The present invention relates to a virus-like particle for preventing or treating toxoplasmosis, comprising influenza virus matrix protein 1; and surface antigen proteins comprising an inner membrane complex, Rhoptry protein 18 and Microneme protein 8 derived from Toxoplasma gondii, and a pharmaceutical composition comprising the same.

In certain embodiments, the present invention provides isolated replication defective non-integrating segmented viruses comprising a genome where at least one of the viral segments comprises a heterologous nucleotide sequence comprising a nucleotide segment that encodes an effector protein. Also provided are methods of using these viruses.

The present invention relates to a virus-like particle for preventing or treating toxoplasmosis, comprising influenza virus matrix protein 1; and surface antigen proteins comprising an inner membrane complex, Rhoptry protein 18 and Microneme protein 8 derived from Toxoplasma gondii, and a pharmaceutical composition comprising the same.

Provided are specific immunotherapy methods for allergies in which one or more peptides specific for the allergy being treated is administered to the patient incorporated within a virosome and in the presence of a Toll-like receptor (TLR) agonist.

The present invention provides a composition for multiplex diagnosis of Toxoplasma gondii and/or influenza virus, comprising virus-like particles (VLPs) that comprise a T. gondii surface antigen protein, and VLPs that comprise an influenza virus M1 protein. In one embodiment, the VLPs comprise at least one protein from the group consisting of TgAMA1 VLP, TROP4 VLP and TgROP18. The composition for multiplex diagnosis can react, with high sensitivity and specificity, to biological samples isolated from individuals infected with T. gondii and individuals infected with Influenza virus. Therefore, the composition for multiplex diagnosis can be used in a kit for multiplex diagnosis of toxoplasmosis and/or Influenza virus.

The present invention provides a vaccine composition comprising: (i) an adjuvant; and (ii) at least one fusion peptide conjugated to a carrier protein, wherein the carrier protein is the diphtheria toxin variant CRM-197 (GenBank Accession No. and wherein the at least one fusion peptide comprises two or more non- contiguous B cell epitopes of Her2/neu selected from the group consisting of SEQ ID Nos:1-7 and 15-60 and amino acid sequences that have at least 85% identity to any of the foregoing. The present invention also extends to pharmaceutical compositions and methods of using the vaccine and/or pharmaceutical compositions, as herein described, for the treatment or prevention of a cancer characterised by the expression or over-expression of Her2/neu in a patient in need thereof.
