Nigeria has filed a lawsuit demanding $7 billion in compensation from the Pfizer drug company over allegations that testing of a meningitis drug ten years ago led to the deaths of some children.
Monday's lawsuit is in addition to a separate $2 billion action filed recently by the government of the northern Nigerian state of Kano.
Both suits accuse Pfizer of failing to get permission to conduct tests of its meningitis drug on 200 children suffering from the disease.
Half the children got the new medication, the others got a drug that was already on the market.
Nigerian officials blame the deaths and disability of some of the children on the company. The company denied doing anything wrong in response to the earlier suit, which is similar to this latest legal action.
