Keeping Your Vaccination Record Digitally — Why the Switch Pays Off and What to Watch Out For

What a complete vaccination record contains

A vaccination record documents which vaccination you received and when. For an entry to remain usable years later, a date and an abbreviation are not enough. A complete record covers five details per entry:

• Date of vaccination. The date places the entry in chronological order. It is the basis of every later assessment by a doctor.
• Vaccine name. The trade name identifies the specific product. It shows which pathogens the dose was directed against — combination vaccines cover several diseases in a single injection.
• Batch number. The batch number (also called the "lot") identifies the production unit of the vaccine. It matters for traceability, for example in product recalls or in reports to medicines authorities.
• Disease or antigen. This states what was vaccinated against — tetanus, measles or hepatitis B, for example. With combination vaccines, all components included belong here.
• Vaccinating provider. Practice stamp, pharmacy, occupational health physician, travel clinic or hospital. This detail makes the entry verifiable and shows you later where you can follow up.

Useful, though not standard everywhere: the dose number within a vaccination series (e.g. "2nd dose") and the country in which the vaccination was given. Both make later assessment considerably easier, especially if your vaccination history is spread across several countries.

Why the yellow paper booklet reaches its limits

The yellow vaccination booklet has worked for decades — but it has structural weaknesses.

It gets lost

A paper document exists exactly once. House moves, water damage, a change of practice: a lost vaccination record means losing the entire documented vaccination history. As a rule, there is no central copy. Medical files are also subject to retention periods, which differ in length from country to country.

It becomes illegible

Many entries consist of a stamp and a handwritten note. Stamp ink fades, handwriting is ambiguous, stickers come loose. Batch numbers are particularly vulnerable because they are usually stuck in as a small adhesive label. After twenty years, some entries are often only partly decipherable.

The documentation is scattered

A typical vaccination history is created in many places: the paediatric practice, the GP, occupational health, travel medicine, the pharmacy, the hospital. If you change practice, part of the information stays behind in the old archive. Anyone who has lived in several countries often has several records in several languages and formats — sometimes with different names for the same vaccine.

When travelling, you need it exactly when it isn't with you

The paper record is only available where you physically carry it. During short-notice travel preparation or a medical consultation abroad, that is often not the case.

Vaccination record lost — how to reconstruct your vaccination history

A lost vaccination record is not a final loss of data. The information usually still exists — just scattered. Work through it systematically:

1. GP practice. Your current practice normally keeps its own vaccination documentation in the patient file. Ask for a printout of the documented vaccinations, not just for verbal information.
2. Former practices and the paediatric archive. Childhood vaccinations make up the largest part of a vaccination history. Even if the practice was handed over or closed, there is often a successor or an archive. Ask specifically about the retention of old files.
3. Occupational health physician or occupational health service. In healthcare work, in laboratories or in field service, vaccinations were often given and documented by occupational health.
4. Travel medicine centres. Tropical medicine institutes, vaccination centres and travel medicine clinics keep their own records. If you were vaccinated before a long-haul trip, the most complete entries — batch numbers included — are often found there.
5. Pharmacies and vaccination centres. In some countries and regions, pharmacies vaccinate. Documentation is created there too.
6. Your own paperwork. Invoices, health insurance statements, school documents, old travel documents and photos of the record can supply dates that would otherwise be lost.

If gaps remain after this search, that is a medical matter. One option that doctors decide on case by case is measuring antibody titres in the blood. Whether such a test is useful depends on the vaccination in question — it is not informative for all vaccinations and not indicated in every case. Settle this in the consultation, not on your own.

The basic rule matters: document gaps as gaps. An uncertain entry recorded as certain is worse than an openly marked gap in knowledge. Medical staff can work with an honestly flagged uncertainty — not with an incorrect statement.

Boosters: recommendations are national, not universal

Vaccination recommendations do not apply uniformly worldwide. They are issued by national expert bodies and revised regularly. For the German-speaking countries these are:

• Switzerland: The Federal Office of Public Health (Bundesamt für Gesundheit, BAG/FOPH) publishes the Swiss vaccination schedule together with the Swiss Federal Commission for Vaccination Issues (Eidgenössische Kommission für Impffragen, EKIF).
• Germany: The Standing Committee on Vaccination (Ständige Impfkommission, STIKO) at the Robert Koch Institute issues the vaccination recommendations.
• Austria: The National Immunisation Board (Nationales Impfgremium) draws up the Austrian vaccination schedule.

