For a full list of excipients, see section 6.1.


3. PHARMACEUTICAL FORM


Frozen virus-infected cell suspension and diluent for suspension for injection.


4. CLINICAL PARTICULARS


4.1 Target species


One day old chickens.


4.2 Indications for use, specifying the target species


For the active immunisation of chickens to reduce mortality and lesions caused by Marek’s Disease.

The onset of immunity is from 5 days of vaccination and the duration of immunity is not known but has been shown by challenge to be at least 4 weeks. Vaccine virus and antibodies to Marek’s disease virus have been shown to persist in vaccinated chickens for up to 2 years.


4.3 Contraindications


Do not use in sick chickens.


4.4 Special warnings


Vaccine virus spreads from bird to bird. In a study in highly susceptible Rhode Island Red birds, vaccine virus was shown to increase in virulence after ten passages.

Maternally derived antibody (MDA) can interfere with the development of active immunity. Where it is likely that recent field infection or vaccination of the parent flock has stimulated a high antibody titre and consequently a high level of MDA, the timing of the vaccination programme should be planned accordingly.


4.5 Special precautions for use, including special precautions to be taken by the person administering the medicinal product to animals


i. Special precautions for use in animals


Avoid stress in chickens before and after vaccination.
Avoid injection into or near joints and tendons.


ii. Special precautions to be taken by the person administering the veterinary medicinal product to animals


To avoid all possible risks of working with liquid nitrogen and/or explosion of glass ampoules, the following precautions must be taken.

Operator Warnings: Liquid nitrogen causes serious freeze burns and thawing ampoules may occasionally explode after removal from the liquid nitrogen. Operators must protect their face with a visor or goggles and hands with gloves, when handling liquid nitrogen containers and when thawing ampoules.

If liquid nitrogen is spilt and comes into contact with skin causing frost bite injuries immediately:

Warm affected area by immersion in water at 29 ± 1°C or by the use of body heat. Considerable pain will be experienced during warming but this is normal. Do not rub the affected area. Seek medical advice if full function and feeling are not rapidly restored.

After handling vaccine, operators should wash and disinfect their hands with an approved disinfectant.


4.6 Adverse reactions (frequency and seriousness)


No local or systemic reactions have been observed following the administration of the vaccine during safety studies. However, and in common with other immunological products, it is expected that local or systemic reactions may occur in a very small proportion of vaccinated birds.

4.7 Use during pregnancy, lactation or lay


Do not use in birds in lay.


4.8 Interaction with other medicinal products and other forms of interaction


Safety and efficacy data are available which demonstrate that this vaccine can be administered on the same day but not mixed with Poulvac IBH120, Poulvac NDW, Poulvac TRT and MD Vac. In the case of products administered parenterally, the products should be given at different sites.


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.


4.9 Amounts to be administered and administration route


One 0.2 ml dose per chicken.

The vaccine is to be administered by intramuscular injection in the thigh muscle or by subcutaneous injection in the neck.

Dilution of vaccine: Reconstitute each 1,000 doses with 200 ml of diluent. 2,000 dose ampoules should be reconstituted in 400 ml of diluent. Dilution should be done under sterile conditions with diluent at room temperature. An ampoule may occasionally explode after it has been taken out of liquid nitrogen so goggles should be worn. Take the ampoule of vaccine out of the container of liquid nitrogen into a bowl containing clean tepid water (temperature 27°C (80°F) and not higher than 37°C (98°F)). Thaw the vaccine concentrate by carefully turning the ampoule, then remove from the water and dry the ampoule. The thawed vaccine concentrate must be used immediately and cannot be refrozen.

All equipment used for vaccination should be sterile and contain no traces of detergents or disinfectants.

Break the ampoule and withdraw the total contents carefully into a 10 ml sterile disposable syringe, using an 18G x 1.5 inch (1.2 x 40 mm) or larger gauge needle. Slowly withdraw about 8 ml of diluent into the syringe. Turn the syringe 5-10 times to mix the contents well. Slowly transfer a small volume of the mixture into the empty vaccine ampoule in order to remove the last remnants of the vaccine and withdraw this small amount back into the syringe, and carefully transfer the entire contents of the syringe into the diluent bottle. Rotate the bottle about 10 times to mix the contents well. The bottle of diluent should be kept closed throughout the procedure.

The vaccine is now ready for use and should be used within 2 hours of reconstitution.

Administration: Poulvac Marek CVI may be administered either manually, preferably by using a multi-dose syringe dose and fitted with a 23G x 1 inch (0.60 x 25 mm) needle, or by a vaccination machine.

Administer the vaccine intramuscularly into the thigh muscle or subcutaneously in the neck.

NB During the vaccination procedure, rotate the bottle of reconstituted vaccine solution every 5 minutes to prevent the cells from sedimenting.


4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary


No local or systemic reactions have been observed after the administration of a tenfold overdose.


4.11 Withdrawal period(s)


Zero days.


5. IMMUNOLOGICAL PROPERTIES


The vaccine induces an active immunity against Marek’s Disease.
