Ineffective in example sentence
We are all different, and a disease that I might have, if I had Alzheimer's disease or Parkinson's disease, it probably would affect me differently than if one of you had that disease, and if we both had Parkinson's disease, and we took the same medication, but we had different genetic makeup, we probably would have a different result, and it could well be that a drug that worked wonderfully for me was actually ineffective for you, and similarly, it could be that a drug that is harmful for you is safe for me, and, you know, this seems totally obvious, but unfortunately it is not the way that the pharmaceutical industry has been developing drugs because, until now, it hasn't had the tools.
