Vaccine
The disclosure provides immunogenic compositions comprising human picornavirus peptides derived from structural proteins of the virus, constructs comprising the peptides, the peptides themselves and their use in the prevention of picornavirus infection and disease. Particular peptides from VP4 and VP1 are disclosed.
1. An immunogenic composition comprising:
(a) a fusion protein comprising a carrier protein coupled to a human rhinovirus (HRV) peptide, said HRV peptide comprising no more than 20 amino acids from the N terminus of HRV VP4 and comprising a sequence selected from SEQ ID NO:5, SEQ ID NO:6, and SEQ ID NO:7; and
(b) a pharmaceutically acceptable diluent, excipient or carrier.
2. The immunogenic composition of claim 1 , wherein said HRV peptide consists of a sequence selected from:
HRV14 (B):
[SEQ ID NO: 5]
1-GAQVSTQKSGSHENQN-16;
HRV100 (A-M):
[SEQ ID NO: 6]
1-GAQVSRQNVGTHSTQN-16;
and
HRV_C_026:
[SEQ ID NO: 7]
1-GAQVSRQSVGSHETMI-16.
3. The immunogenic composition of claim 1 , wherein said carrier protein is CRM197.
4. The immunogenic composition of claim 1 , further comprising an adjuvant.
5. The immunogenic composition of claim 4 , wherein the adjuvant comprises at least one of: an aluminium salt; 3-O-deacylated monophosphoryl lipid A (3D-MPL); QS21; and liposomes.
6. A fusion protein comprising a carrier protein coupled to a HRV peptide, said HRV peptide comprising no more than 20 amino acids from the N terminus of VP4 and comprising a sequence selected from SEQ ID NO:5, SEQ ID NO:6, and SEQ ID NO:7.
7. The fusion protein of claim 6 , wherein said HRV peptide consists of an amino acid sequence selected from:
HRV14 (B):
[SEQ ID NO: 5]
1-GAQVSTQKSGSHENQN-16;
HRV100 (A-M):
[SEQ ID NO: 6]
1-GAQVSRQNVGTHSTQN-16;
and
HRV_C_026:
[SEQ ID NO: 7]
1-GAQVSRQSVGSHETMI-16.
8. A method for preparing an immunogenic composition which method comprises combining: a fusion protein comprising a carrier protein coupled to a human rhinovirus (HRV) peptide, said HRV peptide comprising no more than 20 amino acids from the N terminus of HRV VP4 and comprising a sequence selected from SEQ ID NO:5, SEQ ID NO:6, and SEQ ID NO:7, and a pharmaceutically acceptable diluent, excipient, or carrier.
