With newly hatched chicks it takes two weeks after the shot for the vaccine to become effective. That means that for the first two weeks they can't be with older birds who might carry the virus.
Conversely, if the hens get shots and the chicks hatch before the hen is protected, they need to be separated until the hen is in the clear.
As I said, with babies it's two weeks. Maybe someone knows if the absorption rate in a hen is different.
