Vaccination records: what to keep, children and adults

Vaccination records occupy a different position from everything else in a medical file, and it is worth being clear about why before discussing how to keep them.

Every other document in the file exists primarily for a clinician. A lab report, a discharge summary, a prescription — these are read by the person treating you, and their audience is clinical.

Vaccination records are read by administrators. A school asks for them at admission. An employer asks in certain sectors. A visa office asks for particular certificates for particular destinations. A college hostel asks. These are not clinical assessments; they are document checks, and a document check fails on the absence of the paper rather than on anything about the person.

That has two consequences. The record has to be producible on demand, at short notice, often years or decades after the events it records, and often by someone who was not present for them. And it has to be producible in a form the asking party accepts, which is frequently the original or a certified copy rather than a photograph.

One clear boundary: this is about keeping the record. It is not about which vaccines, for whom, or when — that is the national immunisation schedule and a clinician's territory, and nothing here should be read as covering it.

For a child, the immunisation card issued and filled in at the time is the primary record, and it is closer to irreplaceable than most people assume.

The reason is how the underlying records are held. Entries are made contemporaneously by the person administering the dose, across what may be several providers over several years — a government facility for some, a private paediatrician for others, a camp for one. There is no single custodian holding a consolidated copy, and each provider's own retention is its own affair and finite. A card lost at age nine cannot generally be reconstructed by writing to anyone, because there is nobody holding the whole of it.

So the card is treated as an original document rather than as a working paper. It stays in the person's file, in a protective sleeve, and copies are what travel to admissions and appointments.

Two practical points. Entries are frequently handwritten and fade or smudge, which is a further argument for copying early rather than at the point of need. And a card with gaps — doses given elsewhere and never entered — is common; the useful response is to file whatever separate documentation exists for those doses alongside the card rather than annotating the card retrospectively, since a note added later by a family member is not the same class of record as a contemporaneous entry.

This matters practically because the card follows a person into adulthood, long after the parent who kept it stops managing their records.

A copy of a vaccination record needs to satisfy an administrative check, which is a higher bar than being legible to a family.

Capture the whole card, both sides, flat and square, with every entry legible at full size and the facility's stamps and signatures included. Stamps and signatures are the part an administrator looks for, and they are the part most often cropped out or lost to glare, because they sit at the edges and are frequently in ink that reflects.

A photocopy on ordinary paper, taken while the card is in good condition, is worth having alongside the digital copy. It is the artefact that can be handed over when an original cannot be, and unlike thermal or handwritten originals it does not deteriorate.

Name the digital file so it can be found by someone who did not create it — person, then date, then a plain description — and store it with the household's other records rather than in a camera roll.

One thing a copy generally cannot do is substitute for an original where the asking party specifies an original or an attested copy. That is a documentary requirement set by whoever is asking, not a judgement about authenticity, and it is the reason the original is kept safe rather than carried. Where a certified or attested copy is likely to be needed — an admission, a visa application — the requirement is worth confirming with the asking party before the appointment rather than after.

Childhood immunisation has a custodian: a parent, and a card designed for the purpose. Adult vaccination generally has neither, and this is the single largest hole in most people's records.

An adult receiving a vaccine typically gets a receipt, a slip, or nothing at all, from a provider who holds their own record for their own retention period. There is no adult equivalent of the childhood card issued by default, so unless somebody creates one, the record exists only as scattered paper.

Some categories are better served. Vaccination against COVID-19 in India generated digital certificates through the government platform, retrievable rather than dependent on a slip. Certain travel-related vaccinations are recorded on the International Certificate of Vaccination or Prophylaxis, a standardised booklet whose entire purpose is to be presented at borders, and which functions as a travel document and should be kept with the passport rather than in the medical file. Occupational vaccination in healthcare and some other sectors is often recorded by the employer, which means the record sits with an organisation the person may leave — a copy obtained while still employed is considerably easier to get than one requested afterwards.

Everything else falls to the individual. The practical implication is that an adult's vaccination record is a document somebody has to decide to maintain, and the moment to add to it is when a dose is given, not when proof is demanded.

The instrument that closes the adult gap is unglamorous: a single running list, one per person, maintained for life.

Each row records what the documentation says, transcribed rather than recalled: the date, the name of the vaccine exactly as printed on the slip or certificate, the batch or lot number if it appears, the facility, and who administered it. Where a document exists, the row also records where that document is filed, on paper and digitally.

Three disciplines make it reliable.

Entries are made from a document, at the time. A row added from memory months later is a recollection sitting in a record, indistinguishable in appearance from a transcribed entry and materially different in reliability — and if a memory-based entry is unavoidable, it should be marked as such.

Names are copied as printed, without being converted to a more familiar term, abbreviated or corrected. Naming across manufacturers and formulations is inconsistent, and standardising it is an interpretive act performed by someone not positioned to perform it.

And the log records what happened rather than what it means. It does not note whether a course is complete, whether something is due, or whether a record is adequate for a purpose. Those are assessments for a clinician or for the party asking, and a log that stays factual keeps its value precisely by not attempting them.

A plain spreadsheet or a page in the front of the file is sufficient.

It is worth knowing the shape of the common requests, because each wants something slightly different and the differences are documentary rather than medical.

School and college admission typically asks for the immunisation card or a copy at enrolment, sometimes on the institution's own form to be filled in and stamped by a clinician. That last variant needs the card in hand, since somebody has to transcribe from it.

Employment in certain sectors asks for evidence of specified vaccinations, and what is required is set by the employer or by the regulation applying to that work.

Visa and immigration requirements are the most exacting, because they are set by another country and are specific about the form. Certain destinations require particular certificates in a particular format, and the standardised international certificate exists for exactly this reason. Requirements change and are set by the destination, so the destination's own official source is the only reliable one.

Institutional stays — hostels, some care settings — have their own document lists.

What these share is that a request is a document request with a deadline. It is answered by producing paper, not by explaining what was received. That is the whole case for keeping the record in a producible form: the record's job is to satisfy a check, and whether a record is sufficient for a given purpose is determined by the party asking and by a clinician, not by the person keeping it.
