An engineered Newcastle Disease Virus (NDV) vector is provided. In particular, the present disclosure provides methods of treating or preventing a disease such as cancer, or an infectious disease, or methods for eliciting an immune response, with the engineered NDV vector. The engineered NDV vector provided herein is useful as an immunogenic composition, an oncolytic agent, or a vaccine.

The present invention describes a recombinant herpesvirus of turkeys (rHVT) that can be used as a vector vaccine for poultry against infection and disease from multiple poultry pathogens. Specifically the rHVT expresses an infectious bursal disease virus (IBDV) viral protein 2 (VP2) gene and a Newcastle disease virus (NDV) fusion (F) protein gene from a first and a second expression cassette inserted in the unique small (Us) region, and expresses an avian influenza vims (AIV) haemagglutinin (HA) gene from a third expression cassette inserted in the unique long (UL) region of the genome of said rHVT either between the UL40 and UL41 genes, or between the UL44 and UL45 genes. This rHVT can be used to vaccinate poultry against MDV, IBDV, NDV and AIV.

A vaccine delivery method is presented that includes a composition including as one component a slurry matrix that is a liquid at room temperature and a gel at physiological pH, physiological salt concentrations and/or physiological temperatures and as a second component one or more antigens. Also included are methods of inducing an immune response in a subject and vaccinating a subject by administering such compositions.
