How often you should get the typhoid fever shot depends on which type of vaccine you receive — the injectable polysaccharide vaccine requires a booster every three years for those who remain at continued risk, whilst the oral live attenuated vaccine capsules also provide protection for up to three years and re-vaccination is recommended after this period for ongoing travellers. The typhoid fever shot is not a one-time vaccination, and anyone who travels regularly to typhoid-endemic regions needs to ensure their protection is kept current by receiving repeat doses within the recommended timeframe. Neither form of typhoid vaccine provides lifelong protection, which distinguishes typhoid from some other travel vaccines, making forward planning and regular review of your vaccination status an important part of travel health preparation for frequent visitors to high-risk destinations. At Perfect Meds, our expert pharmacists can assess your travel history, review your existing vaccination records, and advise on whether a typhoid fever shot is due ahead of your next trip, providing clear and personalised guidance in a single convenient appointment.

The typhoid fever shot should be repeated every three years for those who remain at continued risk of exposure, regardless of whether the injectable or oral form of the vaccine was used. The injectable polysaccharide vaccine is given as a single dose and provides protection for approximately three years, whilst the oral vaccine consists of three capsules taken on alternate days and also provides protection for up to three years in the UK. Both forms of the vaccine should be administered at least two weeks before potential exposure to allow the immune system to develop an adequate protective response. At Perfect Meds, our expert pharmacists can advise on which type of typhoid fever shot is most appropriate for your individual circumstances and ensure your protection is current before you travel.
The Importance of Typhoid Fever Vaccination
Typhoid fever is a systemic bacterial infection caused by Salmonella enterica serotype Typhi, a pathogen transmitted primarily through the consumption of food or water contaminated with the faeces of an infected person. It is a disease closely associated with inadequate sanitation infrastructure and limited access to clean water, making it endemic in many parts of South Asia, sub-Saharan Africa, Southeast Asia, and Central and South America — regions that collectively represent some of the most popular international travel destinations for UK residents. According to the World Health Organization, typhoid fever affects an estimated 11 to 21 million people globally each year, causing between 128,000 and 161,000 deaths annually, with the burden of disease falling disproportionately on children and young adults in low and middle-income countries.
The clinical presentation of typhoid fever typically develops one to three weeks after infection and is characterised by a sustained high fever, headache, abdominal pain, constipation or diarrhoea, and a general feeling of being severely unwell. Without prompt antibiotic treatment, typhoid fever can progress to serious and life-threatening complications including intestinal perforation, haemorrhage, and multi-organ failure. Of particular concern for travellers and clinicians is the emergence and spread of extensively drug-resistant (XDR) typhoid, a strain of Salmonella Typhi resistant to multiple first-line antibiotics that has been particularly prominent in Pakistan and is spreading to other regions, making prevention through vaccination increasingly important as a first line of defence.
The Two Types of Typhoid Fever Shot Available in the UK
In the UK, two distinct forms of typhoid vaccination are currently available, each with different characteristics, mechanisms of action, dosing schedules, and suitability criteria. A clear understanding of the key differences between the two vaccine types makes it significantly easier to determine which is the most appropriate option for a given traveller’s individual situation.
The Injectable Typhoid Vaccine
The injectable typhoid vaccine — most commonly available under the brand name Typhim Vi — is a polysaccharide vaccine administered as a single intramuscular injection, typically into the deltoid muscle of the upper arm. It works by exposing the immune system to a purified polysaccharide from the surface of Salmonella Typhi, stimulating the production of protective antibodies without the need for a live organism. The injectable vaccine begins to provide protection approximately two weeks after administration and is considered to offer protection for approximately three years, after which a booster is recommended for those who remain at continued risk.
The injectable vaccine is suitable for most adults and children aged two years and over, is generally well tolerated with a mild side effect profile, and does not contain live bacteria — making it safe for use in immunocompromised individuals and, following appropriate risk-benefit assessment, during pregnancy. It is available as a standalone vaccine or in combination with the hepatitis A vaccine (as Hepatyrix or ViATIM), making it a particularly practical option for travellers who require protection against both diseases simultaneously.
