The National Conference on Immunization and Health Coalitions (NCIHC) is a gathering of coalition leaders, staff and board members; public health workers and experts; and community advocates. The conference occurs every two years and is the product of a national volunteer planning committee. The Planning Committee works closely with a local organization to host the meeting. Historically, attendance at the meeting ranges between 200 and 400 participants and there are 2 ½ days of expert presentations and peer learning opportunities. Not only is the Host Organization supported by the Planning Committee, there is an experienced Program Committee and an experienced Fiscal Organization to manage nationally-based major grants.
