Bluetongue vaccine

Bluetongue virus vaccine: conventional to modern approach Bluetongue (BT) is an economically important, infectious and non-contagious disease of ruminant animals. BT disease is caused by bluetongue virus (BTV) of the genus Orbivirus (the family Reoviridae). BTV is transmitted by certain species of biting midges of the genus Culicoides Active Ingredient (s): Contains bluetongue vaccine modified live virus, type 10. Penicillin and streptomycin are added as preservatives. The advantages of the tissue culture technique for viral vaccine production are well understood and widely accepted in medical circles § 113.303 Bluetongue Vaccine. Bluetongue Vaccine shall be prepared from virus-bearing cell culture fluids. Only Master Seed which has been established as pure, safe, and immunogenic shall be used for preparing the seeds for vaccine production. All serials of vaccine shall be prepared from the first through the tenth passage from the Master Seed Since there is no curative treatment for BTV-infected animals, prophylactic immunization of susceptible species remains the most effective and practical control measure against bluetongue in endemic regions. In the U.S., the only vaccine approved for national use is a monovalent attenuated modified-live vaccine against serotype 10

Isolation of 8 serotypes of bluetongue virus (BTV) in Australia has led to widespread debate on how to prepare for an outbreak of bluetongue disease and the type of vaccine best suited to control bluetongue in Australia. This article describes the vaccine options under consideration by research work At present the only vaccines used against bluetongue (BT) disease are live-attenuated virus vaccines. Since viruses with RNA genomes such as BT virus (BTV) have a high frequency of mutations, live virus vaccines could have breakthroughs (vaccine failures) and mutate into virulent strains

Bluetongue virus proteins derived from baculovirus expression vectors have been administered in different combinations to sheep, a vertebrate host susceptible to bluetongue virus, and the neutralizing antibody responses were measured. Vaccinated sheep were subsequently challenged, and the indices of clinical reaction were calculated received a bluetongue virus-contaminated vaccine. Transplacental transmission has been demonstrated in dogs, at least for serotype 11. Disinfection Disinfectants reported to be effective against bluetongue virus include sodium hypochlorite and 3% sodium hydroxide. Sodium hypochlorite, iodine (potassiu Bluetongue virus (BTV) is an orbivirus that infects both domestic and wild ruminants and is transmitted by Culicoides spp. biting midges (Price and Hardy 1954, Borden et al. 1971, Matthews 1982). Among the arboviruses transmitted by Culicoides, BTV has the greatest economic impact (Bath 1989), with losses attributed to effects on animal health. Bluetongue vaccines for sheep and cattle are now available across Britain, with supplies approved for use in vet practices. There is a high risk of an outbreak of Bluetongue (BTV-8) towards the end.. Bluetongue virus (BTV) causes the hemorrhagic disease bluetongue (BT) in ruminants. The best way to control outbreaks is vaccination. Currently, conventionally modified-live and inactivated vaccines are commercially available, which have been successfully used to control BT, but nonetheless have their specific shortcomings

Vaccines for Prevention of Bluetongue and Epizootic Hemorrhagic Disease in Livestock: A North American Perspective D. Scott McVey1 and N. James MacLachlan2 Abstract Bluetongue (BT) and epizootic hemorrhagic disease (EHD) are noncontagious, insect-transmitted diseases of domestic and wild ruminants caused by related but distin ct viruses After the incursion of bluetongue virus (BTV) into European Mediterranean countries in 1998, vaccination was used in an effort to minimize direct economic losses to animal production, reduce virus circulation and allow safe movements of animals from endemic areas What is bluetongue and what causes it? Bluetongue is a non-contagious, viral disease spread by biting insects. It affects species of ruminants, particularly sheep. Bluetongue causes Vaccines are available for animals deemed to be at high risk of contracting bluetongue, however, these vaccines are not without risk

Bluetongue Vaccine shall be prepared from virus-bearing cell culture fluids. Only Master Seed which has been established as pure, safe, and immunogenic shall be used for preparing the seeds for vaccine production. All serials of vaccine shall be prepared from the first through the tenth passage from the Master Seed Bluetongue (BT) is a haemorrhagic disease of wild and domestic ruminants with a huge economic worldwide impact on livestock. The disease is caused by BT-virus transmitted by Culicoides biting midges and disease control without vaccination is hardly possible. Vaccination is the most feasible and cost-effective way to minimize economic losses Bluetongue virus is a substantial health risk to sheep and other ruminants. Livestock can be protected by vaccination, but as described in this Review, current vaccines can have severe drawbacks. Prospects of Next-Generation Vaccines for Bluetongue. Bluetongue (BT) is a haemorrhagic disease of wild and domestic ruminants with a huge economic worldwide impact on livestock. The disease is caused by BT-virus transmitted by Culicoides biting midges and disease control without vaccination is hardly possible

REVIEWS Prospects for improved bluetongue vaccines Polly Roy, Mark Boyce and Robert Noad Abstract | Bluetongue has been recognized as a viral disease of livestock for more than 100 years. Repeated incursions of Bluetongue into Europe since 1998 have been particularly devastating for highly sensitive European fine-wool sheep breeds, and have. - For bluetongue vaccines (authorised under exception al circumstances or standard authorisations) the following fee reductions will apply: 100% of the annual fee for a ny bluetongue vaccine that has not been marketed within the EU/EEA during the year and 0% for any bluetongue vaccine that has been marketed wi thin the EU/EEA during the year The control of bluetongue is different in areas where the disease is not endemic. During an outbreak, when one or a limited number of serotypes may be involved, vaccination strategy depends on the serotype(s) causing infection. Use of vaccine strains other than the one(s) causing infection affords little or no protection and is not recommended

Bluetongue (BT) is a serious hemorrhagic disease of ruminants caused by bluetongue virus (BTV). Inactive BTV vaccines have been successful in field trials in some areas, and inactivated vaccines are considered safer. However, information about the effect of the viral antigen level on the serological response and efficiency of the inactive BTV-16 vaccine is lacking Bluetongue is an arthropod-borne viral disease of ruminants. Bluetongue virus (BTV) is spread by insect vectors, Culicoides midges, feeding on viraemic animals. All ruminant species are susceptible; however bluetongue is primarily a disease of sheep.
