Immunization Services Division (ISD)


The Immunization Services Division (ISD) aims to protect individuals and communities from vaccine preventable diseases throughout the lifespan.

Our Strategic Priorities:
  • Lead and implement national vaccination programs through the lifespan and oversee the Vaccines for Children (VFC) program
  • Ensure safe and effective protection from vaccine-preventable diseases; set nation’s immunization schedule and monitor its impact based on latest available evidence
  • Support state and local health departments with funding and technical assistance to immunization programs
  • Monitor use and estimate vaccination coverage to determine where additional efforts are needed
