In countries with high TB prevalence, WHO recommends a policy of routine BCG immunization for all neonates except those who are known to be HIV-infected (Ref.)
BCG vaccination should not be given to (i) infants and children known to be HIV-infected or (i) children known to have other immunodeficiencies.
In situations where infants have been exposed to smear-positive PTB shortly after birth, BCG vaccination should be delayed until completion of six months of isoniazid preventive therapy (IPT).
