## Abstract

The invention refers an improved vaccine against infections with pathogens, especially viral pathogens, comprising an antigen, a peptide of the formula R1—XZSZN—XZX—R2 and an immunostimulatory deoxynucleic acid containing deoxyinosine and/or deoxyuridine residues.

## Claims

### Claim 2 (depends on 1)

The vaccine of claim 1, further comprising an Al(OH)3 adjuvant.

### Claim 3 (depends on 1)

The vaccine of claim 1, wherein the HBV antigen is Hepatitis B surface antigen (HBsAg).

### Claim 4 (depends on 1)

The vaccine of claim 1, further comprising a polycationic peptide.

### Claim 5 (depends on 1)

The vaccine of claim 1, further comprising an oligodeoxynucleotide containing a CpG-motif.

### Claim 6 (depends on 1)

The vaccine of claim 1, further comprising a polycationic peptide and an oligodeoxynucleotide containing a CpG-motif.

### Claim 7 (depends on 1)

A method of improving protective efficacy of a vaccine against an HBV infection comprising:
obtaining a peptide comprising the sequence KLKL5KLK (SEQ ID NO: 6) and an I-ODN of claim 1, wherein the I-ODN comprises oligo-d(IC)13 (SEQ ID NO: 21); and
administering the peptide and the I-ODN with a vaccine against an HBV infection to a subject;
wherein efficacy of the vaccine against an HBV infection is improved in the subject.

### Claim 8 (depends on 1)

A method of improving an antigen-specific type 1 response of a vaccine against an HBV infection and preserving or increasing a type 2 response of said vaccine comprising:
obtaining a peptide comprising the sequence KLKL5KLK (SEQ ID NO: 6) and an I-ODN of claim 1, wherein the I-ODN comprises oligo-d(IC)13 (SEQ ID NO: 21); and
administering the peptide and the I-ODN with a vaccine against an HBV infection to a subject;
wherein the antigen-specific type 1 response to the vaccine against an HBV infection is improved in the subject and the type 2 response to the vaccine is preserved or increased in the subject.

administering the peptide and the I-ODN with a immunogenic composition against an HCV infection to a subject;
wherein efficacy of the immunogenic composition against HCV infection is improved in the subject.

### Claim 16 (depends on 9)

A method of improving an antigen-specific type 1 response of a immunogenic composition against an HCV infection and preserving or increasing a type 2 response of said immunogenic composition comprising:
obtaining a peptide comprising the sequence KLKL5KLK (SEQ ID NO: 6) and an I-ODN of claim 9, wherein the I-ODN comprises oligo-d(IC)13 (SEQ ID NO: 21); and
