Many travellers ask, “How long does typhoid vaccine last?” For most UK travellers, the practical answer is around three years. If you remain at risk of typhoid, current UK guidance recommends a booster vaccination—or a repeat three-capsule oral course—at three-year intervals.
That three-year interval applies after a single injectable typhoid vaccine and after a complete oral typhoid vaccine course. The vaccine does not suddenly “switch off” on the three-year anniversary, but you should not assume you are adequately protected for a new trip once your vaccination is out of date. A travel-health professional can review when you were vaccinated, where you are going and whether another dose is appropriate.
Typhoid vaccination is only one part of prevention. No typhoid vaccine gives complete protection, and current vaccines do not protect against most paratyphoid infections. Careful food, water and hand hygiene remain important even when your vaccination is up to date. You can also review the typhoid vaccine cost and booking guide or find a travel clinic near you if you need an individual assessment.
How Long Does Typhoid Vaccine Last?
For UK travellers, the practical answer is around three years. The NHS states that the typhoid vaccine lasts for three years, and TravelHealthPro advises reinforcing immunisation every three years for people who remain at risk.
The exact protection experienced by an individual can vary. Vaccine type, whether the full oral course was completed, age, health, immune response and the level of exposure can all matter. The three-year interval is therefore best understood as the point at which continued risk should trigger a review and, where appropriate, revaccination—not as a guarantee that every person has identical protection until a precise expiry date.
| Question | Current UK guidance |
| How long does the injected typhoid vaccine last? | Around 3 years. A further dose is advised at 3-year intervals when risk continues. |
| How long does the oral typhoid vaccine last? | After a complete oral course, revaccination is recommended at 3 years when risk continues. |
| Does the vaccine become useless on the exact 3-year date? | Protection does not behave like a switch, but an out-of-date vaccination should be reviewed before further risk. |
| Does a typhoid vaccine protect against paratyphoid? | Current vaccines are intended for typhoid. They do not provide reliable protection against most paratyphoid infection. |
| Are food and water precautions still needed? | Yes. Vaccination is not 100% effective, so hygiene precautions remain essential. |
Typhoid injection vs oral tablets: how long does protection last?
Both injectable and oral typhoid vaccines are used in the UK. Their administration is different, but current UK travel-health guidance uses the same three-year revaccination interval for people who remain at risk after either a single injection or a completed oral course.
| Feature | Injectable typhoid vaccine | Oral typhoid vaccine |
| How it is given | One injection for the primary vaccination | A course of 3 capsules taken on days 1, 3 and 5 |
| When protection is expected | Immune response develops after vaccination; injectable vaccination should ideally be given at least 2 weeks before exposure | Protection begins about 7–10 days after the third capsule; the course should be completed at least 1 week before travel |
| UK revaccination interval | Every 3 years if risk continues | A repeat 3-capsule course at 3 years if risk continues |
| Age and suitability | Product age limits and clinical suitability vary; injectable options can be used for younger children than the oral vaccine | Vivotif is a live oral vaccine licensed from age 5; it is not suitable for everyone |
| Important practical point | Useful when a single-dose appointment is preferred | Capsules must be completed correctly; some medicines and health conditions affect suitability |
For more detail on the capsule option, read the oral typhoid vaccine guide. The choice between oral and injectable vaccination should be based on age, timing, medical history, medicines, vaccine availability and clinical assessment—not only on a preference for tablets or injections.
When do you need a typhoid vaccine booster?
A typhoid booster should be considered when your last injectable dose or completed oral course was about three years ago and you will continue to have a meaningful risk of exposure. You do not need a booster simply because three years have passed if there is no current or planned risk; the decision is linked to your destination and itinerary.
A travel-health assessment may be particularly useful if you are:
· returning to a country or area where typhoid vaccination is recommended for your type of trip;
· visiting friends or relatives and staying in local communities for an extended period;
· travelling frequently or for a long time in places where sanitation and food hygiene may be poor;
· backpacking, working, volunteering or travelling in rural or remote settings;
· likely to eat in a wide range of local settings or have limited access to safe food and water; or
· unsure when your last typhoid vaccination was given or whether an oral course was completed correctly.
Country recommendations can change, and risk may vary within a country. Check the latest destination guidance and discuss your itinerary rather than relying on a previous trip or an old vaccine card alone.
You can start with the TravelJabs4U destination vaccine guide and then confirm the advice during a travel-health consultation.

Does the typhoid vaccine expire after three years?
