When I first decided to quit my job and sell everything I own to travel, one of the things I most worried about was vaccines.

I knew that I wanted to spend my time primarily exploring developing countries and I was concerned about exposing myself to dangerous tropical diseases. I was determined to ensure I received the most protection necessary without spending too much money or receiving vaccines that weren’t required. Despite all of this, I struggled to work out which vaccines I would need for which countries, how dangerous these tropical diseases could be, and how much risk I would be exposing myself to if I decided not to get vaccinated.

I researched the options for months on end and compiled the information I discovered into one comprehensive guide, which you’re currently reading.

In this article, I’m going to be covering which vaccinations you should be looking at getting and which ones you’re able to skip. I’ll cover the type of prices you can expect to pay and whether you’ll be able to obtain some of them for free. I’ll also share the possible side effects you may encounter from getting your travel shots, and whether you can get a bunch of them together. I’ll also let you know how soon before your departure date you need to start getting them.

In short, I’m aiming to answer every possible question you could have about vaccines and long-term travel.

An Introduction to Travel Vaccines

If, like me, you grew up in a Western country away from the equator, you likely haven’t had to worry too much about contracting a dangerous tropical disease. If, however, like me, you have the urge to travel far and wide, you likely know you’re going to want to get some vaccines to boost your immune system.

There are hundreds of deadly diseases around the world — many of them clustered around the tropics — so if that’s an area you want to visit, you’re going to want to protect yourself from falling ill.

Fortunately, there are plenty of vaccines to give you immunity against these diseases. I highly recommend getting them if you’re going to be travelling into a high-risk area.

This is an extensive list of the diseases you may encounter and which you can be vaccinated against.

The Dipheria/Tetanus/Polio vaccine: 

Tetanus is a toxin that is distributed via spores, and the disease can be contracted by said spores entering a wound that you may have if you are injured. In short, if you cut yourself or are bitten by a wild animal, you’ll want to get a tetanus shot to prevent you from contracting it.

Tetanus has an incubation period of 3-21 days, and during this time, your muscles start to become rigid, until eventually you’re paralysed and won’t even be able to open your mouth. Tetanus can be fatal, so this is definitely a vaccine you’ll want to opt for, if you haven’t already been vaccinated at home.

Fortunately, polio is rare these days, thanks to the polio vaccine. This disease is primarily contracted through contaminated food and water. It has an incubation period of 7-14 days and in 90% of cases, there will be no symptoms. 8% of cases will experience mild flu-like symptoms, and the remaining 2% will experience paralysis, bladder dysfunction, impaired swallowing, breathing, and speech, which could be fatal. You only need to browse through Google Images for photos of people who have been impacted by polio to know it’s something you definitely want to be protected against.

And finally, diphtheria is a highly-contagious respiratory illness contracted from inhaling water vapour when infected people cough, sneeze, or breathe around you. It has an incubation period of 2.5 days and can kill you.

You can get a combination vaccine that will give you protection against all three of these illnesses at once, and you’ll need to get five booster vaccines in the future. You’ll likely have received the series of jabs and boosters as a kid in school — I did — but it’s worth checking your medical records to make sure. You’ll also want to get a booster every 10 years in order to ensure you’re fully vaccinated, so it’s wise to talk to your doctor or somebody at a travel clinic to see if you’ll need to do this.

Swing on a beach in Thailand

When travelling to Southeast Asia, I opted for the typhoid, hepatitis A + B vaccine. I decided to skip taking anti-malarials for reasons I’ll get into further into this article.

The Hepatitis A and B vaccine: 

Hepatitis A is a liver infection that’s spread via contaminated food and water or from person-to-person contact. Travellers that are coming from sanitary countries with high levels of hygiene are more at risk, as they won’t have developed immunisation from pre-exposure. It’s really tough to avoid hepatitis A, as there isn’t a way to determine if the food/water you’re consuming is at risk, so this is usually recommend by travel clinics if you’re heading to any developing countries.

Hepatitis A has an incubation period of 3-6 weeks and over 90% of people infected will not show any symptoms. For the 10% that do show symptoms, they’ll experience a fever, joint and muscle pain, an upset stomach, pain in the upper-right quadrant of the stomach, a rash, nausea/vomiting, dark urine, pale stools, and diarrhoea. These symptoms are then following by jaundice and itching. It can then result in liver failure and potentially death.

