FOR ANIMAL TREATMENT ONLY

Do not vaccinate unhealthy birds.

Do not use in birds in lay or within 4 weeks before the onset of the laying period.

No information is available on the safety and efficacy from the concurrent use of this vaccine with any other, except Poulvac IB H120, administered to broilers at one-day of age, where this vaccine is authorised. It is therefore recommended that no other vaccine than this should be administered within 7 days before or after vaccination with Poulvac Bursine 2.

Do not mix with any other vaccine or immunological product.

Occasionally local and/or general reactions after administration of the vaccine can be observed. Reactions are usually transient.

Poulvac Bursine 2 is an invasive vaccine. It produces increasing bursal damage on bird to bird passage and this is accompanied by a degree of immunosuppression.

If you notice any serious effects or other effects not mentioned in this leaflet, please inform your veterinary surgeon.

The virus of the vaccine will spread to unvaccinated birds.

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.

Very virulent gumboro virus can breakthrough higher maternal antibody levels than vaccine virus.

Field infection is capable therefore of reaching birds before vaccine has a chance to take. Only use as part of a complete gumboro control programme involving hygiene, biosecurity, management, stocking density and disinfection, etc. Overwhelming levels of field virus may overcome vaccinal immunity.

If spray vaccination is applied, the user must at least protect their eyes with safety goggles and nose and mouth with a dust mask. A helmet with filtered air circulation may be used instead.

Withdrawal period: Zero days.
