Pharmaceutical form

Clinical particulars
Target species
Chickens and embryonated chicken eggs.
Indications for use specifying the target species
For the active immunisation of 18-day-old embryonated broiler hatching eggs or 1-day-old broiler chickens from hens vaccinated against IBD, to reduce mortality, clinical disease, weight loss and acute lesions of bursa of Fabricius associated with infection caused by very virulent Avian Infectious Bursal Disease (IBD) viruses.
The release of the vaccine virus from the complex (and therefore immunisation) is influenced by the natural decline of maternally derived antibodies (MDA), and has been found not to occur until MDA has reached relatively low levels.
The onset of clinical protection depends on the initial MDA level. In vaccinated broilers it is achieved within 1 day after the first signs of vaccine virus effect in the bursa of Fabricius.
Onset of immunity: between 21 and 32 days of age.
Duration of immunity: up to 42 days of age.
The virulent challenge tests conducted to support the claim were carried out on broilers having an MDA ELISA titre of 6,000 (1-day-old chicks).
Field trials carried out showed that vaccine virus replication in the bursa of Fabricius occurs in broilers having at hatch MDA titre levels of up to 14,000 ELISA units, but the protection of these birds was evaluated only based on serological data and histology of the bursa of Fabricius.
Contraindications
Do not use in eggs or in 1-day-old chickens coming from broiler breeder flocks not vaccinated according to an IBD immunisation program. (Refer to section Special precautions for use.)
Do not use in 1-day-old chickens hatched from eggs vaccinated in-ovo with Cevac Transmune.
Special warnings for each target species
Vaccinate healthy animals only.
Chicken embryos on the 18th day of incubation
In-ovo injection equipment must be used for in-ovo administration. Device(s) used for the reconstitution of the vaccine and for injection should be sterile and free from any residues of chemical disinfectant.
The device should be proven to safely and effectively deliver the appropriate 0.05 ml dose of the vaccine directly into the amniotic cavity or the embryo.
Before every in-ovo application the vaccination technique can be checked by use of a colour solution. The manufacturer's instructions of the device must be strictly followed. For cleaning of the instrument only products approved by the manufacturer may be used.
It is recommended to use 0.4-0.8 mm diameter needles, having length from 25-28 mm and perforation air pressure between 3.5 bar (50 psi) and 5 bar (72 psi).
1-day-old broiler chickens
Automatic syringe may be used for subcutaneous administration. Device(s) used for the reconstitution of the vaccine and for injection should be sterile and free from any residues of chemical disinfectant. The device should be proven to safely and effectively deliver the appropriate 0.1 ml dose of the vaccine. The instructions for use of this device should be strictly followed.
The vaccine must be inoculated under the skin of the neck of the 1-day-old broiler chickens. For cleaning of the automatic syringe, only products approved by the manufacturer may be used.
Residues of chemical disinfectant on the inner surface of devices and equipment used for reconstitution and application can destroy live virus and decrease the efficacy of the vaccine.
Special precautions for use
Special precautions for use in animals
Chicken embryos on the 18th day of incubation
The vaccine contains a strain of "intermediate-plus" virulence. In birds without MDA the inoculation of the vaccine results in significant immunosuppression and bursal damage. Therefore, it is not recommended to vaccinate eggs coming from flocks with MDA titre levels in 1-day-old chickens lower than 3,000 ELISA units.
Preliminary survey to be used to estimate MDA level of the chicks: 20, 1-day-old chicks originating from the same breeding flock should be sampled to measure their serological status to IBDV. The results of this sampling will indicate if the MDA level can be expected to be at least 3,000 ELISA units in the hatches of the following 4 weeks from this flock, and therefore that they are suitable for Cevac Transmune vaccination. According to results and needs, this survey has to be repeated at different times of the laying period.
The vaccine virus is excreted by vaccinated birds and can spread to susceptible birds and can be detected in unvaccinated birds 4-7 days later. To control the spread of the virus, the immunisation devices used for injection and the hatchery premises should be decontaminated after vaccination.
Chickens from vaccinated eggs should not be mixed with chickens from unvaccinated eggs.
Precautions should be taken regarding between-house spread. Whole site vaccination is recommended. Poultry houses should be decontaminated between batches of chickens.
Satisfactory protection can be achieved only in properly developed embryos at the 18th day of hatching. It is suggested to candle the eggs to be injected and discard eggs containing dead embryos.
1-day-old broiler chickens
The vaccine contains a strain of "intermediate-plus" virulence. In birds without MDA the inoculation of the vaccine results in significant immunosuppression and bursal damage. Therefore, it is not recommended to vaccinate chicks coming from flocks with 1-day-old MDA titre levels lower than 3,000 ELISA units.

Vaccinated chickens should not be mixed with unvaccinated chickens.
Precautions should be taken regarding between-house spread. Whole site vaccination is recommended. Poultry houses should be decontaminated between batches of chickens.
Satisfactory protection can be achieved only in healthy 1-day-old chickens.
Special precautions to be taken by the person administering the veterinary medicinal product to animal
Vaccinating personnel should wash and disinfect hands after use.
Adverse reactions (frequency and seriousness)
In vaccinated chickens, mild to moderate lymphocyte depletion is very commonly observed after the vaccine take, which is maximal at around 7 days after vaccine take. After 7 days, this depletion decreases and is followed by lymphocyte repopulation and regeneration of the bursa of Fabricius. In some cases, the replication of the vaccine strain may be prolonged (e.g. due to presence of very high maternal antibody titres in 1 day old chicks), and bursa scores can reach a maximum of 2.8 between 35 and 42 days of age, which does not affect the production parameters of the flock.
Use during pregnancy, lactation or lay
Do not use in eggs intended for hatching of layers or broiler breeders.
Do not use in 1-day-old chickens intended for layers or broiler breeders.
Interaction with other medicinal products and other forms of interaction
Safety and efficacy data are available which demonstrate that this vaccine can be mixed and administered with Vectormune ND by in-ovo or subcutaneous vaccination. The mixed products protect against Avian Infectious Bursal Disease (IBD) viruses, Newcastle disease virus and Marek’s disease virus. The safety and efficacy of the mixed vaccines are not different from those described for the vaccines administered separately. Read also the product information of Vectormune ND before use.
For the associated reconstitution of Vectormune ND and Cevac Transmune, the Cevac Solvent Poultry should be used.
In-ovo:
One single dose of 0.05 ml is injected into each 18-day-old embryonated broiler chicken egg.

Pharmacological particulars
Pharmacotherapeutic group: Immunologicals for Aves, live viral vaccines for domestic fowl. ATCvet code: QI01AD09
To stimulate active immunity against very virulent infectious bursal disease viruses in broiler chickens from hens vaccinated against IBD. The vaccine contains the live intermediate plus IBDV strain Winterfield 2512 bound to specific immunoglobulins. Both components form a complex which is administered through vaccination. The Winterfield 2512 vaccine virus, applied as a non-immune-complex vaccine results in a mean histological lesion score of 2.2 in the bursa of Fabricius, 28 days after vaccination (after oral vaccination of 1-day-old SPF chicken with 10 doses). The severity and duration of lesions is less significant following administration of the immune-complex vaccine.
