If you’re planning a trip to parts of Asia, Africa, or Latin America, chances are you’ve been advised to get protected against typhoid fever. But with so much conflicting information online, it’s easy to feel uncertain about what the vaccine involves, how effective it is, and what side effects you might experience.

At Eltham Pharmacy, we regularly support London travellers via our travel clinic, and we hear many of the same concerns time and time again. That’s why we’re here to clear up the confusion and set the record straight.

Here are five of the most common myths about the typhoid vaccine – debunked.

Myth 1: “You don’t need the typhoid vaccine unless you’re travelling somewhere rural”

Reality: Typhoid fever doesn’t just affect those trekking through remote villages. It’s caused by the bacterium Salmonella typhi, which is spread through contaminated food and water – something you can encounter even in major cities with poor sanitation or unreliable water supplies.

Whether you’re heading to bustling Delhi, urban Lagos, or the outskirts of Lima, the risk is still there. Restaurants, street vendors, or even ice in your drink can be potential sources of infection.

Getting vaccinated is one of the most effective ways to reduce your risk of serious illness, no matter your itinerary.

Myth 2: “The side effects of typhoid immunisation are too risky”

Reality: Like all vaccines, the typhoid vaccine may cause some side effects, but in the vast majority of cases, they are mild and short-lived.

Typical side effects of typhoid immunisation include:

• –> A sore or red arm where the injection was given

• –> Mild fever

• –> Tiredness

• –> Headache or general aches

These symptoms usually settle within a day or two and can be managed with rest and paracetamol. Serious side effects are extremely rare, and the vaccine has been proven safe in countless travellers worldwide.

The far greater risk is travelling unprotected and potentially contracting typhoid fever – a disease that can lead to hospitalisation or worse if untreated.

Myth 3: “The vaccine guarantees I won’t get typhoid”

Reality: While the typhoid vaccine is highly effective, no vaccine offers 100% protection. The injectable vaccine offers protection in around 70–80% of cases, while the oral version provides slightly lower protection and requires multiple doses.

That’s why the vaccine should always be combined with sensible food and water precautions:

• –> Only drink bottled or purified water

• –> Avoid raw or undercooked foods

• –> Be cautious with ice and salad

• –> Practise good hand hygiene

Together, these measures give you the best possible defence against infection during your trip.

Myth 4: “You only need the typhoid vaccine once in your life”

Reality: Protection from the typhoid vaccine doesn’t last forever. Depending on which vaccine you receive, you may need a booster every few years.

• –> Injectable vaccine (Typhim Vi): Usually lasts for 3 years

• –> Oral vaccine (Vivotif): Protection lasts around 5 years

If you travel frequently or last had the vaccine several years ago, it’s important to check your records. At Eltham Pharmacy, we’ll review your travel history and ensure you’re up to date with boosters and other essential travel jabs.

Myth 5: “You can only get the typhoid vaccine from your GP”

Reality: While some GP surgeries do offer travel vaccinations, many do not – and NHS supply is often limited to just a few vaccines. That’s where private travel vaccine clinics like ours come in.

At Eltham Pharmacy, we provide:

• –> Flexible appointments – including evenings and weekends

• –> Same-day or next-day bookings
