As a result of this, the Council agreed to a Commission proposal to impose a moratorium until 31 December 2003 on the conduct of such research under the programme pending the development of detailed guidelines and safeguards. However, certain activities are explicitly excluded from the overall framework programme in their entirety. These are research activities aiming at human cloning for reproductive purposes, research activity intended to modify the genetic heritage of human beings and research activities intended to create human embryos solely for the purpose of research or for the purpose of stem cell procurement.
