For animal treatment only.
Do not use in sick chickens.
Can be used before the onset of lay in chickens intended for breeding. The safety of the veterinary medicinal product has been demonstrated when administered during lay.
Care should be taken in the planning and implementation of vaccination programmes as vaccine virus may spread from vaccinates to non vaccinated chickens. It is recommended that all chickens on a site be vaccinated with this product.
Safety and efficacy data are available which demonstrate that this vaccine, when administered by the spray route to maternal antibody positive chicks, can be administered on the same day as Poulvac NDW and Poulvac SHS. 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 decided on a case by case basis.
Do not use with any other veterinary medicinal product.
It is recommended to spray vaccinate in a sealed cabinet. Alternately, the eyes and face of vaccination staff should be protected by a full face mask approved to BS2091 (e.g. a Siebe-Gorman vista type) and eye goggles should be worn. A helmet with filtered air circulation may be used instead of goggles and mask.
On completion, operators should wash and disinfect hands in an Approved Disinfectant.
Adverse Reactions
A mild vaccination reaction can be observed in the form of transient, slight respiratory symptoms such as occasional sneezing and coughing. No harmful clinical effects have been observed. Tracheal histopathology revealed very low scores in the post vaccination period.
A ten-fold overdose administered by eye drop to day-old SPF chicks, observed over 21 days, elicited no effects more severe than those observed with a single dose.
Special Warnings
It is accepted that spray administration offers benefits over water administration in terms of ease of application and percentage of birds vaccinated. Nevertheless, greater secondary problems may result under certain management conditions. Spray vaccination should not be used if intercurrent infection is suspected. It is important to consult your veterinary adviser or Zoetis technical staff before using the spray technique.
Efficacy against infectious bronchitis caused by the 4/91 (793B) UK variant IB strain has not been demonstrated.
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.
Withdrawal period
Zero days.
