Vaccinate healthy animals only.
Do not use in birds in lay and within 4 weeks before the start of the laying period.
No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product, except for the concurrent use with Poulvac IB H120, administered to broilers at one-day of age. A decision to use this vaccine before or after any other veterinary medicinal product, besides Poulvac IB H120, therefore needs to be made on a case by case basis.
Do not mix with any other veterinary medicinal product.
Adverse Reactions
Local and/or general reactions after administration of the vaccine can be observed very rarely. Reactions are usually transient.
Poulvac Bursine 2 produces increasing bursal damage on bird to bird passage and this is accompanied by a degree of immunosuppression.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals treated displaying adverse reaction(s))
- common (more than 1 but less than 10 animals in 100 animals treated)
- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)
- rare (more than 1 but less than 10 animals in 10,000 animals treated)
- very rare (less than 1 animal in 10,000 animals treated, including isolated reports).
If you notice any serious effects, even those not already listed above or you think that the medicine has not worked, please inform your veterinary surgeon.
Special warnings
Maternally-derived antibodies (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 Infectious Bursal Disease 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 Infectious Bursal Disease control programme involving hygiene, biosecurity, management, stocking density and disinfection, etc. Overwhelming levels of field virus may overcome vaccinal immunity.
The vaccine virus can spread to in contact birds.
Care should be taken to ensure that the vaccine virus does not spread to unvaccinated birds. It is recommended to vaccinate all chickens on a site at the same time. Cleaning and disinfection of the premises is advisable between flocks.
Withdrawal period
Zero days.
User warning
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. It is recommended to wash and disinfect hands and equipment after vaccinating.