These bodies differ in the details: which vaccinations are recommended, for which groups, at which intervals and from which age. Anyone crossing a national border may find that a vaccination series regarded as complete in their country of origin is assessed differently in their new country of residence.

That is why this article deliberately names no intervals and no age specifications. What counts is always the currently valid national vaccination schedule of your country of residence, combined with a medical assessment of your personal situation. Pre-existing conditions, occupation, pregnancy and planned travel can change the recommendation in an individual case.

In practice this means you need two things. First, complete, up-to-date documentation of the vaccinations you have had so far. Second, an appointment at which this documentation is checked against the applicable vaccination schedule. This is exactly where a digital vaccination record comes in: LogYourHealth stores your entries in a structured form and points out upcoming boosters according to your country's recommendation — the decision still rests with your doctor.

Travel: when proof is required

Some countries require proof of certain vaccinations on entry. The requirements depend on the destination country, in part also on the route and on the country you are entering from. They change and can be adjusted at short notice.

A standardised format exists for international proof, the WHO "International Certificate of Vaccination or Prophylaxis" — the classic yellow record in its travel form. Certain proofs are still accepted only on paper, with the stamp and signature of the vaccinating provider. So a digital vaccination record does not necessarily replace that document at the border; it ensures that you have your complete vaccination history to hand at any time.

Plan travel medicine advice well in advance. The reason is organisational: some vaccinations consist of several doses over a longer period, and individual vaccines are only available at specialised centres. You will find current entry requirements at the relevant embassy and in the travel advice of your foreign ministry.

Guide: digitising the paper record in a structured way

Digitising does not just mean photographing. A photo is a backup, not a usable data basis. Work through it in this order:

1. Gather all sources. Collect every record, supplementary sheet, loose insert and practice printout in one place. Only then start.
2. Scan everything. Scan or photograph every page — including apparently blank ones. Use good, even light without flash, lay the record flat and photograph it straight from above. Save the images as PDF or at high resolution. This scan is your fallback if a transferred entry is later called into question.
3. Record chronologically. Transfer the entries from oldest to newest. The chronological order reveals duplicates and missing series that stay invisible if you work unsystematically.
4. Fill in all five fields per entry. Date, vaccine name, batch number, disease/antigen, vaccinating provider. Better to leave a field empty than to guess.
5. Flag what is illegible, don't interpret it. If a digit is unclear, note it as uncertain — for example "date of vaccination 03.0?.1998, illegible". If the vaccine name cannot be deciphered, record what is legible. Avoid conclusions along the lines of "it will have been tetanus".
6. Document gaps explicitly. Note periods without entries as open items. Add which source you still want to ask about them.
7. Link the original scan to the entries. That way medical staff can check a disputed entry directly against the image. In LogYourHealth you store the scans together with the structured entries.
8. Keep the paper. The original record remains the document of proof. Continue to keep it and have new vaccinations entered in it.

Data protection: vaccination data is health data

Vaccination data belongs to the specially protected categories of personal data. The Swiss Data Protection Act (revDSG) and the European GDPR both place health data in a separate, more strictly protected category. For you, this has practical consequences when choosing where to store it.

Check before using a digital service:

• Server location. Where is the data physically stored? Locations in Switzerland or in the EU/EEA fall under the legal frameworks named above.
• Encryption. Is data encrypted in transit and at rest?
• Access and disclosure. Who has access? Is data passed on to third parties, analysed or used for advertising? The privacy policy must answer this clearly.
• Export and deletion. Can you export your data in full at any time and delete your account? A service without an export function creates a new dependency.
• Control over sharing. You decide who gets to see your data — not the provider.

A note on cloud storage: a scan of your vaccination record in a general photo or file service is backed up, but it is unstructured and often less strictly protected than in a service designed for health data. Above all, it is not searchable and cannot be checked against a vaccination schedule.

Conclusion

A digital vaccination record solves three problems at once: it is loss-proof, permanently legible, and it brings together scattered entries from several practices and countries. Most of the work lies in the one-off, careful initial entry — chronological, complete, with gaps honestly flagged. What follows after that is just upkeep.
