Tetanus booster in Belgium: the 10-year rule explained

In Belgium the adult tetanus booster is an injection of dTpa (diphtheria, tetanus and reduced-dose pertussis) to be repeated every 10 years, according to the Superior Health Council. So it is not a tetanus-only vaccine: all three diseases are boosted in a single shot, and pertussis rides along.
On top of that baseline rule, two situations change the timing: a wound, and a pregnancy. Here is what the official Belgian sources say, and what they do not say.
- The baseline rule: a dTpa booster every 10 years in adulthood, as a single injection covering all three diseases.
- It is not a tetanus-only vaccine: the Superior Health Council asks for the combined one, so that adult pertussis coverage keeps rising.
- A wound can bring the booster forward: past 5 years for an at-risk wound, past 10 years for a clean one.
- During pregnancy: one dose of dTpa at every pregnancy, ideally between weeks 24 and 32.
- Your last booster is recorded somewhere: MaSanté shows the data the regional registries pass on to it, with coverage that varies by region.
Why do you need a booster, and what is tetanus exactly?
Tetanus is a serious, often fatal infectious disease that attacks the nervous system: it causes intense muscle contractions that can lead to death by asphyxia if the respiratory muscles are affected. According to vaccination-info.be, 40 to 50 % of people who contract tetanus die from it.
It is caused by a toxin from the bacterium Clostridium tetani, whose spores live in soil and in animal and human faeces. Those spores are extremely heat-resistant and survive for years in the environment. Tetanus enters the body through a contaminated wound or cut, and it is not contagious: it does not spread from person to person.
The most counter-intuitive point: having had tetanus does not protect you against catching it again. That is why vaccination has to be maintained throughout life, and not only in childhood.
How often do you need a booster in Belgium?
Every 10 years. The CBIP/BCFI Repertoire, which carries the position of the Superior Health Council (CSS/HGR Avis 8819, 2013), states that a booster should in principle be given every 10 years. The adult page of vaccination-info.be says the same and adds the detail that matters: the booster against all three diseases is given in a single injection.
The Council explicitly recommends the combined dTpa vaccine rather than a tetanus/diphtheria-only one, precisely so that pertussis vaccination coverage keeps rising in the adult population. It is a public-health choice: pertussis hitches a ride on the tetanus appointment.
The reasoning also holds because protection against pertussis erodes quickly: the studies cited by the Council show a marked decrease, or even a disappearance, of post-vaccination antibodies within 5 to 10 years of the last dose.
The 10-year rule applies to older people too: the immunological efficacy of the pertussis vaccine after 65 has been demonstrated, even if its duration of protection is shorter than for diphtheria and tetanus.
What if my last booster was far more than 10 years ago?
The catch-up depends on how late you are, and it is not always a single dose. For an adult whose primary childhood series was properly completed: if the last dose was 10 to 20 years ago, one dose of dTpa is enough; if it was more than 20 years ago, two are needed, 6 months apart.
If instead the primary vaccination is unknown or incomplete, it is no longer a catch-up but a full schedule: 2 injections 4 to 6 weeks apart, then a 3rd injection 6 to 12 months later.
In other words, "I no longer know" is not treated as "it is probably fine": the official sources treat an unknown status as a status to be rebuilt from scratch. Your doctor decides which case you fall into.
I hurt myself: what do the official rules say?
A wound switches the timing to a second, stricter grid. CBIP/BCFI reproduces the official Belgian wound-management table (Table 12c), explicitly sourced from Avis CSS 8819. It crosses two things: the type of wound and the date of your last dose.
A wound "at risk of tetanus" is officially defined as: a contused or bruised wound, a bite, a penetrating wound (wood splinters or thorns), a wound contaminated by soil or animal droppings, or a wound neglected for more than 6 hours. Everything else is classified as a superficial and clean wound.
| Wound type | Last dose | What the official table provides |
|---|---|---|
| Clean or at-risk | Less than 5 years | Nothing to do. |
| Clean and superficial | 5 to 10 years | Nothing to do. |
| At-risk | 5 to 10 years | 1 dose of vaccine. |
| Clean and superficial | 10 to 20 years | 1 dose of vaccine. |
| At-risk | 10 to 20 years | 1 dose of vaccine + specific immunoglobulins. |
| Clean and superficial | More than 20 years | 2 doses of vaccine 6 months apart. |
| At-risk | More than 20 years | 2 doses 6 months apart + specific immunoglobulins. |
| Clean and superficial | Unknown or uncertain status, or incomplete primary series | Complete the primary vaccination series. |
| At-risk | Unknown or uncertain status, or incomplete primary series | Complete the primary vaccination series + specific immunoglobulins. |
This table is a re-presentation of the official one, not medical advice: the decision belongs to the clinician who sees the wound.

