Pandemic Production Act This bill authorizes the Department of Health and Human Services (HHS) to take actions to develop and maintain the capabilities of domestic industries to produce materials necessary for the pandemic response strategy of the United States. It also establishes the Pandemic Production Act Fund to support these efforts. Among other activities, HHS may purchase, or commit to purchase, essential medical technologies and related materials and install equipment in, or otherwise modify, government-owned or privately owned industrial facilities to support domestic production capacity. Before using these authorities, HHS generally must make specific determinations and findings related to the necessity of the action but may waive these requirements during a declared national emergency.
