Medical Readiness Reporting System is the tool built specifically to track immunization status and individual medical readiness across the military. It collects and maintains vaccination records and IMR data so all services—Army, Navy, Air Force, and Marine Corps—can verify readiness before deployment. The other systems serve different purposes: Dental Common Access System handles dental records, Armed Forces Health Longitudinal Technology Application is the DoD’s broad electronic health record, and the Military Health Service Population Health Portal focuses on population health data rather than individual immunization tracking. So MRRS is the appropriate system for immunizations and IMR.