The Oral Typhoid Vaccine
The oral typhoid vaccine — available under the brand name Vivotif — consists of three capsules containing a live attenuated strain of Salmonella Typhi, taken on alternate days (days one, three, and five). It works by stimulating mucosal immunity in the gut, where Salmonella Typhi first establishes infection. Because it is a live vaccine, the oral typhoid vaccine is not suitable for immunocompromised individuals, those currently taking antibiotics, or pregnant women. It must be stored in the refrigerator, taken on an empty stomach, and administered strictly according to the alternate-day schedule to ensure adequate immune stimulation.
The oral vaccine provides protection for up to three years in the UK, after which re-vaccination with a further three-capsule course is recommended for those who remain at ongoing risk. Some travellers prefer the oral route for convenience or because they prefer to avoid injections, though the requirement for refrigeration, correct timing, and the interaction with antibiotics makes it less suitable for some individuals. A pharmacist at Perfect Meds can discuss the pros and cons of each option in the context of your specific health history and travel plans.
Choosing between the injectable and oral typhoid vaccine is a decision best made with expert guidance tailored to your individual health history and travel itinerary. Call us to book a consultation with Perfect Meds today and our expert pharmacists will help you identify the most appropriate option and get your typhoid vaccination arranged well ahead of your departure date.

Who Needs the Typhoid Fever Shot?
The typhoid fever shot is recommended for travellers visiting countries and regions where typhoid fever is endemic and where access to clean water and safe food preparation may be limited. This includes much of South Asia — particularly India, Pakistan, Bangladesh, and Nepal, which together account for a significant proportion of global typhoid cases — as well as large parts of sub-Saharan Africa, Southeast Asia, and Central and South America. Travellers visiting friends and relatives in these regions are at particular risk, as they are more likely to eat locally prepared food, drink water from local sources, and spend extended periods in environments where the risk of exposure to contaminated food or water is higher than in tourist hotels and restaurants.
Beyond travel, the typhoid vaccine is also recommended for laboratory workers who handle Salmonella Typhi professionally. In the UK, the vaccine is not part of the routine childhood immunisation schedule and is not available on the NHS for travel purposes, meaning that the vast majority of travellers will need to access it through a private travel clinic or registered pharmacy. Given that the injectable vaccine requires only a single dose and the oral course requires just three capsules over five days, typhoid vaccination is one of the more straightforward travel health preparations — provided sufficient time is allowed before departure for the immune response to develop.
How Soon Before Travel Should You Get the Typhoid Fever Shot?
Both forms of the typhoid fever shot should be administered or completed at least two weeks before potential exposure to allow sufficient time for the immune system to develop an adequate protective response. For the injectable vaccine, this means receiving the single injection at least two weeks before arrival in a typhoid-endemic region. For the oral vaccine, the three-capsule course must be completed at least two weeks before travel, meaning the first capsule should be taken no later than sixteen days before departure to allow the course to be completed and the two-week window to elapse.
Leaving typhoid vaccination until the last minute is a common mistake that can leave travellers either unprotected or with only partial protection at the time of departure. Ideally, a travel health consultation should be booked at least six to eight weeks before departure — this allows not only for typhoid vaccination but also for any multi-dose vaccine courses that may be required for the destination to be completed in full. If a departure date is approaching and vaccination has not yet been arranged, it is still worth booking as soon as possible — even a vaccination given slightly less than two weeks before travel will provide some degree of protection, and partial protection is considerably better than none.
Typhoid Fever and Drug Resistance
One of the most compelling arguments for maintaining up-to-date typhoid vaccination for travellers to high-risk regions is the growing global problem of antibiotic-resistant typhoid. Typhoid fever is treatable with antibiotics — historically, fluoroquinolones such as ciprofloxacin and third-generation cephalosporins have been the mainstay of treatment. However, the emergence and rapid international spread of multidrug-resistant (MDR) typhoid and, more recently, extensively drug-resistant (XDR) typhoid has significantly complicated the treatment landscape and underscored the importance of prevention.
