    摘要: Viruses having weakened ability to establish and/or maintain latency and their use as live vaccines are described. The vaccines have one or more alterations in genes that provide continued virus replication but that inhibit latency. The vaccine materials and methods for their construction are exemplified with the varicella zoster virus. Deletion of a significant portion from both copies of the varicella zoster gene ORF63 was shown to inhibit establishment of a latent infection from a live vaccine form of the virus. Insertion of an additional ORF62 gene which is partially truncated with the ORF63 deletion inhibited establishment of latency and allowed normal growth of the virus. Other desirable viral antigen encoding sequence(s) and/or cytokine genes advantageously may replace deleted genetic material to enhance a desired immunological response. Aspects of the discovery pertain to live vaccines of other viruses, and can provide a variety of vaccines having greater safety.

    摘要: This invention relates to Equine Herpes Viruses (EHV) wherein the protein gM is essentially absent or modified and non-functional with respect to its immunomodulatory capacity. Further aspects of the invention relate to nucleic acids coding said viruses, pharmaceutical compositions comprising these viruses or nucleic acids and uses thereof. The invention also relates to methods for improving the immune response induced by an EHV vaccine against wild type EHV infections, methods for the prophylaxis and treatment of EHV infections and methods for distinguishing wild type EHV infected animals from animals treated with EHV's according to the invention.

    摘要: The invention provides an inactivated varicella zoster virus (VZV), and compositions and vaccines comprising said inactivated VZV, wherein the infectivity of the VZV is undetectable and wherein the inactivated VZV induces an immune response against VZV when administered to a patient. In embodiments of the compositions described herein, the VZV is inactivated with gamma radiation. The invention also provides a method of preparing an inactivated VZV vaccine, the method comprising gamma irradiating a sample comprising a VZV using from about 5 kGy to about 50 kGy of gamma radiation. Also provided by the invention herein is a method of treatment of or immunization against HZ or other disease associated with the reactivation of VZV, the method comprising administering to a subject a vaccine or pharmaceutical composition comprising a therapeutically effective amount of an inactivated VZV and a pharmaceutically acceptable carrier, wherein the VZV is inactivated by gamma irradiation.
