    Can you give the vaccine to chickens who might have been exposed to Marek's to prevent it???

    No.
    Marek's vaccine has to be administered invitro or as day old chicks. Every day that passes, the vaccine is less effective.

    The reason is, it is in a race with that in the environment. After exposure, it will offer no protection.
