Immunization Record Redaction with anonym.plus

Clear IDs from the file while the shot schedule stays.

Immunization-record redaction is the removal of patient IDs from a vaccine file. It meets the HIPAA Privacy Rule (45 CFR Part 164) for reuse. anonym.plus runs locally and keeps the vaccine, lot, dose, and dates that public-health work needs.

When this applies

Registries and coverage studies need true shot and schedule data, but the file carries the name, DOB, and ID. Redaction clears those and keeps the useful fields.

How anonym.plus handles it

  1. Load the file into anonym.plus on your device.
  2. It finds the name, DOB, and IDs.
  3. The vaccine, lot, dose, and date fields stay (dates can go broad).
  4. Black out or swap the confirmed PHI.
  5. Save the clean file on your device.

Limitations & cautions

For child files, guardian details are PHI too and must go. Shot dates may be needed exactly for schedule work. Broaden them only when your study allows, or you break the gap math.

Frequently asked questions

Are guardian details on a child's file removed?

Yes. A parent or guardian ID in a child's file is PHI and is flagged for removal with the patient's own.

Can I keep the lot numbers?

Yes. Vaccine type, lot, and dose stay. They are needed and are not patient IDs.

Does it support registry exports?

Yes. Printed cards and structured registry exports both work locally.
