Immunization Services Division (ISD)


The Immunization Services Division (ISD) works to protect people across their lifespan from vaccine-preventable diseases by equitably increasing access, confidence, and demand for vaccines.

Our Strategic Priorities:

Increase Vaccine Access

  • Use data to identify areas and populations of concern.
  • Improve vaccine access for low-coverage areas across urban, suburban, and rural communities.
  • Increase investments to promote cost-free access to adult vaccination.
  • Improve on successes of the Vaccines for Children (VFC).

Promote Vaccine Confidence and Demand

  • Work with partners to build vaccine confidence and demand in populations with low coverage.
  • Provide technical assistance and support to partners on building vaccine confidence.
  • Analyze data and conduct research to understand the characteristics and drivers of vaccine confidence.
  • Explore and implement creative strategies to mitigate mis/disinformation.

Enhance Data, Research, and Evaluation

  • Deepen the breadth and accuracy of immunization data on vaccine coverage, access, and demand.
  • Expand and modernize immunization data systems, surveys, and infrastructure.
  • Collaborate across the CDC and with partners to improve the quality and interoperability of immunization data and data systems.
  • Conduct research, evaluate intervention efficacy, and disseminate findings to improve vaccine access, confidence, demand, and coverage.

Strengthen Program Support for Partners

  • Strengthen technical assistance and resources to build partner capacity, including on data, vaccine confidence and demand, reducing disparities, and improving access for all.
  • Promote increased collaboration and information sharing across partners.
  • Identify, sustain, and scale evidence-based interventions across partners.
  • Work with a wide range of partners to develop innovative programs to improve vaccine coverage.

Improve Vaccination Equity

  • Lead, coordinate, and amplify governmental and partner efforts to reduce vaccination disparities.
  • Expand research to uncover drivers of vaccine coverage by population and geography.
  • Prioritize equity in the planning, allocation, and implementation of ISD resources.
  • Use data to identify and implement opportunities to increase uptake in populations experiencing vaccination disparities.

Enhance Vaccination Response Readiness

  • Use data to identify at-risk communities and predict emerging threats.
  • Collaborate to develop, maintain, and improve emergency response data and interoperability of information systems.
  • Coordinate, build capacity, and enhance readiness capabilities at the federal, state, and local levels.
  • Build strength and resilience across the immunization workforce.
What We Do:
  • Vaccines: We oversee public sector vaccine purchase and distribution.
  • Vaccine Programs: We administer the VFC and Section 317 Immunization Program for 64 awardees by guiding program accountability, evaluation, and providing technical assistance.
  • Surveillance: Our scientists lead vaccination coverage assessment across the lifespan, evaluating methods to improve immunization service delivery, and assessing the impact of interventions.
  • Information Systems: Facilitate the use of immunization information systems to ensure that immunization programs and providers have the data they need for decision making.
  • Education: We provide education, materials, and training for the public, healthcare providers, and partners.
