progeny size was greatly reduced, but the contraceptive efficacy was still far from that of immunocontraceptives for human use. However, the research showed a new contraceptive vaccine construction and inoculation avenue, that is, mimovirus vaccine delivered nasally. Further investigation geared toward improving fertility inhibition efficacy using this inoculation strategy still remains to be explored.
