What is Vaxxitek HVT+IBD?
Vaxxitek HVT+IBD is a recombinant vaccine intended for use against Infectious Bursal Disease (also known as Gumboro Disease) and Marek’s Disease in chickens. It is presented as a frozen suspension to be reconstituted with diluent and injected into chickens and into eggs where chicks are developing.
What is Vaxxitek HVT+IBD used for?
Vaxxitek HVT+IBD is used to prevent the deaths of chickens and to reduce clinical signs and effects of Infectious Bursal disease which is a disease which damages the immune system of chickens. Vaxxitek HVT+IBD is also used to reduce mortality, clinical signs and effects of Marek's disease, a herpes virus infection of chickens.
How does Vaxxitek HVT+IBD work?
Vaxxitek HVT + IBD contains vaccine strains which induce an active immunity and a serological response (detected antibodies) against the two diseases. The product appears to show no interference with antibodies derived from the mother bird and can be safely administered to
How has Vaxxitek HVT+IBD been studied?

What benefit has Vaxxitek HVT+IBD shown during the studies?
The studies demonstrated that Vaxxitek HVT+IBD is effective in the active immunisation of chickens and chicks in the egg against Infectious Bursal disease. The onset of protection is from 2 weeks onwards and the protection extends to 9 weeks. The vaccine is also effective against Marek’s disease. The onset of protection is from 4 days onwards. A single vaccination is sufficient to provide protection during the risk period.
What is the risk associated with Vaxxitek HVT+IBD?
Only healthy birds should be vaccinated and the product should not be used in birds in lay and breeding birds. No information is available on the safety and efficacy from the concurrent use with any other vaccine, except Merial attenuated vaccines against Marek’s disease, Newcastle disease and Infectious bronchitis. It is therefore recommended that no other vaccine than these should be administered within 14 days after vaccination with the product. In the absence of specific studies, no other vaccine should be administered at the same time when the product is injected into eggs.
What are the precautions for the person who gives the medicine or comes into contact with the animal?
As the product is stored in a tank under liquid nitrogen, particular instructions for reconstitution of the vaccine are provided in the product information module of the EPAR.
What is the time to allow before the animal can be slaughtered and the meat used for human consumption (withdrawal period)?
Why has Vaxxitek HVT+IBD been approved?
The Committee for Medicinal Products for Veterinary Use (CVMP) concluded that the benefits of Vaxxitek HVT+IBD exceed the risks of its use in chickens and recommended that Vaxxitek HVT+IBD be given a marketing authorisation. The
