Lost your vaccination record? What to do in Belgium

A lost vaccination card is not a permanent loss in Belgium: your vaccinations are kept in several official registries (the regional registries you view through MaSanté, your medical record, school, occupational medicine, the pharmacy). Losing the paper card is more common than you would think. Here is every lead to recover them, in the most effective order.

Key takeaways

Start with MaSanté ("My vaccines"): web portal (eID, itsme) or official app (itsme); the app shows no vaccination data from the Walloon (RSW) and Brussels (RSB) health networks.
In Wallonia and Brussels, the regional patient portal (Réseau Santé Wallon, Brussels Health Network) also shows your vaccinations; in Flanders, the online route is the federal portal (mijngezondheid.belgie.be).
School (CLB/PSE), occupational medicine and the pharmacy are often-forgotten sources.
Your GP remains the reference, and can issue you a new card.
Once recovered, keep it digital so you never have to do this again.

Start with MaSanté, the federal portal

Log in at masante.belgique.be with your eID or itsme, then open "Ma santé" → "Mes vaccins" (My vaccines): you will see the electronically registered vaccinations, injection by injection.

There is also an official mobile app (MaSanté in French, MijnGezondheid in Dutch; iOS and Android, itsme login). The app, however, shows no vaccination data from the Walloon (RSW) and Brussels (RSB) health networks: use the web portal in that case (limit as read on 10 October 2026).

On MaSanté, your children's data is visible until they turn 16; in Wallonia and Brussels, access to a child's record follows the regional health network's own procedure (registration as legal representative; between 13 and 16, no online parental access on those networks).

MaSanté stores nothing itself: it reads the data where it is kept, region by region.

The regional portals, region by region

2006

The Vaccinnet registry has run since

In Wallonia, the Réseau Santé Wallon patient portal gives access to your shared record, vaccinations included. In Brussels, you view your vaccinations on the Brussels Health Network (Réseau Santé Bruxellois) patient portal, where they are published progressively, according to the Brussels administration Vivalis. In Flanders, the online route the administration points to is the federal portal: mijngezondheid.be redirects to mijngezondheid.belgie.be, the Dutch-language version of MaSanté, which shows the Vitalink data.

In Flanders, children's vaccinations have been recorded digitally since the late 1990s and the Vaccinnet registry has run since 2006.

In Wallonia and Brussels, Vaccicard is now the reference platform for registering the vaccines given. In Brussels, registration through Vaccicard has been mandatory since January 2026, according to Vivalis and the Brussels Health Network. In Wallonia, the Vaccicard decree has been in force since 23 January 2026, but it defers the duty to register: Wallonia’s official website announces a 12-month transition.

Older vaccines will not be in there.

Ask your GP

Your family doctor keeps your Global Medical Record, which according to INAMI/RIZIV gathers your medical data. It may include old vaccinations that never made it into the electronic registries: ask. Your doctor can also consult the regional registries for you.

School may have the answer

Vaccinations given at school are logged by the CLB in Flanders and by the PSE services in the Wallonia-Brussels Federation. The Flemish decree on pupil guidance limits how long the CLB file is kept to a maximum of ten years after the last systematic contact or the last vaccination (until the age of 30 for pupils who finished their schooling in special education): after that, the file is no longer kept.

For the PSE services, integration into Vaccicard is announced by AVIQ, the Walloon agency (document of February 2025), with no official date. A valuable lead for teenage vaccines, as long as the file exists.

Vaccinated at work? Think occupational medicine

If you work in healthcare, hepatitis B vaccination has been mandatory for many roles since a royal decree of 1999, now part of the Code on well-being at work: you must prove sufficient immunity or be vaccinated, unless there is a contraindication. The vaccination is given by the occupational physician or by a doctor of your choice.

Two records exist. Your employer keeps your last three vaccination forms and must hand them to you when you leave the company. Your health file, which lists the date and nature of your vaccinations, is kept by the prevention service, internal or external, for at least fifteen years after you leave. You have the right to consult it: address your request to the occupational physician.

The pharmacy keeps a trace longer than you think

10 years

The Shared Pharmaceutical Record keeps vaccines

1 year

The term for other medicines

The Shared Pharmaceutical Record keeps dispensed vaccines for ten years, versus one year for other medicines. Your regular pharmacy can therefore find which vaccine was dispensed to you, and when.

Your health insurer, to cross-check dates

Vaccine reimbursements appear on your mutuelle / ziekenfonds statements. They are not proof of vaccination, but they help recover what and when, useful to corroborate the other sources.

Two special cases: polio and vaccines received abroad

Polio is the only legally mandatory vaccination in Belgium. Its certificate is handed to the municipal administration of the child’s place of residence, before 18 months of age. If it is lost, ONE advises contacting the vaccinator or the municipal administration of your place of birth: some communes keep a record in their archives.

If you were vaccinated abroad, bring your certificates to your Belgian doctor and ask whether they can register them: the official sources reviewed describe no procedure for citizens.

Found nothing at all? Your doctor will help you restart

If no source lets you rebuild your history, book an appointment with your doctor: they will work out how to get you back on track. Good to know: they can issue you a new vaccination card at your next vaccination.

Then never lose anything again: go digital

Once the information is recovered, a digital record spares you this treasure hunt forever, which is exactly what emmunity does: the whole family's vaccines in one place, with automatic reminders, available even offline.

Frequently asked questions

Are my COVID vaccines in MaSanté?

Yes, in principle: electronically registered COVID vaccinations appear under "My vaccines" on the MaSanté web portal, like other vaccinations. The mobile app, however, shows no vaccination data from the Walloon (RSW) and Brussels (RSB) health networks. COVID certificates can no longer be downloaded through MaSanté.

How far back does the online data go?

The electronic registries mostly cover recent vaccinations: in Flanders, children's vaccines have been recorded since the late 1990s and Vaccinnet has existed since 2006. For older vaccines, go through your doctor, school or occupational medicine.

Can I get a new paper card?

Yes. Your doctor can issue you a new vaccination card at your next vaccination and copy the recovered history into it.

I was vaccinated abroad: how do I add it to my Belgian record?

Bring your foreign certificates (date, country, product name, batch number if possible) to your Belgian doctor and ask whether they can register those vaccinations: the official sources reviewed describe no procedure for citizens.
