Johnpeter Mwolo was 15 when he was diagnosed with Type 1 diabetes.
His body, unable to produce the hormone critical for regulating blood sugar, would now rely on manufactured insulin. He learned to give himself the treatment — four injections a day.
But as he was growing up in Tanzania, insulin was expensive and not always available. Mwolo resorted to rationing his insulin, sharing a vial with his cousin, who also had Type 1 diabetes. "It was one vial to two people," he says. "Many of the necessities that we are supposed to have are not there."
