Keep the clinic’s record.

Save the record supplied by the clinic or another official source. Keep your child’s name attached to it, especially when you have records for more than one child. A personal list can help you locate an event, while the original document preserves the information an organization may require.

The CDC recommends keeping vaccination records safe and up to date and asking your doctor or nurse how to get an official copy. Schools and childcare providers may have their own requirements, so check which document they accept.

If you save a scan or photo, give it a filename you can recognize later. Keep the paper original when you have one, and choose a consistent place for new documents.

Make a small index you can read quickly.

For your personal history, copy the vaccine name and the date it was given. Include the clinic or provider in a note so you know where to ask for the source record. Preserve names as written instead of guessing which abbreviation a clinic intended.

Use the administration date, even if the document arrives later. For example, a record received on June 8 might describe a vaccine given on June 2. The date you file the document should not replace the date of the event.

If a second document lists the same vaccine and date, compare it with the first before adding another event. Two copies may describe the same administration. Ask the issuing provider to reconcile conflicting details.

Ask for missing details rather than filling gaps.

If you can’t find a document, contact the clinic that gave the vaccine. Your state or local immunization information system may also have a record; the CDC’s records guide explains where to look.

Leave an unknown date or vaccine name unresolved while you request the source. A usual schedule or your child’s age cannot confirm what was actually given. Keep a note of the clinic you contacted and the document you’re waiting for.

When a corrected record arrives, update your personal history from that source. Retain enough context to recognize that the newer document replaces an earlier copy.

Keep a personal vaccine history in Diaper Days.

Use a Vaccines event to record the vaccine selections and the date they were given. Notes can retain the clinic, the source document’s location or a clarification you want to remember. You can look back at those saved events in History.

Keep the official immunization documents as well. Diaper Days is a personal care record; it does not issue vaccination certificates or decide whether your child’s vaccinations are complete.

Before the next appointment, find any dates or missing details you want to check and bring the clinic’s record. Ask the care team to review what comes next, then add confirmed events to your history afterward.
