Refugees being resettled in the United States, unlike immigrants seeking residency, have not been subject to immunization requirements (1). Without immunization, refugee communities overseas and in the United States are vulnerable to outbreaks of vaccine-preventable diseases that can disrupt the resettlement process and require costly public health responses (2,3). CDC's Division of Global Migration and Quarantine has regulatory authority to prevent communicable disease importation among the approximately 70,000 refugees resettled in the United States each year.
