Dr. Stephen Hoffman has been searching for a way to eradicate malaria for the past 30 years. He may have found a vaccine to do it:
There was no way Hoffman was going to ask US Marines to line up for a thousand mosquito bites each. But he decided to repeat the irradiated-mosquito experiments to understand the science better.
Once again, Hoffman signed himself up for the study. In the mid 1990s, he returned to the Walter Reed Army Institute of Research to stick another pint-size container of insects against his arm. This time, the cylinder swarmed with hundreds of malaria-infected mosquitoes, each having been buzzed with a dose of radiation. The bloodthirsty insects left a circle of swollen red skin on his arm, but Hoffman didn’t stop until he had been bitten by 3,000 mosquitoes.
Weeks later, when he was infected with malaria, he didn’t get sick.
