Malaria halt

Good news for those down with malaria. Manuel Patarroyo, a biochemist from Colombia, claims that he is about to develop a vaccine against the disease, one of the oldest scourges of mankind. The vaccine is being tested in tropical countries like Tanzania and Thailand. Reports from Tanzania indicate that Patarroyo's chemically-engineered vaccine provides adequate protection. More information on its preventive capacity is expected by end-November, when test results on 600 people vaccinated in Zambia will be declared.
