Editor’s Note: This is general travel health advice and is not intended to replace individual advice from your GP, specialist nurse or another qualified travel health professional, that has been tailored to your past medical history, medication or travel plans. This article was reviewed and updated on November 2026. It is routinely reviewed every 3 years unless new clinical evidence emerges.

Planning your gap year should be exciting. Choosing where to go, working out your route and imagining everything you’ll do are all part of the adventure. Sorting out vaccinations, prescriptions and medical insurance may be less entertaining, but giving them a little attention now can save you a lot of unnecessary hassle later.

As a former nurse with a background in emergency care and travel and tropical medicine, I know how much good preparation can help. That means understanding which precautions are relevant to your trip, allowing time to arrange them and making sure you have the medication, supplies and information you need to look after yourself while you’re away.

This pre-travel health checklist takes you through what to organise and when, starting six months before departure and finishing with the final checks before you leave. Whether you’re heading off for a few weeks or taking a year to explore the world, getting these practicalities sorted early leaves you more time to enjoy the part you actually booked the ticket for.

6 Months Before You Go

Six months before your trip is a good time to start researching health precautions and arranging anything that needs a longer lead time. You don’t need to sort everything out at once, but getting started early gives you time to prepare without rushing.

Research Your Destinations And Travel Plans

Once you have an idea of where you want to go, start looking at the health advice for those destinations. You don’t need every overnight stop booked or your entire route mapped out, but knowing the countries and regions you expect to visit and the types of activities you want to do gives you a useful starting point for your preparation.

Small details can matter a lot. Spending a week exploring a city can involve different health considerations from spending a month trekking through remote countryside in the same country. Think about when you’ll be travelling, how long you’ll stay, your accommodation and any activities you’re planning. Include countries you’ll be passing through too, as these can affect entry requirements and the advice you receive.

Use genuine reputable sources like the NHS to research recommended vaccinations, malaria risk, current outbreaks and other relevant health precautions. Don’t just ask AI and take that as medical advice! Make a note of anything you need to discuss at your travel health appointment, including possible changes to your route. You aren’t expected to interpret every recommendation or decide which medication you need yourself; this research is just a start that helps you ask informed questions and gives the professional advising you a clearer picture of your trip.

Keep it in perspective, too. Finding a disease listed on a country page does not mean you are likely to catch it. The purpose is to identify which risks apply to your circumstances and what you can do about reducing them as much as humanly possible, rather than work your way through a catalogue of tropical diseases until you’re afraid to leave the house.

Discuss Existing Health Conditions And Ongoing Care

Having a medical condition does not automatically stop you taking a gap year or travelling independently, but it is worth discussing your plans with your GP or nurse early. This includes mental health conditions as well as physical ones. Six months gives you useful time to arrange reviews, complete any necessary treatment and work out how to continue your care while you’re away.

Explain where you hope to go, how long you’ll be travelling and what you want to do. A clinician who knows your health can help you understand how the climate, activities, long journeys or access to treatment might affect you. If you need regular blood tests, specialist appointments or ongoing treatment, agree how these will be managed during the trip rather than assuming you can simply pick them up wherever you happen to be.

It is also worth discussing what to do if your condition worsens. Ask which changes you can manage using your existing treatment plan, which symptoms need medical attention and whether any activities or circumstances require additional precautions. Having that plan gives you something practical to follow if you feel unwell, especially somewhere unfamiliar.

If you use mobility aids, medical equipment or need support with transport or accommodation, start investigating those arrangements now too. The aim is to make the trip work for your needs, with enough time to organise the support that lets you enjoy it.

Arrange Travel Insurance When You Book Your Flight

Arrange suitable travel insurance when you book your trip, rather than leaving it until the week before departure. I know no one likes paying for insurance, but if it helps just consider it part of the cost of your flight. That’s what I do. Depending on the policy, cancellation cover can protect money you have already paid if an insured event prevents you from travelling. Check when that cover begins, particularly if you are buying an annual policy with a future start date.

