Modified Marek's disease virus, and vaccines made therefrom

The present invention provides an effective vaccine for Marek's disease, which may be prepared using a recombinant Marek's Disease Virus (MDV), strain CVI988, having been transformed with a foreign DNA construct that includes a long terminal repeat sequence of a reticuloendotheliosis virus. This safe viral agent elicits a highly protective immune response in a chicken against virulent MDV challenge without causing a significant degree of pathogenicity. Suitable formulations of the vaccine for use in chickens include an effective immunization dosage of this novel viral agent, along with a pharmaceutically acceptable carrier or diluent.

Vaccine compositions of herpesvirus envelope protein combinations to induce immune response

Provided are antigenic compositions and uses thereof that include at least two human herpesvirus (HHV) polypeptides involved in mediating HHV binding, fusion, and entry into host cells, such as gp350, gH, gL, and gB, or nucleic acids encoding the polypeptides. The two HHV polypeptides comprise any combination of: a gB polypeptide; a gp350 polypeptide; a gL polypeptide; and a gH polypeptide, and optionally any one or more of the following polypeptides: gp42, gM, gN, gl, gC, gE, gD, ORF68, BMRF-2, BDLF2, UL128, UL130, UL131A, and gpK8.1. Also disclosed are methods of inducing an immune response or treating or preventing an HHV infection in a subject by administering to the subject at least two of the HHV polypeptides or nucleic acid(s) encoding the same. Methods of passively transferring immunity using high-titer anti-HHV antibodies or immune cells are also disclosed.

VACCINE DELIVERY METHOD

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.
