Report to ImmuNet All Vaccines Administered
ImmuNet is Maryland's Immunization Information System (IIS). It is a secure web-based registry operated by the Center for Immunization at the Maryland Department of Health (MDH). ImmuNet information is confidential and available only to authorized users. To read more on the benefits of IIS please go here.
As of October 2019, all vaccinations administered in the State of Maryland are required to be reported to Maryland's Immunization Information System, ImmuNet, regardless of patient opt-out status in ImmuNet (see more info about patient opt-out here).
Note: per §18–109(d)(6)(II), this does not apply to vaccine providers who administers a vaccine in a nursing facility, an assisted living program, a continuing care retirement community, or a medical day care program.
Reporting COVID-19 Vaccinations
All administered doses of COVID-19 vaccines must be reported to ImmuNet per the CDC Provider Agreement and within 24 hours per the Governor's Executive Order 21-01-05-01. To meet this requirement, the most efficient options to report to ImmuNet are through Electronic Health Records (EHRs) or csv file uploads.
Please see here for the list of CDC/MDH-required data elements to report to ImmuNet.
Providers eligible to order COVID-19 vaccines through ImmuNet must report administered doses under each location’s unique Organization ID for accurate vaccine allocation and inventory reconciliation.
To ensure you are in compliance with the State Statute §18–109(d)(6)(I)3 to Report to ImmuNet all vaccines administered, please see the section below that applies to you.
How can providers tell if they are already reporting to ImmuNet?

Providers Who Are Already Reporting to ImmuNet
Providers Who Are Not Reporting to ImmuNet
Providers who participate in the CMS Promoting Interoperability (PI) programs (aka EHR Incentive Program, Meaningful Use or MIPS) may already be registered to report to ImmuNet. If you are still in the queue and have a TEST file ready to submit, please contact the Public Health Reporting Help Desk. Note that participants must report from certified technology with Query/Response (bidirectional data exchange) capabilities and send NDC codes.
Providers not participating in the CMS Promoting Interoperability (PI) programs should also register to get in the queue for testing. Please visit the Public Health reporting webpage to view the onboarding steps (Registration, Testing, and Production), including the ImmuNet specifications and data transport options. Once registered, you will receive an acknowledgment that you have been placed in the onboarding queue, and an onboarding/validation staff will contact you to get started.
Multiple locations sharing the same electronic Health Records (EHR) system can register and onboard together as a group effort. However, each location/site will be assigned a separate Organization ID in ImmuNet.
ImmuNet supports bidirectional data exchange through the Maryland State Health Information Exchange partner, CRISP. Instructions for onboarding with CRISP can be found here.
Note: ImmuNet conforms to the CDC HL7 2.5.1 Implementation Guide for Immunization Messaging, Release 1.5 and Addendum, including supporting Query/Response, acknowledgment messaging, and the receipt of National Drug Codes (NDC) for newly-administered immunizations.
The Maryland Department of Health (MDH) strongly recommends reporting vaccination data to ImmuNet through an EHR/EMR. A direct connection between your EHR/EMR and ImmuNet is the most efficient, cost-saving and reliable method to ensure your vaccination data is reported in compliance with Maryland law. If you do not have an EHR or EMR, MDH strongly recommends getting an EHR/EMR (there are a few low-cost or free options available).
If EHR/EMR is not a feasible option for you, there are two other methods of reporting to ImmuNet:
1. Manual Data Entry
Enter patient vaccination data (other than COVID-19) manually in ImmuNet on a daily basis. Note this option does not apply for COVID-19 vaccination data reporting. For vaccination data other than COVID-19, please review the ImmuNet training videos for guidance. You will need to have an ImmuNet account.
2. CSV files
Upload CSV files on a daily basis. There are two CSV options:
a. Via CRISP (preferred option for long-term reporting)
Using the CRISP CSV template, submit the single file for CRISP to convert to HL7 format and automate the submission to ImmuNet. Since the file will be converted to HL7 format, the values must conform to the standardized formats in the table of the ImmuNet HL7 specifications (Appendix B).
b. Directly in ImmuNet
Per the ImmuNet CSV specifications, see page 7 for the link to download and submit two file templates (immunization and patient files. 100mb is each file's limit.
Please contact the ImmuNet Help Desk when you are ready to submit a test file. Do not include real patient data in your test file and do not email any files for confidentiality/security reasons.
Once testing is completed, there are two ways to submit CSV files on an ongoing basis:
i. Upload using SFTP
You will need an SFTP client. See page 3 of these instructions here.
ii. Upload directly in ImmuNet (only for option b above)
See instructions here. You will need to have an ImmuNet account.
If you do not have an ImmuNet account, please complete the ImmuNet Enrollment form here. Hard copies (here) can be downloaded for printing and distribution.