People often ask whether the typhoid vaccine “expires.” Your vaccine record may show the date it was given, but immunity does not end at midnight exactly three years later. The three-year interval is the recommended point for reinforcing protection when exposure risk continues.
If your last dose was more than three years ago, do not assume that you are fully protected for a new high-risk trip. Arrange a risk assessment so a clinician can review your vaccination history, destination, departure date and whether an injectable booster or repeat oral course is suitable.
Similarly, do not arrange a booster solely because you are anxious about a date on a record. Revaccination should be connected to ongoing or renewed risk and your individual circumstances.
How do you know whether your typhoid vaccine is still in date?
Check the date of your last typhoid injection or the date you completed the oral course. Useful records may include:
· a vaccination card or travel-health record;
· your NHS App or GP vaccination record, where the information has been recorded;
· a record held by the pharmacy or travel clinic that vaccinated you;
· an occupational-health record; or
· a previous travel-clinic letter or receipt that identifies the vaccine and date.
If you cannot find reliable documentation, tell the travel-health professional. Where previous doses are not adequately documented, repeating vaccination may be considered after an individual risk assessment. Do not guess the date or record an estimated date as fact.
Can you get a typhoid booster earlier than three years?
Most travellers do not need routine typhoid revaccination earlier than the recommended three-year interval. However, vaccine decisions are made after a clinical risk assessment, so discuss your plans if your circumstances are unusual—for example, if your previous course may not have been completed correctly, your record is uncertain or you have a complex medical history.
Do not request extra doses simply to try to create “stronger” protection. Vaccination should follow current guidance and product information, and food and water precautions remain necessary regardless of the number of doses received.
Do you need a typhoid booster before every trip?
No. A booster is not automatically needed before every international trip. It may not be relevant for destinations where typhoid risk is low, and it may not be due if your previous vaccination remains within the recommended interval.
Before each trip, review:
1. the date and type of your last typhoid vaccination;
2. the countries and specific regions you will visit;
3. the length and style of the trip;
4. accommodation, planned activities and likely food and water exposure;
5. whether you are visiting friends and relatives or travelling beyond standard tourist routes; and
6. your age, medical history, medicines and previous vaccine reactions.
A broader vaccine review may also identify other boosters or travel-health needs. Read how long travel vaccinations last for an overview of common travel-vaccine durations.
How far before travel should you get a typhoid vaccine or booster?
Arrange a travel-health appointment at least four to six weeks before departure where possible. This gives time to review your full itinerary and any other vaccines or malaria-prevention needs, some of which may require more than one appointment.
For the injectable typhoid vaccine, UK guidance advises vaccination at least two weeks before potential exposure where possible. For the current oral Vivotif course, the three capsules are taken on days 1, 3 and 5, and the course should be completed at least one week before travel to a typhoid-risk area.
If you are travelling sooner, do not assume it is too late. Contact a travel-health professional promptly. The useful options depend on the time remaining, your destination, your medical history and the other health risks connected with your trip.
What if your last typhoid vaccine was more than three years ago?
If you are travelling to a place or in circumstances where typhoid vaccination is advised and your last vaccination was more than three years ago, arrange a travel-health review. You may be advised to have another injection or, if clinically suitable, a repeat oral course.
There is usually no need to panic or to assume you have no protection at all. The important point is that an out-of-date vaccination should not be treated as sufficient evidence of current protection for a new risk. A clinician can advise on the appropriate next step.
Does a previous typhoid infection mean you do not need another vaccine?
No. Previous typhoid infection does not guarantee complete, lifelong protection. Natural infection may provide only partial protection against reinfection, so vaccination may still be considered for future travel when the risk assessment supports it.
Tell the clinician about any previous typhoid or paratyphoid diagnosis, treatment, complications and available medical records. This information should be considered alongside your current itinerary and health.
How effective is the typhoid vaccine?
Typhoid vaccination reduces risk but does not provide complete protection. Effectiveness varies between vaccine types, studies and populations, and protection can be reduced when exposure is intense. This is why vaccination should be combined with careful food, water and hand hygiene.
The vaccine also does not reliably protect against most paratyphoid infection. Typhoid and paratyphoid can both be acquired through contaminated food and water, so the same practical hygiene precautions matter even after vaccination.
