Protein nanoparticles, as antigen display carriers, can effectively help to improve the stability and immunogenicity of antigens due to their similar size to natural pathogens. Clinical trials have shown that protein nanoparticles can be used in the development of novel vaccines. This paper reviews the immunological properties of protein nanoparticle vaccine and the application in vaccine research and development, aiming to provide reference for further research of protein nanoparticle.
