Vaxxitek HVT+IBD
Active substance
ATC code
Species
Chickens.
Indications
For active immunisation of one-day-old chicks or 18 day-old embryonated chicken eggs:
- to prevent mortality and clinical signs and reduce lesions caused by MD virus (including very virulent MD virus), and
- to prevent mortality and clinical signs and lesions caused by IBD (also known as Gumboro disease) virus.
Onset of immunity: MD: 5 days post-hatch.
IBD: 14 days post-hatch (subcutaneous) or 28 days post-hatch (in ovo).
Duration of immunity:MD: A single vaccination is sufficient to provide protection for the entire risk period.
IBD: 10 weeks post-hatch.
Dose to be administered and administration route
Subcutaneous and in ovo use.
Preparation of the vaccine suspension:
• Wear protective gloves, spectacles and boots during the ampoule thawing and opening operations. The handling of liquid nitrogen should take place in a wellventilated area.
• Preparation of the vaccine shall be planned before the ampoules are taken from the liquid nitrogen. The exact amount of vaccine ampoules and amount of solvent needed shall be calculated first according to the table below provided as example:
|
Solvent bag |
Number of vaccine ampoules (subcutaneous use) |
Number of vaccine ampoules (in-ovo use) |
|
1 bag of 200 ml solvent |
1 ampoule (1000 doses) |
4 ampoules (1000 doses) or 2 ampoules (2000 doses) or 1 ampoule (4000 doses) |
|
1 bag of 400 ml solvent |
2 ampoules (1000 doses) or 1 ampoule (2000 doses) |
8 ampoules (1000 doses) or 4 ampoules (2000 doses) or 2 ampoules (4000 doses) |
|
1 bag of 800 ml solvent |
4 ampoules (1000 doses) or 2 ampoules (2000 doses) or 1 ampoule (4000 doses) |
16 ampoules (1000 doses) or 8 ampoules (2000 doses) or 4 ampoules (4000 doses) |
• Remove from the liquid nitrogen container only those ampoules, which are to be used immediately.
• Thaw the contents of the ampoules rapidly by gentle agitation in water at 25 °C─30 °C. The thawing process should not exceed 90 seconds. Proceed immediately to the next step.
• As soon as they are thawed, wipe the ampoules with a clean paper towel and then open them while holding them at arm’s length (in order to prevent injury if any ampoule breaks).
• Select an appropriately sized sterile syringe to withdraw the vaccine from all the ampoules that are thawed, and fit it with a needle of 18 gauge or larger.
• Tear the overpouch on the solvent bag, and then gently insert the syringe needle through the septum of one of the bag connecting tubes and withdraw 2 ml of solvent.
• Then draw up the complete contents of all the thawed ampoules into the syringe. Do this by slowly drawing up the contents from each ampoule by gently tilting the ampoule forward and inserting the needle with the bevel edge facing downwards towards the bottom of the ampoule. Continue until all the vaccine is drawn out of the ampoule.
• Transfer the syringe contents into the solvent bag (do not use the solvent if it is cloudy).
• Gently mix the vaccine in the solvent bag by moving the bag back and forth.
• It is important to rinse the ampoules and ampoule tips. To do this, draw up a small volume of the solvent containing the vaccine into the syringe. Then slowly fill the ampoule bodies and tips with it. Withdraw the content from the ampoule bodies and tips, and inject it back into the solvent bag.
• Repeat this rinsing operation once.
• Repeat the thawing, opening, transfer and rinsing operations for the appropriate number of ampoules to be diluted in the solvent bag.
• The vaccine is ready for use and should be mixed by gentle agitation and used immediately. During vaccination, gently swirl the bag frequently to ensure the vaccine remains homogenously mixed.
• The vaccine is a clear, red-orange coloured suspension for injection to be used within two hours. Do not freeze it under any circumstances. Do not re-use opened containers of vaccine.
Posology:
One single injection of 0.2 ml per one-day-old chick or 0.05 ml per 18-day-old embryonated chicken egg.
