When Jim Humble "cured" the malaria patients, there did not seem to be any follow up with them. Did it really get rid of all of the microbes? Did it come back back to them later? Never the less, you have the advantage of being clean of malaria before you even go to Africa.
In your case, you do not have malaria. You haven't been bitten by the mosquito that causes it. The Miracle-Mineral-Supplement chemical lasts for 12 hours; then no longer exists in your body. I suspect that if you use Miracle-Mineral-Supplement every 12 hours at sufficient dosage (???), you will kill any malaria that enters your bloodstream during that time. Since you don't already have malaria, I'll bet that you could even maintain a daily maintenance dose of 6x2 and be relaxed about it. Then you would not need Antibiotics .
This is conjecture based only on what I've read so far.
