The TB part is interesting, because the vaccine that's "available" in the US (in quotes because the supply chain probably is not fully functional) hardly works at all. It's a major problem for prisoners, health care workers who currently have to use CBRN respirators, and pretty much everyone who lives in certain highly contaminated cities, mostly on the west coast.
