This report offers insights into the risks and vulnerabilities of the supply chains of medicines and medical devices. Policy options to anticipate and mitigate risks of shortages of medicines and medical devices, both routinely and in the context of severe crises, are analysed. Most importantly, the report shows that strengthening the long-term resilience of medical supply chains requires collaborative approaches that balance measures best undertaken by the private sector with those more appropriately managed by governments or supranationally.
