FDA's mission is to protect and advance public health by helping to speed innovations that provide our nation with safe and effective medical products and that keep our food safe. The Agency achieves this by applying the latest technology and science-based standards to the regulatory challenges presented by drugs, biologics (vaccines, blood products, cell and gene therapy products, and tissues), medical devices, food additives, and, since 2009, tobacco.