If you are injured, see a doctor or an emergency department promptly, without waiting until you have tracked down the date of your last booster.
What are the immunoglobulins in that table for?
Tetanus immunoglobulins do not replace the vaccine: they are added to it. The Council recommends them as prophylaxis in the case of a soiled wound in someone who is unimmunised or whose immune status is uncertain, and they are given at the same time as a dose of active vaccine, never on their own.
One Belgian particularity is worth knowing: there is no longer any product containing tetanus immunoglobulins alone marketed in Belgium. It has to be imported from abroad by the pharmacist, on presentation of a named prescription and a declaration from the doctor.
In practice, tetanus immunoglobulins are also available in hospital emergency departments, which explains why an at-risk wound with a doubtful vaccination status calls for prompt care rather than a trip to the pharmacy.
Is the booster different during pregnancy?
Yes, and it is the only situation where the booster repeats without looking at the 10 years. The Superior Health Council recommends one dose of dTpa at every pregnancy, ideally between gestational weeks 24 and 32, that is from the end of the 2nd trimester into the 3rd.
The point is not to protect the mother against tetanus: pertussis is the target. Vaccinating the pregnant woman lets her pass her pertussis antibodies to the fetus across the placenta, which protects the newborn from birth until its own vaccination series takes over. Pertussis is indeed a very severe disease in very young infants.
The dose is repeated at every subsequent pregnancy, not just the first, because antibody levels fall rapidly after vaccination and each fetus needs its own transfer of protection.
On safety, studies across several countries covering more than 100,000 pregnant women showed no significant increase in serious adverse effects for the mother, the fetus or the newborn. Pregnancy is not a contraindication to the combined diphtheria-tetanus-pertussis vaccine. The Council also recommends primary tetanus vaccination during pregnancy for women with no proof of prior vaccination.
Where do you get it, and what does it cost?
The adult dTpa vaccine is a prescription-only medicine (marked "R/" in the CBIP/BCFI Repertoire), so you need a prescription. It is most often given at the GP surgery, but vaccination-info.be specifies that administration can take place during a medical consultation, at hospital or in an approved centre.
Two vaccines are available in Belgium for this adult booster: Boostrix (GSK) and Triaxis (Sanofi Belgium), both single-dose 0.5 ml pre-filled syringes for intramuscular injection. The prices listed in the CBIP/BCFI Repertoire (pricing basis as at 01/10/2025) are 25.11 EUR for the Boostrix syringe and 33.77 EUR for the Triaxis one.
Boostrix is reimbursed by INAMI/RIZIV "under certain conditions", in reimbursement category B, the category INAMI reserves for pharmaceutical specialities that are therapeutically important.
Do not confuse two circuits. For certain target-group indications (for example a teenager over 16 who missed the dose scheduled at 14-16 for a documented medical or social reason, or family members, future parents and siblings around a pregnancy who are not up to date), Boostrix reimbursement runs through INAMI Chapter IV (paragraph 5050000).
That route requires prior medical authorisation via a formal request form, a minimum interval of one month since any previous dT vaccination, and a maximum of one package per beneficiary; the co-payments quoted there are 6.56 EUR, or 3.91 EUR with increased intervention (BIM). Those amounts apply to that circuit alone and are not the price of a routine 10-year booster.
Separately, for certain target groups, notably pregnant women between weeks 24 and 32 and the doses in the child and adolescent schedule, Boostrix is distributed free of charge by the Communities, outside the pharmacy/INAMI circuit.
None of the official sources reviewed publishes the net amount left to pay for a routine booster after reimbursement: your mutuality or your pharmacist will confirm that figure.
Do you need a fresher booster before travelling?
None of the official Belgian sources reviewed (vaccination-info.be, Sciensano, the Superior Health Council, laatjevaccineren.be, CBIP/BCFI, INAMI/RIZIV) provides for a travel-specific shortened interval for tetanus. So, as far as we could establish, there is no official rule along the lines of "you need a booster less than X years old before you leave". The applicable rule remains the 10-year one, the same in Belgium as anywhere else.
