Abstract
Bird's neck vaccine injector has fixed tubular guard around an injection needle. The guard is adapted to have a bird's neck pulled against it by pulling loose skin from the neck, and to have the pulled skin drawn over the projecting end of the guard and pressed against the guard so that the needle may be advanced to pierce the skin next to the projecting end of the guard and then inject vaccine into the cavity resulting from pull on the skin.
