Abstract

The present disclosure provides a microemulsion-based vaccine delivery system, and further provides a preparation method and an application thereof. Using the microemulsion absorbing a series of metal ion compounds, and adding an antigen in a preparation process, antigen entrapment can be realized and a stable vaccine preparation is obtained. The prepared vaccine can effectively be taken up by an antigen-presenting cell and effectively delivered to lymph nodes to induce an antigen-specific immune response, and the same has a wide application prospect.
