Primary Immunodeficiencies

Primary Immunodeficiencies

The Childhood Primary Immunodeficiency Program at the Maria Fareri Children’s Hospital at Westchester Medical Center and New York Medical College is a multidisciplinary and comprehensive program dedicated to the diagnosis, prevention, treatment and long-term follow up of children diagnosed with primary immunodeficiency syndromes. The program consists of several “state of the art” programs in Newborn Screening, Prevention, Genetic Diagnosis, Stem Cell Transplantation, Reduced Intensity Conditioning and Adoptive Cellular Immunotherapy. The program also provides a unique opportunity for clinical, translational and basic research for students, residents, and fellows focused on the biology and treatment of primary immunodeficiency in children. Most importantly, the program is designed to provide customized and personal care and long-term follow-up to each child with a primary immunodeficiency. The program is one of 43 centers in North America participating in the National Institutes of Health-funded Primary Immunodeficiency Treatment Consortium. Learn more.
