About Us: Immunization Healthcare Branch (IHB)
Defense Health Agency Immunization University Logo

In October 2014, the Military Vaccine Agency-Vaccine Healthcare Centers Network (MILVAX-VHCN) transitioned into the Defense Health Agency (DHA) as the Immunization Healthcare Branch (IHB), a vital part of the DHA's Public Health Division. The DHA IHB will continue all the functions carried out by MILVAX-VHCN for uniformed personnel, and will expand the support and services we provide on behalf of military dependents and retirees worldwide. The DHA IHB continues to support all DoD immunization programs, and to provide clinical consultative services, educational support, and training resources for the entire DoD family.


We are committed to provide and enable the best quality and most responsive patient-centered immunization healthcare and readiness.


To enhance the Military Health System focus on health and healing by supporting immunization program efficacy, safety and acceptability, and enabling solutions that address personalized medicine and improved evidence based practices.

Immunization University

A major component of the IHB education and training vision is “Immunization University”, an informal collection of guidelines and training resources to help staff make every immunization an excellent one. Designed to enhance the skills of healthcare workers from a variety of backgrounds, Immunization University (ImzU) offers training on vaccine products and immunization services through on-line distance learning and on-site classes sponsored by IHB. CE Credits are available for on-site training events. Certificates of completion and consolidated student transcripts are available via the ImzU LMS, and may be accessed online.
