Personal experiences with the diseases of HIV, TB, and malaria motivate the scientists.
I asked one scientist: "So, did you always want to be a scientist? Even when you were a child?"
His reply was "Yes, yes. Actually, my interest in drugs started when I was about 15 or 16. I got struck by malaria the first time ever. And I was so sick I thought I was going to die. I had never been so sick in my life. So I thought, after I recovered, I thought I'm going to make a difference to helping people."
