INNOVAX® ND Vaccine
EN
HVT/NDV-F
No
Innovax®-ND, a recombinant vaccine that helps aid in the protection of Newcastle and Marek’s diseases in chickens. Innovax-ND utilizes the herpesvirus of turkey (HVT) to carry Newcastle disease (ND) antigens, which induce immunity against ND.  HVT also protects chickens against Marek’s disease, which is caused by a herpesvirus and results in tumors, high mortality and immunosuppression.

The term “Recipient organism” refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas “Parental organisms” refers to those that were involved in cross breeding or cell fusion.
PB1 strain: non-virulent , non pathogenic strain of the HTV virus, which is used as a vaccine for over two decades.

    Protein coding sequence | Production of medical or pharmaceutical compounds (human or animal) (Vaccines)
The INNOVAX® ND Vaccine is a recombinant HVT strain that contains a gene that codes for the fusion protein (F-protein) of the Newcastle Disease virus, directed by promoter derived from the Rous sarcoma virus long terminal repeat sequence (LTR).

The gene was integrated into the host genome through homologous recombination as follows:

1. The protein F coding sequence was obtained through cDNA synthesis of genomic NDV, clone 30, RNA that was harvested and purified from infected embryonated eggs.

2. The F-protein coding cDNA was isolated and cloned into the HVT recombination vector  pVECO4, which also contains the Rous sarcoma virus LTR promoter, resulting in the pNDVO4 plasmid.

3. pNDVO4 plasmid DNA and HVT were co-transformed into chicken embryo fibroblasts and incubated under conditions that favour homologous recombination.

4. Selection of the recombinant virus was conducted by immunofluorescence, to detect F protein expression. The resulting strain was named HVT/NDV-F. Sequences of plasmids or markers were not detected in the recombinant virus.

Additional Information
With the use of the Innovax ND vaccine, immunity against Newcastle Disease starts at two weeks of age and lasts for at least of 60 weeks after one single dose of the vaccine. For Marek’s Disease, immunity starts at the fifth day of age and the vaccine lastes for the whole period of risk.

The vaccine is administered to chicken embryonic eggs at 18 days of incubation through the in ovo route, or to one day chicks through subcutaneous injections.
