AVI Pox

Chickens should be vaccinated with AVI POX between 4 and 16 weeks of age. Birds should be vaccinated no later than 4 weeks before the onset of laying. Re-vaccination is not required following proper initial vaccination. Wing-web administration Fill the vaccine vial with diluent till ¾ of the total volume to dissolve the lyophilised vaccine. Pour and dilute the vaccine suspension into the diluent remaining into the diluent bottle.

The vaccine is applied to the web of the wing using the two-pronged applicator.

To apply the vaccine, dip the applicator into the prepared vaccine and stab into the webbed portion of the wing from the underside of the wing. Avoid stabbing through feathers, as they would wipe off the vaccine. The applicator is designed to carry the proper amount of vaccine in the grooves of the needles. The needles should be touched briefly to the inner lip of the bottle before withdrawing. This avoids waste of vaccine that may drop from the needles. Re-dip the applicator after each application. At 7-10 days after vaccination one should observe at the point of administration, swelling of the skin with scab formation: this is the sign of vaccine “takes”. A good reaction is a good indicator of successful immunization. Post-vaccination “takes” does not occur in previously immunized birds or in case of improper application.
