Quick Answer
Both oral and injected typhoid vaccines help reduce your risk of typhoid fever when travelling to higher-risk areas. The injected vaccine is a single-dose option, while the oral vaccine is taken as capsules over several days. The best choice depends on your age, medical history, travel date and suitability.
Typhoid fever is a bacterial infection usually spread through contaminated food or water. It is more common in parts of Asia, Africa, Central America and South America, particularly where sanitation and food hygiene may be poor.
Vaccination is recommended for many travellers visiting areas where typhoid is a risk. However, people are often unsure whether to choose the oral vaccine or the injected vaccine.
Both options can be useful, but they are not suitable for everyone. A travel-health professional can help you choose the safest and most practical option for your trip. You can learn more about available options on the Typhoid Vaccine page.
What Is Typhoid Fever?
Typhoid fever is caused by the bacterium Salmonella Typhi. It can spread when food or water is contaminated, especially in places where clean water and sanitation are limited.
Symptoms can include a high temperature, headache, tiredness, stomach pain, diarrhoea or constipation. If untreated, typhoid can lead to serious complications.
Vaccination reduces your risk, but it does not provide complete protection. You should still follow careful food and water hygiene while travelling. For broader protection advice, visit the Travel Vaccinations page.
Who Should Consider a Typhoid Vaccine?
You may need a typhoid vaccine if you are travelling to a country or region where typhoid is common, especially if you will eat local food, visit rural areas or stay with friends and family.
It may also be important for backpackers, long-stay travellers, aid workers, business travellers visiting remote areas and people travelling to South Asia, including India, Pakistan or Bangladesh.
Your recommendation depends on the destination, itinerary, length of stay, accommodation and previous vaccination history. A consultation at the Hemel Hempstead Travel Clinic can help assess your needs.
What Is the Injected Typhoid Vaccine?
The injected typhoid vaccine is given as a single injection, usually into the upper arm.
It is often convenient because only one appointment is needed. This can be helpful for travellers who are short on time or prefer not to manage a capsule schedule.
The injectable vaccine is suitable for many adults and children from 2 years of age. Protection is not immediate, so it is best to arrange it before travel rather than at the last minute.
Possible side effects are usually mild and may include soreness, redness or swelling at the injection site, headache, tiredness or mild fever.
What Is the Oral Typhoid Vaccine?
The oral typhoid vaccine is taken as capsules over several days.
It may be preferred by people who want to avoid an injection, but it requires careful timing. The capsules must be taken exactly as instructed to provide the best protection.
The oral vaccine is a live vaccine, so it is not suitable for everyone. It may not be appropriate for people with a weakened immune system, some medical conditions or certain medicines.
It is also not suitable for younger children who cannot swallow capsules properly.
Oral vs Injected Typhoid Vaccine: Main Differences
The main difference is how the vaccine is given. The injected vaccine is a single dose, while the oral vaccine is a short course of capsules.
Feature | Injected typhoid vaccine | Oral typhoid vaccine |
How it is taken | Single injection | Capsules over several days |
Convenience | Simple one-visit option | Requires correct timing |
Age suitability | From 2 years for licensed use | From 5 years for licensed use |
Type | Inactivated vaccine | Live vaccine |
Suitability | Suitable for many travellers | Not suitable for some immune conditions |
Best for | Travellers wanting a simple appointment | Travellers who can follow capsule instructions carefully |
Neither option is automatically better for everyone. The right choice depends on the traveller.
Pros and Cons of the Injected Vaccine
The injected typhoid vaccine is simple and convenient because it is usually completed in one appointment.
It may be a better option for people who are travelling soon, younger children aged 2 and above, or anyone who may struggle to complete an oral capsule course correctly.
The main downside is that some people dislike injections. Mild arm soreness, redness or tiredness can occur, but these effects usually settle quickly.
Pros and Cons of the Oral Vaccine
The oral vaccine may appeal to travellers who prefer capsules instead of an injection.
However, it needs more planning. The capsules are taken on specific days, and missed or incorrectly timed doses may reduce protection.
Because it is a live vaccine, it may not be suitable for people with weakened immunity or certain medical conditions. It can also be affected by some medicines, so a travel-health consultation is important before choosing this option.
Do Typhoid Vaccines Give Complete Protection?
No typhoid vaccine gives complete protection. Even after vaccination, travellers should still be careful with food and water.
Choose food that is freshly cooked and served hot. Drink bottled, sealed or boiled water where needed, and avoid ice if you are unsure about the water source.
Be cautious with salads, raw foods, unpeeled fruit, undercooked seafood and food that has been left uncovered.
Vaccination lowers risk, but hygiene precautions remain essential.
Which Typhoid Vaccine Should You Choose?
The best typhoid vaccine depends on your age, health, medicines, destination and how soon you are travelling.
The injected vaccine may suit you if you want a simple single-dose option or are travelling soon. The oral vaccine may suit some travellers who prefer capsules and can follow the schedule correctly.
A travel-health professional can check whether either option is unsuitable for you and confirm whether you need other vaccines, such as Hepatitis A, Hepatitis B or DTP.

People Also Ask
Is the oral typhoid vaccine better than the injection?
Not necessarily. The oral vaccine may suit some people, but the injection is often simpler because it is a single dose. Suitability depends on your age, health and travel plans.
How long before travel should I get a typhoid vaccine?
It is best to arrange travel-health advice at least 4 to 6 weeks before travel. Last-minute travellers should still seek advice.
Can I still get typhoid after vaccination?
Yes. Typhoid vaccines reduce risk but do not provide complete protection. Food and water hygiene remains important.
Is the oral typhoid vaccine suitable for everyone?
No. It is a live vaccine and may not be suitable for people with weakened immune systems or certain medical conditions.