That does not make the question pointless: a departure is precisely a good moment to check the date, since tetanus enters through a soiled wound and a travel-medicine consultation reviews your vaccination status anyway. But if you read a shorter, travel-specific interval somewhere, know that we could not find it in the official Belgian sources.
Where can you see the date of your last booster?
MaSanté.be is the federal portal that lets citizens view and download their own vaccination data, that is, see which vaccines they received. One important nuance: MaSanté stores nothing itself, it pulls the data from the regional registries and networks.
What you see there therefore depends on what was actually entered into your region's system, and coverage differs between Flanders, Wallonia and Brussels, and the German-speaking Community.
In Flanders the registry is Vaccinnet, described by eHealth as a system for ordering and recording vaccination products for healthcare providers, allowing them to consult and record their patients' vaccinations: it is built for the clinician rather than as a citizen-facing desk.
On the Walloon and Brussels side, the Vaccicard tool was being connected to the new Vaccinnet 2.0 system at the time of this research, with the aim of one day letting you look up your vaccination status whichever Belgian region you were vaccinated in; but at this stage Vaccicard data does not yet appear inside MaSanté.
If you find nothing anywhere, the official answer is not an administrative trick but a clinical rule: an unknown or uncertain status is treated as a vaccination to be rebuilt, with a full primary series, plus immunoglobulins on top in the case of an at-risk wound. Your GP remains the best starting point, since they recorded most of your doses in the first place.
The real problem with the tetanus booster: ten years is a long time
The rule is simple, applying it much less so: nobody spontaneously remembers an appointment set ten years earlier, and it is often in an emergency department, with a cut hand, that you realise you no longer know the date. A digital record like emmunity keeps that date, works out the next due date and warns you before it arrives, for you and for the people around you.
Frequently asked questions
How often do you need a tetanus booster in Belgium?
Every 10 years, as a combined dTpa vaccine (diphtheria, tetanus, reduced-dose pertussis) given in a single injection. That is the rule carried by the CBIP/BCFI Repertoire from Avis CSS 8819, and by the adult page of vaccination-info.be. The Superior Health Council explicitly asks for the combined vaccine rather than a tetanus/diphtheria-only one, so that pertussis coverage rises among adults: protection against pertussis erodes within 5 to 10 years. The 10-year rule applies after 65 as well. Two situations change it: a wound, which can bring the booster forward, and a pregnancy, where one dose is recommended every time, ideally between weeks 24 and 32.
I hurt myself, do I need another booster?
It depends on the wound and on the date of your last dose. The official table carried by CBIP/BCFI distinguishes a clean, superficial wound from an "at-risk" one: a contused or bruised wound, a bite, a penetrating wound from splinters or thorns, a wound contaminated by soil or animal droppings, or a wound neglected for more than 6 hours. For a clean wound, a booster is provided for if your last dose was more than 10 years ago. For an at-risk wound, from more than 5 years. Beyond 10 years with an at-risk wound, or if your vaccination status is unknown or incomplete, the table adds specific immunoglobulins alongside the vaccine. See a doctor or an emergency department promptly: the clinician who sees the wound decides, not this table.
Is the booster reimbursed, and what does it cost?
The prices listed in the CBIP/BCFI Repertoire (basis as at 01/10/2025) are 25.11 EUR for the Boostrix pre-filled syringe and 33.77 EUR for the Triaxis one. Boostrix is reimbursed by INAMI/RIZIV "under certain conditions", in category B, the one for therapeutically important specialities. Watch out for a common trap: the co-payments of 6.56 EUR and 3.91 EUR (increased intervention) that circulate belong to the Chapter IV circuit, reserved for specific target groups with prior medical authorisation, and not to the routine 10-year booster. None of the official sources reviewed publishes the net amount left to pay for that routine booster: your mutuality or your pharmacist will confirm it.
Where can I see the date of my last booster?
On MaSanté.be, the federal portal that lets you view and download your vaccination data. MaSanté stores nothing itself: it pulls the information from the regional registries, so what you see depends on what was entered in your region, and coverage differs between Flanders, Wallonia and Brussels, and the German-speaking Community. In Flanders the registry is Vaccinnet, designed for healthcare providers. On the Walloon and Brussels side, the Vaccicard tool was being connected to Vaccinnet 2.0 at the time of this research, but its data does not appear in MaSanté yet. If you find nothing, your GP remains the best starting point; failing that, the official sources treat an unknown status as a vaccination to be rebuilt.
