Nigerian families have refused 35 million dollars in compensation from US firm Pfizer over a drug trial blamed for children's deaths due to a DNA testing dispute, their lawyers said Tuesday. An out-of-court settlement over a 1996 meningitis drug trial that allegedly left 11 children dead and 189 others deformed was reached last year, but the families' lawyers have now called for a halt to the payouts. A letter written by the lawyers…asked a board of trustees appointed by the US pharmaceutical giant and Kano state government to immediately cease processing the compensation.
