Monitoring Childhood Immunization at the State Level | International Vaccine Access Center

The International Vaccine Access Center (IVAC) at the Johns Hopkins Bloomberg School of Public Health has developed a series of State-Level Immunization Monitoring Briefs and webpages displaying tailored information on the extent to which children are protected against vaccine-preventable diseases across the United States. The aim of this activity is to build and sustain policy commitment for the value of childhood vaccination at the state level.

These resources focus on non-seasonal vaccines recommended to all U.S. children, with briefs developed for all 50 states and the District of Columbia. We hope that the data contained in these pages will be shared with policymakers to inform immunization decision-making.

Note: The measles case numbers contained in these briefs will be updated on an ongoing basis. Please contact ivac@jh.edu with any questions.

Our Github repository contains code and data to generate these briefs.
