Examples
Embodiment 1
[0019] The dosage of the chondroitin sulfate B adjuvant provided in this example is 5 μg.
[0020] The hepatitis A vaccine containing chondroitin sulfate B adjuvant provided in this example is: add 5 μg of chondroitin sulfate B to each vaccine dose, add chondroitin sulfate B to hepatitis A (HAV) antigen, and then add normal saline to 200 μL , and mix uniformly according to routine to obtain the hepatitis A vaccine agent containing chondroitin sulfate B.
[0021] Wherein, chondroitin sulfate B is a commercially available product, and its molecular formula is (C 14 h 21 NO 14 S) n , with a molecular weight of about 41KDa, purchased from SiGMA, USA; the HAV antigen was a commercially available 18EU HAV antigen solution with a titer of 256EU / ml, purchased from the Institute of Medical Biology, Chinese Academy of Medical Sciences and Peking Union Medical College.

Embodiment 3
[0047] The dosage of the chondroitin sulfate B adjuvant provided in this example is 85 μg.
[0048] The hepatitis A vaccine containing chondroitin sulfate B adjuvant provided in this example is: add 85 μg of chondroitin sulfate B to each vaccine dose, add chondroitin sulfate B to hepatitis A (HAV) antigen, and then add normal saline to 200 μL , and mix uniformly according to routine to obtain the hepatitis A vaccine agent containing chondroitin sulfate B. Wherein, chondroitin sulfate B and HAV antigen are the same as in Example 1;
[0049] The immune test of the hepatitis A vaccine containing the chondroitin sulfate B adjuvant obtained in this example is the same as in Example 1, and the results are shown in Table 3.
[0050] Table 3 shows the serum anti-HAV IgG antibody levels of mice in each experimental group within 16 weeks after using the adjuvant provided in Example 3.
