Nobilis Marexine CA 126 Data Sheet

Presentation 

Nobilis® Marexine CA126 consists of a suspension of living cultured avian cells containing at least 3.0 log₁₀ pfu of attenuated isolate of Turkey Herpesvirus (Strain FC126).

The vaccine is supplied in frozen ampoules held in metal canes stored in a liquid nitrogen canister. 

Uses 

For the active immunisation of chickens to prevent mortality, clinical signs and/or lesions of Marek's Disease.

Dosage and administration 

Reconstitution: 

Reconstitute the vaccine in Nobilis Diluent CA (Vm 01708/4270), allowing 1000 doses of vaccine to each 200 ml. Prior to reconstitution the vaccine is thawed.   Great care should be taken - see operator warnings. Remove one ampoule from the cane and immediately replace the cane in the liquid nitrogen canister.   Thaw the contents of the ampoule rapidly by immersing in water at room temperature.   Do not thaw in hot or ice-cold water.   Dry the ampoule and shake to disperse contents.   After thawing open the ampoule immediately and draw the entire contents into a sterile 5 - 10 ml syringe using an 18 gauge needle to avoid rupturing the cells.   Insert the needle through the stopper of the diluent vial (which should be at room temperature) and draw up slowly a portion of the diluent.   Add the contents of the syringe to the remaining diluent.   It is important that this is done slowly, allowing the vaccine to run down the side of the bottle.   Gently shake the bottle as the vaccine is being mixed.   Withdraw a portion of the vaccine and use to rinse the ampoule.    Inject the washing back into the diluent vial.    The reconstituted vaccine must be handled gently and administered through wide gauge needles to avoid rupturing the cells.   Fill the sterilised repeating syringe/ automatic vaccinator according to the manufacturer’s instructions.   The vial of reconstituted vaccine should be kept in an ice bath when not being used.  

Administration

Administer by a single injection of 0.2 ml subcutaneously in the neck or intramuscularly in the leg, after reconstitution in the diluent provided. Injection should be made using an approved repeating syringe or automatic vaccinator. A needle of 20g x 1/2" should be used to inject the birds.     Equipment used for vaccination should be sterile and contain no traces of detergents or disinfectants.

The recommended age for injection is one‑day but Nobilis Marexine CA126 can be effectively administered to birds up to three weeks of age.

Care should be taken that the vaccine virus does not spread to unvaccinated birds.

Contra-indications, warnings, etc. 

1.   Only healthy birds should be vaccinated. Sick or weak birds will not develop adequate immunity following vaccination.

2.   Do not co-administer with vaccines other than Nobilis Rismavac^® .

3.   Do not mix with unapproved products.

Operator warning

The operator should be aware of the general precautions to be taken when handling liquid nitrogen and/or material at very low temperature. Ampoules may explode on sudden temperature changes, therefore the operator should protect himself with gloves and a visor.   When removing an ampoule from a cane hold the palm of a gloved hand away from body and face.   After handling vaccine operators should wash and disinfect hands with an approved disinfectant.

First aid treatment of frost bite injuries:Warm affected part by immersion in water at 29 + 1ºC or use body heat. There will be considerable pain during warming, but this is normal. Do not rub affected area, seek medical advice.

Withdrawal period: 

Zero days

FOR ANIMAL TREATMENT ONLY.  KEEP OUT OF REACH AND SIGHT OF CHILDREN.

Further information 

A good immune response is reliant on the reaction of an immunogenic agent and a fully competent immune system. Immunogenicity of the vaccine antigen will be reduced by poor storage or inappropriate administration. Immunocompetence of the animal may be comprised by a variety of factors including poor health, nutritional status, genetic factors, concurrent drug therapy and stress. Under certain conditions, for example extreme disease pressure and variant challenge, fully immune birds may succumb to disease. Therefore, successful vaccination may not be synonymous with full protection in the face of a disease challenge.