For a gap year or longer backpacking trip, check that the policy covers the full time you’ll be away, every destination and the activities you expect to do. An annual policy may limit the length of each individual trip, so twelve months of insurance does not necessarily mean cover for twelve continuous months abroad. Trekking, diving, volunteering and working overseas may also have conditions or require additional cover.

Pay particular attention to medical treatment, emergency evacuation and repatriation, including any limits, exclusions and excesses. If you’ll be trekking somewhere remote, for example, check whether search and rescue is included and whether altitude limits apply. A policy that covers a hospital bill is only part of the picture if getting you to that hospital requires a helicopter.

Answer medical screening questions fully and accurately, including those about existing conditions, medication, investigations or pending treatment. If anything is unclear, ask the insurer and keep written confirmation of its answer. Check what changes you must report before departure or during the trip, too. The cheapest policy is only a bargain if it provides the cover you actually need.

3 Months Before You Go

With your travel plans taking shape, now is a good time to arrange your travel health appointment and start organising vaccinations, medication and any supporting documents. Giving yourself this breathing room makes it easier to fit appointments around everyday life and deal with anything that needs more time.

Make An Appointment With A Travel Health Professional

This is the perfect time to book a travel health appointment, and you have a lot of options open to you, from your GP practice to a specialist travel clinic or a pharmacy offering travel health services. Check what the service provides when booking, as availability, charges and the vaccinations offered can vary.

Current NHS advice is to seek travel health advice at least four to six weeks before departure. Arranging your appointment at this three-month stage gives you more time for any courses of vaccinations, additional assessments or practical arrangements your trip requires. There is no benefit in waiting until the minimum recommended window if you already know your plans.

Bring your proposed itinerary, including countries you’ll pass through, dates, likely accommodation and any activities you’re considering. Take your vaccination records if you have them, along with details of your medical conditions, allergies and all medication you use, including anything bought over the counter. If your route is flexible, say so. You don’t need a rigid itinerary, but your adviser needs to understand the range of places and activities you have in mind.

A proper travel health assessment should look beyond which injections you need. It is an opportunity to discuss malaria prevention, food and water precautions, bite avoidance and any risks specific to your health or planned activities. Ask questions and make sure you understand the recommendations, including what you need to arrange next and when.

Check Your Routine Vaccinations And Arrange Travel Vaccinations

Start by checking your routine vaccinations are up to date, including protection against measles, rather than concentrating only on diseases you associate with tropical travel. Take any records you have to your appointment. If you aren’t sure what you’ve previously received, ask your GP practice to check; you don’t need to guess or assume that childhood vaccinations covered everything.

The travel vaccinations recommended for you will depend on your destinations, route, activities, length of stay and medical history. There is no standard collection of injections that every backpacker needs. Your travel health professional should explain which vaccinations are recommended for your protection, whether any certificates are required for entry and when each dose needs to be given.

Current NHS advice is to arrange travel vaccinations at least four to six weeks before departure, because some require a course of doses and protection takes time to develop. Starting the process at this three-month stage gives you room to complete the appropriate schedule. Some vaccines can be given at the same appointment, while others need particular spacing; let the clinician organise this rather than trying to work it out yourself.

Tell the person advising you about previous vaccine reactions, any condition affecting your immune system and the medication you take, as these can affect which vaccines are suitable. If a particular vaccine cannot be given, discuss what that means for your plans and what other precautions are available. It does not automatically mean cancelling your adventure, but it does need an individual assessment.

Before leaving the appointment, make sure you know which doses are still outstanding, book any follow-up appointments and keep a record of what you have received. Some travel vaccinations are available free through the NHS and others are paid for privately, so check the costs when arranging them.

Arrange Your Malaria Prevention

Discuss your proposed route with a travel health professional to establish whether you need antimalarials. Recommendations depend on the specific areas you’ll visit, the time of year, duration of exposure and your medical history. Malaria risk does not follow national borders neatly, so take as much detail about your itinerary as you can, including rural stays, overnight excursions and any plans that are still flexible.

If medication is recommended, your doctor or nurse should assess which option is suitable for you, taking account of existing conditions, other medicines and any previous side effects. Raise any concerns during this discussion. Choosing an appropriate medicine and understanding how to take it is far more useful than either dismissing side effects or letting someone else’s horror story put you off prevention altogether.

