[Instruments of official communication by regulatory authorities on risks of drug use]

Active communication of authorities, such as the Federal Institute for Drugs and Medical Devices (BfArM) and the Paul Ehrlich Institute (PEI), including maintenance of contacts with health care professionals, as well as press and public relations work, are essential prerequisites for ensuring that information on the risks of using medicinal products reaches both affected patients and healthcare professionals quickly and in a targeted manner. The various instruments of targeted communication describe possible risks and also contain recommendations that help to reduce the risk of using a medicinal product. The supplementary public relations work aims to make the tasks and objectives of the authority known to the public and to experts with the goal of creating and expanding trust in the actions of the authorities. To this end, appropriate communication platforms must be established and accepted so that they are used by both experts and the general public and the authority is perceived and appreciated as a reliable source of risk information. The currently available instruments of targeted risk communication, such as Dear Health Care Professional Communication (DHPC), risk management plans, and educational materials are described in this paper as well as broader communication on official websites or towards the media. Finally, PEI's risk communication is highlighted with particular reference to COVID-19 vaccines.
