Nigeria is suing pharma giant Pfizer for $7 billion, claiming the company carried out improper trials on children. 200 children in the state of Kano died, and others developed deformities, after Pfizer tested Trovan, an experimental antibiotic, during a 1996 meningitis outbreak. Nigeria claims the tests were unauthorized, but Pfizer insists the company had consent.
A number of individual families in Kano sued Pfizer after the deaths, but this is the first time Nigeria has filed; Kano is seeking a separate $2.7 billion. BBC analysts surmise that the incident increased Nigerian distrust of Western medicine, complicating the effort to vaccinate the population against polio, which has resurfaced there.
