Answer:
we should be worried of resistance because when a resistance to an antibiotic is high, it is harder to treat the patient. If we build an immunity/tolerance to the flu shot, that would be a worldwide epidemic disaster. Same with malaria. One thing that is at fault for this i'd say is the overuse of perscription medicine/bacterial shots. Humans go into the doctors npow a days for anything. So the human race being so overdramatic really puts the whole tolerance problem on the line.
