What if I have been vaccinated with BCG?

BCG is a vaccine for TB. This vaccine is not widely used in the United States, but it is often given to infants and small children in other countries where TB is common. BCG vaccine does not always protect people from getting TB.

If you were vaccinated with BCG, you may have a positive reaction to a TB skin test. This reaction may be due to the BCG vaccine itself or due to infection with the TB bacteria. Your positive reaction probably means you have been infected with TB bacteria if
You recently spent time with a person who has active TB disease; or
You are from an area of the world where active TB disease is very common (such as most countries in Latin America and the Caribbean, Africa, Asia, Eastern Europe, and Russia); or
You spend time where TB disease is common (homeless shelters, migrant farm camps, drug-treatment centers, health care clinics, jails, prisons).

BCG is not TB vaccine - the theory is BCG stimulates immune response to infections and perhaps some cancers

wish it was more effective in both.

BCG is not a specific vaccine for TB it is an attempt to give something even if it is not all that effective

by the way TB is caused by direct contact and being PPD pos does not mean you had TB just that you were exposed-
normal healthy adults can come in contact with TB patients and have a good chance of not contracting the active disease - as anyone familiar with TB knows - it preys on the sick and underfed and is most common in crowded lower income areas.
