TB is a mycobacteria: For viruses, not living cells (just snippets of dna/rna surrounded by protein coating designed to attract certain cell receptors & ingestion as a trojan horse), vaccines (to induce the immune system to produce antibodies which recognize & neutralize the few outer proteins) have been the dominant successful approach to reducing infection. Mycobacteria: complex living cells targeted with antibiotics.
