Vaxxitek HVT + IBD is a live vaccine based on the use of a recombinant turkey Herpesvirus (HVT) expressing the VP2 gene of the Infectious Bursal Disease (Gumboro disease) Virus (IBDV).

This vaccine contains a live strain of serotype 3 vectored virus that has been shown to aid in the prevention of Bursal disease and Marek's disease.

Notes regarding the genetic elements introduced or modified in this LMO
Vaxxitek HVT + IBD vaccine is a live recombinant vaccine against Gumboro disease (or infectious bursal disease) and Marek's disease in chickens. It is a frozen vaccine to be diluted with an aqueous diluent. The active ingredient is the production-cell associated vHVT013-69 virus vaccine strain, a recombinant turkey Herpesvirus (HVT) expressing the VP2 coding sequence of Infectious Bursal Disease Virus (IBDV). The parental strain of Vaxxitek HVT + IBD (named FC-126) belongs to the serotype 3 of Marek's disease and is widely used in classical vaccination against Marek's disease. HVT strains are apathogenic in all species, and do not replicate in mammalian cells. The inserted sequence corresponds to the sequence coding for the VP2 protein of Infectious Bursal Disease Virus (IBDV). It has been cloned from 52/70 Faragher strain. The VP2 protein is the only protein of IBDV that induces protection against Gumboro disease.
