The only way to get the ILT vaccine is through a vet. If you have a local vet you use they can order the vaccine for you. You want the LT Ivax vaccine that you administer via a drop in the eye. One vial of vaccine treats 1000 birds but once mixed the vaccine is only good for 2 hours. If you don't have a local vet that will order it I have contact info for a vet in Guelph that will ship the vaccine, or at least he use to ship it.