Hepatitis B is spread from person to person via infected bodily fluid, such as blood/blood contact, infected medical equipment and sexual transmission, and you’re more likely to be infected when in developing countries. Symptoms are much the same as hepatitis A: fever, joint pain, rash, and jaundice, and in some cases, hepatitis B can lead to permanent liver damage and liver cancer.

The Japanese B Encephalitis vaccine: 

Japanese B Encephalitis is contracted through the bite of a mosquito. These mosquitoes are normally found in rice paddles, as well as on pigs, birds, and the Siberian stork. Japanese B Encephalitis sometimes exhibits no symptoms, although some people experience fever, encephalitis, meningitis and paralysis. Recovery is slow and long-term debility is common. There is a mortality rate of 30% in children.

Despite this sounding like a pretty terrible disease, the good news is that it’s very rare, and that means that most travellers opt to not get the Japanese B Encephalitis vaccine. I’ll cover the situations where you might want to get this vaccine below.

The Rabies vaccine: 

Rabies mostly infects animals, but humans can contract it if they’re bitten by an infected dog, bat, monkey, etc. Once you’ve been bitten, the virus then transfers through the animal’s saliva to you. Symptoms include spams in your diaphragm, convulsions, and cardiac or respiratory arrest.

Guys, rabies is no joke, because if you don’t seek treatment within a couple of days of being bitten, you’ll die. Yep, I was shocked to learn that there are only 10 people who have ever been recorded to have survived rabies within a vaccine or treatment.

You might think this means that the rabies vaccine is an essential, but this shot is an interesting one. What you’ll actually be receiving when you travel is a pre-exposure vaccine.

What this means is that when you’ve been bitten by a rabid animal — say a monkey in Bali — you’ll need to seek immediate medical treatment and receive a series of five injections over the course of a month. If you’ve had the pre-exposure vaccine before you travelled (a series of three shots), you’ll only need to receive two further injections if you get bitten while travelling. That’s five vaccines in total in either situation, and the vaccine just means spreading them out.

And yes, that does mean that whether you’ve had the vaccine or not, you’ll need to seek immediate medical treatment and get injected if you get bitten — the vaccine just means you won’t need as many at that time. Because of this, I’ve always skipped out on the rabies vaccine and figured I’d suck it up and get all five in the case of being bitten.

The Tick-Borne Encephalitis vaccine:

Tick-Borne Encephalitis is transferred to humans via the bite of an infected tick., and it can also be transmitted via milk from infected animals.

Tick-Borne Encephalitis is a flu-like illness, with symptoms appearing within 7-14 days of being bitten. The symptoms can include fever, headache, nausea and photophobia, which could lead to neck stiffness, convulsions and an altered mental state. It could also lead to meningitis, encephalitis and muscular paralysis.

The chances of contracting this are very, very low, unless you’re going to be hanging out in farms, or hiking/camping in Eastern Europe, Russia, and China. I’ve never opted for this vaccine because the risks are super-low, and simply take care not to be bitten by ticks if I’m hiking in any high-risk areas.

The Typhoid vaccine:

Typhoid is transmitted via contaminated food and drink. The symptoms include fever, headache, confusion, abdominal pain and constipation, as well as a rash. You can also die from typhoid fever, so this is something you’ll want to avoid.

You’ll likely need to get the typhoid vaccine if you’re going to be heading into the tropics, as it’s fairly common there and easy to contract through eating/drinking.

The Yellow Fever vaccine: 

The yellow fever vaccine is an interesting one, as it’s the only one on the list that’s mandatory. If you’re going to be travelling in South America or Sub-Saharan Africa, you’ll need to get the yellow fever vaccine. Many of the countries with yellow fever require you to have evidence of your vaccine in order to let you in the country, and once you leave, your home country will require proof that you’re vaccinated to let you back in, too

Yellow fever is a nasty disease that’s spread via mosquitoes, so it’s something you’ll definitely want to be protected against. The main symptoms of yellow fever is fever, muscle aches, nausea, dizziness, a red face, vomiting blood, jaundice, bleeding from your nose, mouth, and eyes, liver and kidney failure, and seizures/coma. You can die from yellow fever.

