Nigerian families got the go-ahead this week from the U.S. Supreme Court to sue the drug company Pfizer for carrying out an illegal trial of a new antibiotic on their children that produced fatalities.
 
The families say Pfizer did not get the proper consent to test the drug Trovan on 200 sick children during a meningitis outbreak in 1996. Later testing linked the drug to liver failure. It is banned in the European Union.
