Abstract: Adjuvants are immune stimulators that enhance and regulate the immune response of vaccine antigens.They can produce stronger immune response when used together with antigens.Adjuvants can activate the host's innate immune system.When adjuvants and antigens are injected into the body at the same time or in advance, they can change the shape of antigens and prolong their retention in the body, promote the presentation ability of mononuclear phagocytes to antigens and stimulate the proliferation and differentiation of lymphocytes, thereby enhancing the host's immune response to antigens or changing the type of immune response.Adjuvants have a history of more than 100 years.At present, the most widely used vaccine adjuvant is aluminum adjuvant.Traditional inactivated vaccines rely largely on aluminum salt based compounds as the main adjuvant.However, in recent years, with the rapid development of genetic engineering technology and biotechnology, recombinant vaccines, genetic engineering vector vaccines, nucleic acid vaccines and other novel vaccines have been gradually developed.Compared with traditional vaccines, these novel vaccines often have problems such as poor immune response.Due to the early antigen impurity, the traditional aluminum adjuvant can no longer meet the needs.In order to resolve the problem of poor immunogenicity of novel vaccines, researchers are committed to developing novel broad-spectrum and efficient vaccine adjuvants to enhance the efficacy of novel vaccines.Novel vaccine adjuvants have various types, different functions and complex mechanisms.They can be divided into novel oil emulsion adjuvants, liposome adjuvants, CpG oligonucleotide adjuvants, cytokine adjuvants, nano adjuvants, polysaccharide adjuvants and complex system adjuvants.Therefore, the development history, mechanism of action and classification of novel vaccine adjuvants were analyzed and summarized in this review, which would provide reference for the development of novel vaccine adjuvants.
