Immunize.org is an award-winning 501(c)(3) nonprofit organization, headquartered in Saint Paul, Minnesota. We work to ensure that healthcare professionals and the public are up to date on all aspects of vaccination and advocate for policies that remove barriers to vaccination.

Our Mission

Immunize.org works to increase immunization rates and prevent disease through its practical educational materials designed to enhance the quality and safety of immunization services. We work with partners to advocate for policies that increase vaccination of people of all ages. We also facilitate communication about the safety, effectiveness, and use of vaccines within the broad immunization community of patients, parents, healthcare organizations, and government health agencies.

Physicians, nurses, pharmacists, and other healthcare professionals at every level of the immunization community, including both the public and private sectors, rely on Immunize.org in their daily work to increase immunization rates across the lifespan.

Our History

Immunize.org is one of the earliest websites devoted to immunization.

In the 1980s, as a family practice resident in Wisconsin, our founder and executive director emerita, Deborah L. Wexler, MD, developed a great interest in hepati­tis B.

In 1986, Dr. Wexler moved to the Twin Cities where she first joined the staff of the Indian Health Board Clinic in Minneapolis, and in 1988, the West Side Community Health Center (now Minnesota Community Care) in St. Paul.

In 1990, Dr. Wexler, along with others, founded the Hepatitis B Coalition, which evolved to become the Immunization Action Coalition in 1994, and Immunize.org in 2022.

Learn more about Dr. Wexler’s unparalleled career in vaccine advocacy and her impact on Immunize.org today. 

For nearly three decades, CDC has been an important partner, working with and providing financial support to Immunize.org to educate healthcare professionals about U.S. vaccine recommendations. CDC recognized Immunize.org’s accomplishments in 1997 with the prestigious Partners in Public Health Award for efforts “instrumental in achieving high levels of routine infant hepatitis B immunization.” Learn more about recognition for our work.

Today, Immunize.org is a premier non-profit web-based resource for practical, user-friendly immunization information, averaging more than 25,000 online visits per day.

Audience: Healthcare Professionals

Immunize.org website users download more than 8 million ready-to-copy PDF documents from the website annually. These include a repository of all federal Vaccine Information Statements (VISs) in more than 45 languages to make vaccine information more accessible to patients whose preferred language is not English.

Also included is a collection of hundreds of immunization education materials for healthcare professionals and patients, some in several languages.

These materials are available free of charge, and you are encouraged to download them, make copies, and distribute them. Our team makes almost daily additions and updates to the content of Immunize.org.
