There's some work in looking at alternative ways of administering the BCG vaccine (iv injection, inhalation). The IV numbers are pretty promising -- if the monkey numbers hold. I hope that someone, somewhere pushes it into human trials soon.
There's also the nebulous but very nice-sounding "non-specific effect" with it. Who knows.
