The Immunization Action Coalition (IAC) is an organization that distributes information about vaccines and the diseases they prevent.

[2] In partnership with the Centers for Disease Control and Prevention (CDC), their headquarters is located in Saint Paul, Minnesota, with member coalitions in the United States and Canada.

Having the goal of providing the public with information about immunization,[4] the IAC has three current functions: The coalition's Web site offers "Unprotected People Stories" about the consequences of vaccine avoidance,[5] and "Talking about Vaccines" which discusses general vaccine-related topics.

In 2012, the coalition launched a campaign to promote the fourth edition of The Vaccine Handbook: A Practical Guide for Clinicians.

[8] The World Health Organization lists the IAC on their Global Vaccine Safety page, noting the availability of their materials in various languages such as Korean, Vietnamese, and Turkish.