Arrange your prescription and supply in advance, allowing enough tablets for the whole course, including the required period after leaving the malaria-risk area. For a long trip, discuss supply arrangements early rather than assuming you can buy the same medicine wherever you happen to be. Check its storage requirements too, particularly if you’ll be carrying it through hot climates for several months.

Before the appointment ends, make sure you understand when to start, how often to take it and when to stop. These instructions depend on the medicine prescribed and the date you enter the malaria-risk area, which may be weeks into your travels. Ask what to do about missed doses, vomiting or side effects, and keep the instructions with your medication. Add the start and finish dates to your itinerary so you have a clear plan to follow.

Plan mosquito bite prevention at the same time. Tablets are only one part of malaria prevention, and they do not protect against other mosquito-borne infections such as dengue. Include suitable repellent and clothing in your preparations, and check whether your accommodation provides effective mosquito protection or whether you need to carry a treated net.

Plan Any Regular Medication And Medical Supplies

If you take regular medication, speak to your GP or prescribing team about how you’ll manage it throughout your trip. Explain how long you expect to be away and whether you need blood tests, reviews or other monitoring. For a longer gap year, you may need to agree arrangements for continuing treatment abroad; don’t assume your usual repeat prescription will cover an indefinite period away.

Work out how much medication and equipment you need, allowing for possible delays, and arrange supplies early. Include anything you use intermittently, such as inhalers or medication for flare-ups, as well as everyday prescriptions. If you need further supplies while travelling, agree a realistic way to obtain them through a reputable healthcare provider. Medicines sold under familiar names abroad may have different ingredients or strengths, so carry a record of the generic names, doses and formulations you use.

Check the rules for carrying your medication into every country on your route, including transit stops. A medicine being prescribed or freely available in the UK does not mean it is permitted elsewhere. Some countries require advance permission, supporting letters or limits on the quantity you can bring. Check with the relevant embassy or official authority while you have time to arrange the paperwork.

Ask your prescriber for appropriate documentation explaining your medication and any equipment you need, and obtain copies of your prescriptions. Keep medicines in their original, labelled pharmacy packaging so they can be identified clearly. If you use injections, oxygen or other medical equipment, contact the airline beforehand to establish what documentation and arrangements it requires.

Storage needs planning too. Ask your pharmacist how to protect your medication from heat, freezing or moisture during journeys and at your accommodation. If it needs refrigeration, establish how you’ll maintain the required temperature throughout the trip. Sorting this out now is considerably easier than arriving somewhere hot with a month’s supply of medicine and discovering that your room has neither a fridge nor reliable electricity.

Consider A Dental Check-Up And Complete Any Necessary Treatment

If you’re due a dental check-up, have an unresolved problem or are midway through treatment, arrange an appointment well before departure. This is particularly useful before a long trip or extended time somewhere remote. You don’t need an extra examination simply because you’re travelling, but toothache you’ve been putting up with at home deserves attention before you find yourself looking for a dentist halfway through a jungle trek.

Tell your dentist how long you’ll be away and discuss any treatment they recommend, allowing time for follow-up appointments and recovery where needed. If treatment cannot be completed before departure, agree a plan for continuing it and ask for any records you may need to take with you.

Check your travel insurance’s emergency dental cover too, including its limits and exclusions. Don’t assume it will pay for routine care or treatment you already knew you needed. Pack your usual dental hygiene supplies, along with anything you need for braces, retainers or dentures, so you can maintain your normal care while you’re away.

Arrange A GHIC Or EHIC

If your route includes countries covered by the UK Global Health Insurance Card scheme, check your eligibility and apply through the official NHS service. A GHIC is free, so avoid websites charging to arrange one for you. If you already have a valid UK European Health Insurance Card, you can generally continue using it until it expires; some people remain eligible for a new UK EHIC instead.

These cards provide access to medically necessary state healthcare in participating countries on the same basis as someone who lives there. That does not necessarily mean treatment is free. You may have to pay the same charges as local residents, and the card does not cover private healthcare or the cost of bringing you home for medical treatment.

