A PROGRAM OF ACTION AND COOPERATION: Since 2001, a series of measures have been taken by the Member States, the European Union and the International authorities to reinforce the preparation and response to biological and chemical terrorist acts. It is essential that the Member States can mutually consult and coordinate their preparation and response as widely as possible. THE ROLE OF THE HEALTH SECURITY COMMITTEE: Together with the health security committee, the European Union has setup a mechanism of consultation and coordination that can be recommend and guide joint action in an emergency, and guarantee the coherence of the counter-actions throughout the Union. This is a committee also constitutes the framework within which the emergency strategies and model-simulations are exchange, and in which assistance in the form of expertise and other resources can be obtained among the Member States. IN THE YEARS TO COME: The future European Centre for the prevention and control of disease, the implantation and functioning of which will start in Sweden in 2005, will play a fundamental part in the harmonisation of the European response to any eventual terrorist acts, whether biological or chemical.
