摘要: The present invention relates to a novel coronavirus vaccine using a TLR7 agonist conjugated peptide as an antigen and an emulsion as an adjuvant. An antigen polypeptide of the conjugated peptide is a polypeptide derived from an S protein of SARS-COV-2, and the adjuvant is an oil-in-water nanoemulsion containing squalene. The conjugated peptide nanoemulsion vaccine preparation of the present invention is thermally stable, and can induce a high level of protective humoral immune response in a cynomolgus monkey, and the neutralizing antibody titer of antiserum after immunization of cynomolgus monkey is high, such that invasion of wild-type strain and mutant novel coronavirus can be blocked. The vaccine of the present invention has a nearly complete protection effect on the upper and lower respiratory tracts of the cynomolgus monkey in a cynomolgus monkey SARS-COV-2 challenge test. The nanoemulsion vaccine of the present invention is fast and convenient to prepare, and can realize large-scale production in a short term for coping with the novel coronavirus outbreak.
