I imagine it takes a more aggresive formulation to be effective orally, whereas injection is a straight shot into the fray of the immune system's war on pathongens. These more active forms seem to raise the risk of mutation to active virulence.

The normal way of transmission is eating something that is contaminated with poop of an infected person. So it is probably easier to create a vaccine that can be "eaten".
