Example Embodiment
[0041] Example 1
[0042] This embodiment provides a composite adjuvant composed of CpG oligodeoxynucleotide and aluminum hydroxide; wherein, the mass ratio of CpG oligodeoxynucleotide and aluminum hydroxide is 1:0.6.
[0043] This embodiment further provides a combination of the compound adjuvant and the novel coronavirus COVID-19 recombinant vaccine.
[0044] Specifically: add CpG oligodeoxynucleotide adjuvant and aluminum hydroxide adjuvant to the vaccine stock solution filtered by a 0.22 μm filter membrane, so that the concentration of CpG adjuvant is 0.5 mg / dose and the content of aluminum hydroxide adjuvant is 0.3 mg / dose, vaccine antigen content 20μg / dose. The vaccine number obtained in this example is recorded as 20200401.
