If the immune status of an elderly patient, or any patient, is in question, the BCG vaccination should be held until the immune status of the patient has been evaluated. BCG Vaccine for percutaneous use, is an attenuated, live culture preparation of the Bacillus of Calmette and Guerin (BCG) strain of Mycobacterium bovis.1 The TICE® strain used in this BCG Vaccine preparation was developed at the University of Illinois from a strain originated at the Pasteur Institute.The medium in which the TICE® BCG organism is grown for preparation of the freeze-dried cake is composed of the following ingredients…

The intensity and duration of the local reaction depends on the depth of penetration of the multiple puncture device and individual variations in patients' tissue reactions. Following a single vaccination, 99.3% of all infants studied became PPD positive, with 84.2% still being positive after 8 years. The papules reach a maximum diameter (about 3 mm) after 4 to 6 weeks, after which they may scale and slowly subside.

Two countries that have never used it routinely are the United States and the Netherlands (in both countries, it is felt that having a reliable Mantoux test and therefore being able to accurately detect active disease is more beneficial to society than vaccinating against a condition that is now relatively rare there).[94][95]. Centers for Disease Control and Prevention. A review of each patient's immunization records to include history on reactions to immunizations should be completed prior to vaccination. Because the living bacilli evolve to make the best use of available nutrients, they become less well-adapted to human blood and can no longer induce disease when introduced into a human host.
