The Merck Childhood Asthma Network, Inc. (MCAN), a nonprofit 501(c)(3) organization funded by the Merck Foundation, was established in 2005 in Washington, DC as the only private foundation focused solely on addressing the complex issue of childhood asthma in the U.S. MCAN’s mission was to enhance the quality of life for asthmatic children and their families and reduce the burden of the disease on them and society.

MCAN funded the implementation of projects in varied settings to improve high quality asthma care for children. During its tenure, MCAN granted more than $20 million to programs set in some of the nation’s most impoverished, at-risk communities to study the impact of evidence-based interventions on symptoms and emergent/urgent care use of children living with asthma.

MCAN thanks its many partners and supporters from the public and private sectors. Without input from and the generous support of these organizations, MCAN would not have been nearly as successful in improving the care and quality of life of children with asthma.
