There is no inoculation against TB in the US. If your husband's sister had TB and you live in the states, you had a PPD test to see if you had been infected. The test provided no protection to becoming infected in the future.
The TB vaccine, BCG, is one of the world's most widely administered vaccines, but the US doesn't use it because it provides virtually zero protection other than for certain types of TB (e.g., TB meningitis) in infants and young children. No effective TB vaccine exists, although there are groups (AERAS, based in MD) working on one.
The tine test also hasn't been used in years, being replaced by the PPD. The PPD is meant to serve more as a screening tool than a diagnostic one. It doesn't differentiate between latent infection and active disease.