If you want to travel around the South Pacific (this beach is in Tonga), you’ll want to make sure you have your typhoid and hepatitis A vaccines.

What vaccines do I need for where I am going?

Okay, so that was a whole wall of information, and I wouldn’t be surprised if you’re feeling overwhelmed, confused, and concerned you’re going to need a whole host of vaccines for your upcoming vacation.

For the most part, though, you’ll probably need only three or four. To help you figure out which ones you’ll need, let’s take a deep dive into the countries where you’ll find each of these diseases.

Tetanus is present worldwide. Because of this, it’s definitely worth getting the vaccine, no matter where you’re travelling to. It’s likely, though, that you’ve already been vaccinated for this (a lot of people are), so check your medical records to see.

Polio is very rare these days (there were only 22 cases in 2017), thanks to a solid vaccination program around the world. Today, you’ll only need to worry about polio if you’re going to be travelling to Afghanistan, Nigeria, or Pakistan, and even then, your chances of contracting it is low. Either way, as with tetanus, you’ll probably been vaccinated against this as a kid, so it’s worth checking to see if you have if this is something you’re concerned about.

Diphtheria is found worldwide, and you’ve probably been vaccinated against it as a child. Check if you have, as this may be one less vaccine you’ll need to get.

Hepatitis A is present in pretty much all countries with low levels of sanitation. If you’ll be heading to any countries in the tropics, you’ll want to get this vaccine.

Hepatitis B is found in Southeast Asia, the Middle East, the South Pacific, Africa, and Latin America, including the Caribbean. In other words, you’ll probably want to get this vaccine if you’re heading to any developing countries. You can get this vaccine in combination with hepatitis A, which means one less jab to get!

Japanese B Encephalitis can occur following the rainy season in China, regions of Nepal, northern Burma, eastern and southern states of India, northern Sri Lanka, northern Thailand, Laos and Vietnam. Occasional outbreaks have been reported in Malaysia, Indonesia, Korea, Singapore, southern parts of Thailand, southern Sri Lanka and all of India.

Rabies has a greater risk in Asia, Africa and South America.

Tick Borne Encephalitis is found in Russia, Austria, Hungary, the Balkans, Czech Republic, Slovakia and Scandinavia. It can also be found in eastern parts of China. It’s usually found in areas with high grass, so if you’re not going to be camping or hiking, you probably don’t need to worry about it.

Typhoid is present worldwide, however it is worse where food and water may be contaminated with sewage — in Africa, much of Asia, and South America.

Yellow Fever is present in tropical Africa and South America. You will probably be required to show a Yellow Fever vaccination certificate to enter certain countries if you are traveling from an infected area.

I was worried about getting my yellow fever vaccine to enter Mozambique, but fortunately, I experience no side effects and spent most of my time in the wonderful beach town of Tofo! 10/10; worth getting vaccinated for.

When should you get your vaccinations?

By now, you probably have a good idea of which vaccines you’re going to need, so now it’s time to start planning a vaccination schedule. Some of the jabs require you to receive several doses, so you’ll want to make sure you have enough time before your departure date to fit them all in.

Let’s take a look at how long you can wait before leaving to get your vaccines.

Hepatitis A and B – The vaccine requires two doses, 30 days apart, which will provide you with one year of protection. You can then have a booster vaccination 6 to 12 months later which will give you 20 or more years of protection. It is best to have the first shot 6 months before your departure date so you can complete the full course before leaving. If this is not possible then you can have the first two shots before you leave, and have the booster shot whilst you are on the road.

Japanese B Encephalitis – three doses on days 0, 7-14 and 28. You will be immune one month after your final dose.

Rabies – days 0, 7, 21-28. You can then have a booster every 2-3 years.

Tick-Borne Encephalitis – Take two does. One at 0 days and the other 4-12 weeks before that.

Typhoid – One dose will protect you for three years, so you can get it earlier than the others.

Yellow Fever – Must be given 10 days before leaving. As this is a live vaccine it has to be given on the same day as other live vaccines (Polio), or 3 weeks apart.

I have been told that if you have left it very late before sorting out your vaccinations, it is is possible ALL of them can be administered at once, but that sounds awful, so get planning early on!

How expensive are the vaccines?

