willcousa,

In any large scale innoculation program some people get the disease from the innoculation, so it is a two-edged sword.

This is not true in general. Some older vaccines have used a weakened live organism, in which case this could happen. Most if not all modern vaccines use protein fragments from the surface of the organism to trigger the immune system. Because the whole pathological organism (virus, bacteria or parasite) is not present it is impossible to contract the disease from such vaccinations. There could, however, be allergic responses in rare cases.
