Abstract of the Disclosure Avian diseases, particularly those which threaten birds early in life, are controlled by embryonal vaccination during the final quarter of incubation. The site of inoculation may be either into the amnion, to include the amniotic fluid and the embryo itself, or else into the yolk sac. Protection afforded to chicks inoculated prehatch is four times or more than that of chicks inoculated post hatch.
