Introduction
Newborns should avoid receiving the BCG vaccine if they are allergic to the vaccine components, have immunodeficiency or impaired immune function, are undergoing immunotherapy, or suffer from acute or chronic diseases or are in an active phase of illness. Additionally, BCG vaccination should be avoided in newborns with neurological disorders, eczema, or a birth weight less than 2500g, to prevent potential adverse reactions.
Specific contraindications for BCG vaccination in newborns are as follows:
1. Vaccination should be avoided if the newborn is allergic to any component of the BCG vaccine.
2. Vaccination should also be avoided if the newborn has immunodeficiency, impaired immune function, or is currently receiving immunosuppressive therapy.
3. Vaccination should be avoided in cases of severe chronic illness, acute illness, during an exacerbation of chronic disease, or if the infant has a fever.
4. BCG vaccination is contraindicated in newborns with encephalopathy, uncontrolled epilepsy, or other progressive neurological disorders.
5. If the newborn has severe eczema or other skin diseases, vaccination should be postponed until full recovery to prevent worsening of symptoms.
6. Vaccination should be avoided if the newborn's birth weight is less than 2500g.
The BCG vaccine is used to prevent tuberculosis in children, especially tuberculous meningitis and acute hematogenous disseminated tuberculosis. Newborns generally receive the vaccine via intradermal injection within 24 hours after birth.
