Who Should Not Receive the BCG Vaccine?
There are certain individuals who should not receive the BCG vaccine, including:
- Immunosuppressed people
- Pregnant women.
Immunosuppressed People
The BCG vaccine should not be given to people who are immunosuppressed (e.g., people who are
HIV-infected) or who are likely to become immunocompromised (e.g., people who are candidates for organ transplant).
Pregnant Women
The BCG vaccine should not be given during pregnancy. Even though no harmful effects of the BCG vaccine on the fetus have been observed, further studies are needed to prove its safety.
Testing for TB in BCG-Vaccinated People
The BCG vaccine may interfere with the TB skin test, showing a positive skin test reaction in people who have received the vaccine. This complicates decisions about
tuberculosis treatment because it is not possible to tell whether a person has
latent tuberculosis or a prior BCG vaccination. For these reasons, most
tuberculosis treatment recommendations do not consider whether a person received the BCG vaccine.
