Vaccine composition containing a promoter peptide
View Patent ↗A vaccine having a good vaccination effect, which comprises an antigen; a peptide selected from the group consisting of a peptide having the amino acid sequence of SEQ ID NO: 1, a peptide having the amino acid sequence of SEQ ID NO: 2, and a peptide derived from a peptide having the amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 2; and an immune activator.
1. A vaccine composition comprising: a specific antigen, wherein an amount of said specific antigen causes an immune response; a peptide selected from the group consisting of a peptide having the amino acid sequence of SEQ ID NO: 1, a peptide having the amino acid sequence of SEQ ID NO: 2, and a peptide derived from a peptide having the amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 2; and an immune activator, in a physiologically acceptable carrier.
2. The vaccine composition of claim 1 , wherein the antigen is a viral protein.
3. The vaccine composition of claim 1 , wherein said antigen is capable of eliciting an immune response against viral hepatitis, influenza, diphtheria, tetanus, pertussis, measles, mumps, rubella, polio, pneumococcus, herpes, respiratory syncytial virus, haemophilus influenza type b, varicella-zoster virus, or rabies.
4. The vaccine composition of claim 1 , wherein the antigen is a recombinant protein.
5. The vaccine composition of claim 1 , wherein the antigen is a recombinant viral protein.
6. The vaccine composition of claim 1 , wherein the antigen is an HCV protein.
7. The vaccine composition of claim 1 , wherein the antigen is an HCV E2 protein.
8. The vaccine composition of claim 1 , wherein the antigen is a recombinant HCV E2 protein.
9. A vaccine composition comprising: an HCV E2 protein; a peptide selected from the group consisting of a peptide having the amino acid sequence of SEQ ID NO: 1, peptide having the amino acid sequence of SEQ ID NO: 2, and a peptide derived from a peptide having the amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 2; and an immune activator, in a physiologically acceptable carrier.
10. The vaccine composition of claim 1 , wherein the amount of the peptide ranges from 0.001 to 1 wt % based on the total weight of the vaccine.
11. The vaccine composition of claim 1 , wherein the immune activator is aluminum hydroxide (alum), Freund's adjuvant, or a mixture thereof.