Method of administration:
The vaccine must be administered by subcutaneous injection in the neck or by in ovo injection.
Adverse reactions
None.

4. CLINICAL PARTICULARS
4.1 Target species
Day-old chickens and 18 days embryonated eggs.
4.2 Indications for use, specifying the target species
For active immunisation of chickens:
• To prevent mortality and to reduce clinical signs and lesions of Infectious Bursal disease.
The onset of protection is from 2 weeks and the protection extends to 9 weeks.
• To reduce mortality, clinical signs and lesions of Marek’s disease. The onset of protection is from 4 days. A single vaccination is sufficient to provide protection during the risk period.
4.3 Contraindications
Do not use in birds in lay and breeding birds.
4.4 Special warnings for each target species
Vaccinate only healthy birds.
4.5 Special precautions for use
Special precautions for use in animals
Apply the usual aseptic precautions to all administration procedures.
As a live vaccine, the vaccine strain is excreted from vaccinated birds and may spread to turkeys. Safety and reversion to virulence trials have shown that the strain is safe for turkeys. However, precautionary measures have to be followed in order to avoid direct or indirect contact between vaccinated chickens and turkeys.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
Wear protective gloves and spectacles during the ampoule thawing and opening operations.
Open ampoules holding them at arm’s length in order to prevent any risk of injury should an ampoule break.
4.6 Adverse reactions (frequency and seriousness)
None known.
4.7 Use during pregnancy, lactation or lay
Do not use in breeding birds and birds in lay.
4.8 Interaction with other medicinal products and other forms of interaction
For subcutaneous route:
Safety and efficacy data are available which demonstrate that this vaccine can be mixed with Boehringer Ingelheim attenuated vaccines against Marek’s disease containing either Rispens (CVI988) strain or RN1250 strain. Chickens with maternally derived antibodies against MD, when vaccinated with the mixed products, may have a delayed onset of immunity against infectious bursal disease.
Safety and efficacy data are available which demonstrate that this vaccine can be administered on the same day but not mixed with Boehringer Ingelheim attenuated vaccines against Newcastle disease and Infectious bronchitis.
No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product except the products mentioned above. A decision to use this vaccine before or after any other veterinary medicinal product therefore needs to be made on a case by case basis.
For in ovo route:
In the absence of specific studies, no other veterinary medicinal product should be administered concurrently with the product.
4.9 Amounts to be administered and administration route
Reconstitution of the vaccine
• Wear protective gloves and spectacles during the ampoule thawing and opening operations.
• Remove from the liquid nitrogen container only those ampoules which are to be used immediately. When this product is mixed with Marek’s disease vaccine containing either Rispens (CVI988) strain or RN1250 strain, both should be diluted in the same solvent bag.
• Thaw the contents of the ampoules rapidly by agitation in water at 25°C-30°C. Proceed immediately to next step.
• As soon as they are thawed, open ampoules holding them at arm’s length in order to prevent any risk of injury should an ampoule break.
• Once the ampoule is opened, draw up the contents into a 5 ml sterile syringe.
• Transfer the suspension into the diluent (Do not use if cloudy).
• Draw up 2 ml of the contents of the diluent into the syringe.
• Rinse the ampoule with these 2 ml and then transfer the rinsing liquid into the diluent. Repeat the rinsing operation once or twice.
• Repeat the thawing, opening, transfer and rinsing operations for the appropriate number of ampoules to be reconstituted in the diluent; either 1 ampoule of 1,000 doses of vaccine per 200 ml of diluent (or 1 ampoule of 2,000 doses of vaccine per 400 ml of diluent) for subcutaneous administration, or 4 ampoules of 1,000 doses of vaccine per 200 ml of diluent (or 4 ampoules of 2,000 doses of vaccines per 400 ml of diluent) for in ovo administration.
• The diluted vaccine prepared as described is mixed by gentle agitation so as to be ready for use. It should be used immediately after the preparation (all of the diluted vaccine should be used up within one hour). This is why the vaccine suspension should only be prepared as and when required.
