A note from Dr. Joe Schwarcz:
After our November 26 debate Andre Saine and I agreed to ask each other questions that would be answered in writing and posted on our websites. Mine were ready a few days after the event; I have just received Andre’s. Because I had agreed to post his answers, I am doing so here with some trepidation. The reason is that there is some dangerous advice here about antibiotics and malaria prophylaxis, but I think our readers will see through this.