The most important thing is to shop around. Don’t settle for the first quote you are given, look at lots of different companies and try to find the best prices. I started with my doctor’s surgery and found them to be extremely expensive, and after looking around for a bit, I managed to find the same vaccinations for half the price! Prices obviously will vary from place to place, and this is only speaking for the UK. The following will give you some rough averages of prices I’ve found from my research.

It is possible for you to be able to obtain some vaccinations for free from the NHS in the UK, and the three main ones that are normally covered are:

Dipheria/Tetanus/Polio
Hepatitis A
Typhoid

Depending on which borough you live in, you may be able to get even more for free – I have a friend that even managed to get the rabies vaccination for free. Call your doctor’s surgery and find out what’s on offer.

I looked around and this is a list of the cheapest and most expensive prices I found for each of the vaccines:

Diphtheria/Tetanus/Polio:
Cheapest Price: £25.00
Most Expensive Price: £50.00

Hepatitis A:
Cheapest Price: £45.00
Most Expensive Price: £85.00

Hepatitis B:
Cheapest Price: £30.00
Most Expensive Price: £95.00

Japanese B Encephalitis:
Cheapest Price: £50.00
Most Expensive Price: £100.00

Rabies:
Cheapest Price: £17.50
Most Expensive Price: £40.00

Tick Borne Encephalitis:
Cheapest Price: £70.00
Most Expensive Price: £110.00

Typhoid:
Cheapest Price: £25.00
Most Expensive Price: £40.00

Yellow Fever:
Cheapest Price: £45.00
Most Expensive Price: £80.00

How long do the vaccinations last?

Dipheria/Tetanus/Polio: 10 years
Hepatitis A: – Long term
Hepatitis B: – 10 years
Japanese B Encephalitis: 1 year
Rabies: 1-2 years
Tick Borne Encephalitis: 1-3 years
Typhoid: 3 years
Yellow Fever: 10 years.

Any side effects to the vaccines?

All vaccines are likely to cause redness, pain or swelling around the injection site. However, it is possible to experience other side effects, which are listed below, and are quite rare:

Dipheria/Tetanus/Polio – Mild headaches, aching of muscles and a mild fever. Severe reactions are rare.

Hepatitis A – Fever and a headache. Less common side effects are bruising, stiffness in the neck, sore throat, tiredness, nausea, stomach cramps and agitation.

Hepatitis B – Fatigue, headache, irritability, sore throat, tiredness, weakness.

Japanese B Encephalitis – Little adverse effects.

Rabies – Swollen glands, headache, nausea, diarrhea, muscle aches, chills.

Tick-Borne Encephalitis – Apparently it is manufactured using chicken eggs so if you have an allergy to chicken or eggs you should avoid this vaccine. Side effects include joint pain, nausea, tiredness, fever, vertigo, vomiting, hypersensitivity.

Typhoid – Headache, muscle or joint pain, nausea, vomiting, fatigue, abdominal pain and mild fever. Some individuals can develop diarrhea, and allergic reactions like, skin rash, hives, itching and swelling of the eyes or face after taking the oral typhoid vaccine.

Yellow Fever – Tiredness, muscle aches. There are more serious side effects associated with the vaccine so you will have to wait at the clinic for 30 minutes after having had the vaccine to check that you are ok, and not about to have a serious allergic reaction – anaphylaxis. Also rare is encephalitis and inflammation of the liver or kidney. Complications are more likely in the over 70s.

Malaria/Dengue Fever

I saved the most important diseases until last. Malaria/dengue/Zika, etc are serious and sometimes fatal diseases that are spread via mosquitos. When you are bitten by an infected mosquito, a parasite enters the bloodstream and travels to the liver, where they multiply before returning back into the bloodstream to attack the red blood cells. These parasites continue to multiply inside the red blood cells until they burst, releasing even more parasites into the plasma.

Malaria is present in over 100 countries and 40% of the World’s population is at risk. Large areas of Central and Southern America, Africa, the Middle East, India, Southeast Asia and Oceania are considered malaria risk areas.

Common symptoms of malaria consist of flu-like symptoms – the chills, headache, muscle aches and fatigue. Symptoms can also include nausea, vomiting, diarrhoea, loss of red blood cells, as well as jaundice and anemia.