XDR typhoid — defined as typhoid fever resistant to all first- and second-line antibiotics except azithromycin and carbapenems — was first identified in Pakistan in 2016 and has since spread to multiple countries. Cases of XDR typhoid in UK travellers returning from Pakistan have been reported, and the prospect of a traveller contracting a strain of typhoid that is extremely difficult to treat highlights the critical importance of pre-travel vaccination as a preventive measure. With drug-resistant typhoid strains now circulating in Pakistan and a growing number of other regions, keeping typhoid vaccination current before travel to these destinations has never been more critical.
Typhoid is just one of several serious health risks that travellers to high-risk regions need to be aware of, and knowing your full vaccination requirements before you depart is an essential part of responsible travel preparation. Enter your destination below to get an instant overview of the travel vaccinations and health precautions that may be recommended for your trip, including whether the typhoid fever shot should form part of your pre-travel health plan:
Food and Water Safety Alongside the Typhoid Fever Shot
Whilst the typhoid fever shot is an important and effective tool for reducing the risk of typhoid infection, neither the injectable nor oral vaccine provides 100% protection. The injectable polysaccharide vaccine is estimated to be approximately 55 to 72% effective against typhoid fever, and whilst this represents a meaningful and significant reduction in risk, it means that careful attention to food and water hygiene remains an essential complement to vaccination for any traveller visiting a typhoid-endemic region.
–> Drink only bottled, boiled, or chemically treated water — avoid tap water, ice in drinks, and unbottled water even when brushing teeth in high-risk destinations.
–> Eat only thoroughly cooked food that is served hot — avoid raw or undercooked meat, fish, and shellfish and exercise caution with buffet-style food that may have been standing for extended periods.
–> Avoid raw fruits and vegetables that cannot be peeled — if eating fresh produce, ensure it has been washed in treated water or peel it yourself immediately before eating.
–> Be particularly cautious with street food, locally prepared salads, and foods that may have been handled by multiple people before consumption.
–> Apply the practical principle of “boil it, cook it, peel it, or leave it” as a daily guide to food safety decisions in high-risk environments.
–> Wash hands thoroughly with soap and water before eating and after using the toilet — where soap and water are not available, use an alcohol-based hand sanitiser as a temporary measure, noting that hand sanitiser is not effective against all food-borne pathogens.
Typhoid Vaccine Safety and Side Effects
Both forms of the typhoid fever shot have well-established safety profiles and have been administered to large numbers of travellers worldwide over many years. The injectable polysaccharide vaccine is generally very well tolerated, with the most commonly reported reactions being mild and short-lived.
Common Side Effects of the Injectable Typhoid Vaccine
–> Soreness, redness, or mild swelling at the injection site — the most frequently reported reaction, typically resolving within two to three days without treatment.
–> Mild headache, fatigue, or low-grade fever in a proportion of recipients, usually resolving within 24 to 48 hours of vaccination.
–> Occasional mild nausea or muscle aches following vaccination, particularly in the day or two after the injection.
–> Serious allergic reactions are extremely rare — recipients should remain at the vaccination centre for at least 15 minutes after the injection so that any immediate reactions can be managed promptly.
Common Side Effects of the Oral Typhoid Vaccine
–> Mild gastrointestinal symptoms including nausea, abdominal discomfort, diarrhoea, or vomiting in a small proportion of recipients, which usually resolve quickly without specific treatment.
–> Occasional headache or skin rash reported by a small number of recipients following the oral course.
–> Serious adverse events associated with the oral vaccine are very rare, but as with all live vaccines, those who are immunocompromised should not receive the oral formulation.
