Those injured will need their clinical negligence solicitors to investigate the results of the animal trials, the supervision of the trial and whether or not the drug was in fact defective.
Clinical negligence claims solicitor, Paul McNeil said: "The patients may well have signed a document enabling a no-fault compensation scheme to be invoked, in case of a medical accident. Moreover, if negligence or product defect is accepted by the manufacturer at an early stage this may provide some compensation. If not, the families could face a lengthy legal battle."
