Having actually grown bacteria in lab conditions, I can say that it's not that out of control.
This does not however mean that all those micro-organisms are lethal or even irritating.
Most of those encountered on a daily basis are members of the Coccus or Bacillus family and relatively harmless or beneficial.
If you enter a toilet you are instantly exposed to a million billion poop-bacteria and it doesn't kill you. E.coli is a bacterium that is found in the human colon among other places and only a few rarer genomes of it are pathogenic (disease causing).
Terminating all bacteria, or reducing their quantity significantly, from our enviroment would jeopardize our immune system and resistance to forms of bacteria. Excess cleanliness is something to avoid.
If you have a child, fart in her face and expose her to a nuclear blast of bacteria.
No vaccine could ever hope to beat a natural immunity.
