“The vaccine candidates have been thoroughly verified by a series of in-house and
external tests and are exactly what we want them to be. A pilot trial to test both
candidates in a bird flu challenge trial has been designed and negotiations are underway
to secure a trial facility and starting date.”
The two vaccine candidates differ as the commercial requirements for broilers and
breeders or layers vary. The primary aim for a commercial Bird Flu vaccine for broilers is
to provide immunity early in a bird’s life but the protection need only be short term as
broiler birds typically reach market weight by 42-49 days of age. Layer birds and birds
used for breeding stock for the broiler market require longer lasting immunity. The
vaccine designed for layers and breeders uses two antigens (rather than the single
antigen used in the broiler vaccine) to elicit both antibody and cell mediated immunity.
