Is there any concern when giving varicella vaccine to a child who lives with a susceptible pregnant woman or an immunocompromised individual?

ACIP recommends varicella vaccine for healthy household contacts of pregnant people and immunosuppressed people. Although there may be a small risk of transmission of varicella vaccine virus to household contacts, the risk is much greater that the susceptible child will be infected with wild-type varicella, which could present a more serious threat to household contacts.
