Information concerning difficulties encountered in establishing a durable flow of vital medical supplies to Iran in the context of U.S. sanctions against the country; and particularly the reluctance of key parties to be involved in the supply despite the exemptions that are supposed to allow humanitarian goods to be shipped to Iran. This reluctance, due to substantial overcompliance with the sanctions, has impeded the establishment of lasting arrangements for procuring and shipping medical supplies to Iran, forcing a shift toward ad hoc arrangements that add complexity, time, costs and uncertainty to the supply process, which negatively impact the right to health and right to life of patients for whom the supplies are destined.
