The present invention discloses an engineered bacteriophage capable of binding to a commensal bacterium and inserting its genome polynucleotide into the commensal bacterium, but incapable of producing progeny, incapable of carrying out a lysogenic cycle and incapable of carrying out a lytic cycle within the commensal bacterium, wherein the engineered bacteriophage comprises a genome polynucleotide including at least one gene encoding at least one heterologous antigen(s) under the control of a promoter.

Immunogenic composition

The present invention discloses a recombinant bacteriophage comprising a phage genome polynucleotide including a gene encoding a heterologous antigen protein(s) and a killing gene encoding a protein that is capable of killing a host bacterium. Such a recombinant bacteriophage is designed to prime a subject's immune response and to kill the bacterium that it infects such that the 'prime and kill' bacteriophage provides two lines of protection against infectious disease.

The present invention relates to nucleic acid constructs capable of encoding antigenic peptides or polypeptides derived from multiple Human Papilloma Virus (HPV) early proteins, and to immunogenic compositions comprising such nucleic acid constructs and a pharmaceutically acceptable carrier. Such nucleic acid constructs and immunogenic compositions are useful in the treatment of persistent HPV infection and low-grade HPV lesions, particularly infections and lesions of human anogenital epithelial tissue, such as cervical epithelia.

Compositions and methods of treatment

Nucleotide constructs encoding antigenic peptides or polypeptides derived from multiple Human Papilloma Virus (HPV) early proteins, immunogenic compositions comprising such constructs and a pharmaceutically acceptable carrier, and uses thereof.

Viral antigens

HRV VP2 proteins useful as components of immunogenic compositions for the induction of cross-reactive cell-mediated immunity against human rhinovirus infection; nucleic acid constructs encoding such HRV VP2 proteins.
