Via FP's The Top Ten Stories You Missed in 2006:
In 2006, bird flu didn’t become the killer pandemic everyone feared. In fact, there were no confirmed deaths in developed countries from bird flu. But the alarm, stoked by Western media reports, led to an unexpected—and unfortunate—outcome: A rash of abnormal behavior, hallucinations, and even deaths attributed to Tamiflu, the medicine marketed as a key drug capable of fighting the disease. In November, the Canadian health ministry issued a warning on Tamiflu after 10 Canadians taking the drug had died suspiciously. And the U.S. Food and Drug Administration received more than 100 reports of injury and delirium among Tamiflu takers for a 10-month period in 2005 and 2006. That’s nearly as many cases as were logged over the drug’s five-year trial period. For now, the cure seems worse than the disease.
