This site provides information about the use of contracts to acquire goods and services for the use and benefit of the Centers for Disease and Control and Prevention (CDC).

CDC uses contracts to purchase goods and services such as supplies, vaccines, Information Technology (IT), and equipment to advance the agency’s public health mission domestically and abroad to keep Americans safe and healthy where they work, live and play. In FY 2023, the Office of Acquisition Services (OAS) processed 10,881 contract actions. These contract actions totaled $7.9 billion supporting public health programs and research around the world.

Contracts definition

Contracts refer to a mutually binding legal relationship obligating the seller to furnish the supplies or services (including construction) and the buyer to pay for them. It includes all types of commitments that obligate the Government to an expenditure of appropriated funds and, except as otherwise authorized, are in writing.

In addition to bilateral instruments, contracts include (but are not limited to) awards and notices of awards; job orders or task letters issued under basic ordering agreements; letter contracts; orders, such as purchase orders, under which the contract becomes effective by written acceptance or performance; and bilateral contract modifications.When the federal government issues a contract, it is agreeing to provide funds in exchange for the delivery of goods or services from the contractor. Failure to perform and achieve the promised results or product outlined in the contract can result in legal action and financial consequences.

CDC awards both contracts and grants; the differences are defined below. Check out CDC’s Grants page for more information on CDC’s grant funding. [Read Less]