The symptoms normally occur between 10 days and 4 weeks after exposure being bitten by the infected mosquito, with it sometimes being as late as a year.

Any traveler that becomes ill with a fever or flu-like illness whilst traveling, and up to a year after returning from the trip should immediately seek medical attention.

There is not a vaccine available for malaria, but you can take anti-malaria tablets to prevent contraction. As well as taking the tablets you should be vigilant and try to avoid getting bitten as much as possible. You can do this by wearing insect repellent, especially at dawn and dusk when the mosquitoes are most prevalent. Wearing clothes that cover a lot of your skin will also help to prevent bites.

Anti-malarial tablets

Due to growing immunity from mosquitos, different tablets work best in different areas of the world. These are the five main anti-malarial tablets you’ll be likely to be prescribed.

Chloroquine – Start one week before travel and continue for 4 weeks after you return. Can be taken for periods exceeding 5 years. Can cause nausea and mouth ulcers.

Paludrine – Start one week before travel and continue for 4 weeks after you return. Can be taken for periods exceeding 5 years.

Mefloquine – Start 2.5 weeks before travel and continue for 4 weeks after you return. Can be taken for up to one year.

Doxycycline — Doxycycline is recommended to be used in Southeast Asia and in chloroquine-resistant areas. You should start taking the tablets (100mg a day) 2 days before you arrive and continue taking them for 4 weeks after you leave the area. Doxycycline can be taken up to 6 months and usually have very few side-effects. It can make you very prone to sunburn and it’s recommended you don’t sunbathe whilst taking these.

Malarone – Start 2 days before travel and continue for one week after your return. Can be taken for up to one year.

Are the vaccines really necessary?

Obviously it’s up to you if you want to take that risk but, in my opinion, they are. It’s always better to be safe than sorry. Do you really want some crazy tropical disease ruining the trip you’ve been planning for months/years?

Yes, it’s true, you could not have any vaccinations, and be absolutely fine, but that’s definitely not a risk I’m willing to take, and for the sake of a few hundred pounds, I’d rather be safe…

Sandfly bites on back

Fortunately, these aren’t mosquito bites… I was attacked by sand flies in Cambodia!

As for me…

I visited 1st Contact Travel Clinic in London for my first consultation about vaccinations. If you live in London, I would definitely recommend this company. They’re extremely helpful and have the lowest prices I’ve managed to find online. They also don’t charge for consultations or to get vaccination certificates.

My doctor offers hepatitis A and typhoid vaccinations for free on the NHS, so I will be getting those from there. I will be getting my hepatitis B vaccine from 1st Contact Travel Clinic in London. I’m also bringing 6 months worth of doxycycline as a malaria preventative.

An Update: Eight Years Later

As of 2018, I’ve been travelling continuously for eight years and a lot has changed. It’s time for an update!

As I wrote above, when I left for my round-the-world trip, I got my Hepatitis A, Hepatitis B and Typhoid vaccines. My Hepatitis A and B needed a top-up after a year and fortunately I happened to be back in London at that time. I travelled to 1st Contact Travel Clinic once more to get my vaccines.

I first visited Sub-Saharan Africa in 2017, and I got my yellow fever vaccine in order to do so. Despite the horror stories I’d read online, I experienced no side effects.

Despite insisting that I’d take malaria tablets while travelling, I rarely have. Instead, I decided to only take anti-malarials in parts of the world where there’s a huge risk — in my case, that meant Africa. I always take malarone over doxycycline when in Africa because it has fewer side effects and isn’t an antibiotic.

After weighing up the pros and cons while talking to other travellers, I decided there wasn’t enough of a risk in places like Southeast Asia, Latin America, and the Caribbean to warrant taking the tablets. Instead, I smother myself in insect-repellent, cover up at night and use mosquito nets to stay safe.

Travel Insurance

While we’re talking about tropical diseases and staying healthy on the road, I have to mention travel insurance, because whatever you decide for vaccinations, you 100% should travel with insurance. I firmly believe that it’s a true travel essential, alongside your passport and money.

I’ve used World Nomads for my travel insurance provider for eight years and counting and can recommend them if you’ll be setting off to explore the world. I’ve been incredibly happy with them and wouldn’t consider going with anyone else — they’ve always been great to deal with.