The Typhoid and Hepatitis A Combination Vaccine
Travellers who require protection against both typhoid fever and hepatitis A, two diseases that share similar transmission routes through contaminated food and water, can access a combination vaccine that provides protection against both in a single injection. This combination vaccine is a highly practical option that eliminates the need for separate injections and can significantly simplify the pre-travel vaccination process, particularly for travellers visiting multiple high-risk destinations or those who have limited time before departure.
The combination vaccine contains the same typhoid polysaccharide antigen as the standalone injectable typhoid vaccine alongside an inactivated hepatitis A antigen, providing comparable efficacy for both diseases in a single dose. As with the standalone injectable typhoid vaccine, a booster for the typhoid component is recommended every three years for those at continued risk, whilst the hepatitis A component provides protection for approximately one year from a single dose — with a booster given six to twelve months later extending this to at least 25 years. A pharmacist at Perfect Meds can advise on whether the combination vaccine is the most appropriate option for your itinerary and help you plan a complete pre-travel vaccination schedule.
Anyone planning a trip to a typhoid-endemic destination should prioritise checking and updating their typhoid vaccination status as an essential part of their pre-travel health preparation.

Frequently Asked Questions
These answers to the most common questions about the typhoid fever shot are designed to help every traveller, from those booking their first vaccination to those returning for a repeat dose, make a well-informed and confident decision about their travel health.
Is the typhoid fever shot available on the NHS?
The typhoid vaccine is not routinely available on the NHS for travel purposes and must be obtained through a private travel clinic or registered pharmacy such as Perfect Meds. Laboratory workers who handle Salmonella Typhi professionally may be eligible for NHS-funded vaccination through their occupational health service.
Can children receive the typhoid fever shot?
Yes — the injectable typhoid vaccine is suitable for children aged two years and over, whilst the oral vaccine is licensed for children aged six years and over in the UK. Children travelling to typhoid-endemic regions are encouraged to be vaccinated, as they may be particularly vulnerable to severe illness and may be less able to consistently follow food and water hygiene precautions.
What happens if I miss the re-vaccination date for my typhoid shot?
If you have missed the three-year re-vaccination window and are planning to travel to a typhoid-endemic region, you should arrange a repeat dose of the typhoid vaccine as soon as possible and at least two weeks before departure. A single dose of the injectable vaccine or a fresh three-capsule oral course will re-establish protection — there is no need to treat a lapsed typhoid vaccination as equivalent to never having been vaccinated.
Does the typhoid fever shot protect against paratyphoid fever?
Neither the injectable nor the oral typhoid vaccine provides protection against Salmonella Paratyphi, which causes paratyphoid fever — a related but distinct illness with similar symptoms. Food and water hygiene precautions remain essential for reducing the risk of both typhoid and paratyphoid fever, as well as many other foodborne illnesses encountered in high-risk destinations.
Can I have the typhoid vaccine at the same time as other travel vaccines?
Yes — the injectable typhoid vaccine can be administered simultaneously with most other travel vaccines without any reduction in efficacy or increased risk of side effects, making it straightforward to combine with other required vaccinations in a single travel health appointment. The oral typhoid vaccine should not be taken at the same time as antibiotics or certain antimalarials — a pharmacist can advise on the optimal timing if you are taking these medications.
How effective is the typhoid fever shot?
The injectable polysaccharide typhoid vaccine is estimated to be approximately 55 to 72% effective against typhoid fever, providing meaningful but not complete protection — which is why food and water hygiene precautions remain essential alongside vaccination. The oral live attenuated vaccine has demonstrated similar efficacy in clinical studies, and both vaccines significantly reduce the risk of contracting typhoid fever compared to travelling unvaccinated.
Keep Your Typhoid Protection Current
The typhoid fever shot is one of the most important and straightforward travel health preparations for anyone visiting South Asia, sub-Saharan Africa, Southeast Asia, or other typhoid-endemic regions — and with protection lasting only three years, keeping it current through timely re-vaccination is an essential part of maintaining effective travel health cover for frequent travellers to these destinations. With the added challenge of drug-resistant typhoid strains making treatment increasingly difficult, prevention through vaccination has never been more important than it is today.
