The MedShield Act of 2025 aims to enhance the United States' preparedness for pandemics by establishing a program that utilizes artificial intelligence and other technologies. The main objective is to create a comprehensive system that can effectively respond to biological threats, thereby reducing the need for emergency measures like those seen during the COVID-19 pandemic. Key provisions of the act include the establishment of the MedShield program, which will be overseen by the Secretary of Health and Human Services.