Food and water precautions still matter after vaccination
Whether your typhoid vaccine is new, still in date or recently boosted, continue to reduce exposure to contaminated food and water. Practical measures may include:
· washing hands with soap and safe water before eating and after using the toilet;
· choosing food that is thoroughly cooked and served hot;
· being cautious with raw foods, salads and food that may have been washed in unsafe water;
· using safe drinking water and checking the seal on bottled water;
· avoiding ice when the water source is uncertain; and
· following current destination-specific food and water advice.
These measures also help reduce the risk of paratyphoid and other food- and water-borne infections that are not prevented by the typhoid vaccine.
Who may need extra advice before choosing oral or injectable typhoid vaccine?
The oral vaccine is a live vaccine and is not suitable for everyone. It may not be appropriate during pregnancy, in people with certain immune-system problems or while taking some medicines. Antibiotics can interfere with the live oral vaccine, and timing around some antimalarial medicines may also need to be considered.
The injectable vaccine is non-live, but it also has age limits, contraindications and precautions. Tell the clinician about pregnancy, immune-system conditions, allergies, current illness, all prescription and non-prescription medicines, previous vaccine reactions and any uncertainty about your vaccination history.
The correct option is the one that is clinically suitable and can be completed in time—not simply the one that appears to last longer. Current UK guidance uses the same three-year revaccination interval for continued risk after either option.
What side effects can occur after a typhoid vaccine?
Side effects depend on the vaccine used. After an injectable typhoid vaccine, temporary pain, redness, swelling or firmness at the injection site can occur. Some people may also experience headache, tiredness, muscle aches, feeling unwell or fever. Oral vaccine side effects can include stomach symptoms, nausea, diarrhoea or headache.
Most reactions are mild and short-lived, but serious allergic reactions are possible after any vaccine and require urgent medical attention. Your vaccinator should explain expected effects, warning symptoms and what to do if you feel unwell.
For vaccine-specific safety information, follow the advice provided by your clinician and read the patient information leaflet supplied for the product you receive. You can also review the typhoid vaccine service page before booking.

How to book a typhoid vaccine review in the UK
A travel-health consultation can confirm whether your previous typhoid vaccination is still within the recommended interval and whether typhoid vaccination is relevant for your next trip. Bring any vaccination record you have and be ready to provide your full itinerary, departure date, trip duration, accommodation, planned activities, medical history and current medicines.
TravelJabs4U can help you find participating travel vaccination clinics and review current price information before arranging an appointment.

A booking or consultation does not mean that a particular vaccine will automatically be recommended or supplied. Final advice should follow an individual clinical assessment.
Conclusion
So, how long does typhoid vaccine last? For most UK travellers, the practical answer is around three years. For people who remain at risk, current UK guidance recommends reinforcing vaccination at three-year intervals after either one injectable dose or a completed oral course.
You do not need a typhoid booster before every trip, and the decision should not be based on the date alone. Check your vaccination record, review the latest advice for your destination and arrange an individual travel-health assessment if your vaccination is out of date, your records are unclear or your itinerary creates a renewed risk.
Even after vaccination, continue to follow careful food, water and hand-hygiene measures because typhoid vaccines are not completely protective and do not reliably protect against most paratyphoid infection.

Frequently Asked Questions
The typhoid vaccine generally provides protection for around three years. If you remain at risk, UK guidance recommends a further injectable dose or a repeat oral course at three-year intervals.
A booster is generally considered every three years when the risk of typhoid continues or returns. You do not need a booster automatically before every trip; the decision depends on your destination, itinerary and vaccination history.
After a complete oral typhoid vaccine course, current UK guidance recommends revaccination at three years for people who remain at risk. The booster is another complete three-capsule course.
Protection does not switch off on an exact date, but three years is the recommended revaccination interval when exposure risk continues. If your vaccination is older than this, arrange a travel-health review before relying on it for a new trip.
No. A booster is not needed before every trip. It may be advised if your previous vaccination is out of date and your destination or planned activities create a relevant risk.
Tell the travel clinic that your record is missing or uncertain. The clinician can review your history and travel risk; where previous vaccination cannot be adequately documented, repeat vaccination may be considered.
Arrange travel-health advice at least four to six weeks before departure where possible. Injectable typhoid vaccination should ideally be given at least two weeks before exposure, while the oral course should be completed at least one week before travel.
Typhoid is one of the travel vaccinations that may be available free through the NHS following a travel-risk assessment. Availability and appointment arrangements vary, so check with your GP practice or use a private travel clinic if needed.
No. Typhoid vaccines do not provide complete protection and do not reliably protect against most paratyphoid infection. Continue to follow careful food, water and hand-hygiene advice.
