Why does the immunization section specify that TB skin testing (PPD) must be done regardless of whether BCG was administered in childhood?
Although BCG does protect against some forms of childhood tuberculosis often this protection does not carry over into adulthood. Previous BCG vaccination may cause a positive result with PPD testing but the response is usually <10 mm of induration. A response that is 20mm or greater generally means that the person has latent TB infection (LTBI) and should be treated accordingly. Therefore testing is currently recommended regardless of prior BCG vaccination. "A history of BCG vaccination, with or without a BCG scar, should not influence the decision regarding whether to treat LTBI. The criteria previously described should be applied without modification (164)." -- from the CDC website What to do if you don't know your Rice ID# yet.