Check which countries your particular card covers rather than assuming “Global” means everywhere. If you need ongoing care for an existing condition, investigate arrangements before departure; treatment such as dialysis may need to be booked with a suitable provider in advance.

Apply early enough for the card to arrive, check its expiry date against your travel plans and keep it with your important documents. It is useful additional protection alongside suitable travel insurance, and you need to arrange both.

1 Month Before You Go

With departure getting closer, check that the arrangements you’ve made are coming together and sort out the practical details. This is the time to confirm outstanding appointments, prepare your health supplies and make sure you know how to get help if you need it.

Check Your Vaccination And Medication Schedules

Review the plan agreed at your travel health appointment and check that any remaining vaccination doses are booked. If you have missed an appointment or your departure date has changed, contact the clinic so they can advise you on the appropriate schedule. Don’t assume a missed dose means starting again, or try to rearrange the intervals yourself.

Check that prescriptions have been issued and that you can obtain the medication and supplies you’ve arranged. If anything is unavailable, contact your pharmacist or prescribing team while there is time to discuss an alternative. For medication that requires monitoring, confirm that any necessary reviews or tests are organised.

Write down the dates for starting antimalarials and any other treatment with a specific travel schedule. Base these on the instructions you were given and your actual itinerary, particularly if you won’t enter a malaria-risk area until later in the trip. Set reminders if helpful, and keep a copy of the instructions somewhere you can access without an internet connection.

If your route, activities, health or regular medication have changed since your assessment, let your travel health professional know. An extra country, a remote trekking trip or a new prescription may affect the original recommendations, and this is a useful opportunity to check that your preparations still fit your plans.

Prepare Your First Aid Kit And Health Supplies

Put together a manageable first aid kit suited to your trip, with supplies you know how to use. If you don’t know how to use it or you aren’t trained in how to use it, it will just be dead weight, so you can put that tourniquet and rebreather back. Plasters, sterile gauze, non-stick dressings, tape and basic wound-cleaning supplies are a useful starting point. Check that everything is in good condition, within its expiry date and somewhere you can reach without emptying your entire backpack onto the pavement.

Think beyond patching up injuries, too. Sunscreen, suitable insect repellent, oral rehydration sachets and condoms can be just as useful as dressings. Depending on where you’re going, you may also need a treated mosquito net or a reliable way to make drinking water safe. Pack for your actual trip rather than buying an enormous medical kit because the packaging has a mountain on it.

Ask a pharmacist about suitable medicines for minor ailments, especially if you take regular medication or have allergies or an existing condition. Keep the instructions and check whether you can take them into the countries you’re visiting. Your kit should help you deal with straightforward problems, alongside knowing when to get medical help.

If your first aid knowledge is rusty, consider taking a practical course before you go. Knowing how to assess a situation, give basic assistance and recognise when someone needs professional help is considerably more useful than carrying equipment you have never learned to use.

Organise Your Medical Information And Emergency Contacts

Write a short medical summary listing your existing conditions, allergies and medication, including generic names and doses. Add your usual clinician’s contact details and any relevant treatment plans. If you have a serious allergy or condition that could affect emergency treatment, ask your healthcare team whether medical identification would be useful.

Save a copy somewhere you can access without an internet connection and keep a paper copy with your important documents. Information stored only in a locked phone or an email account you cannot open won’t help much when someone needs it urgently. If your medical needs are more complex, ask your clinical team what information you should carry and whether a translation would be helpful.

Save your insurer’s emergency assistance number, policy details and the number of someone you trust at home. Make sure that person knows where to find anything they might need to help you, and agree how you’ll keep in touch if you become unwell. You don’t need to hand over your entire medical history, but a little organisation makes it easier for someone to support you.

Check Your Travel Insurance Cover

Read through your policy again with your current travel plans in front of you. Make sure it covers the whole trip, every destination and any work, volunteering or activities you’ve added since booking. Check any conditions that apply to your plans, such as trekking altitude limits or the qualifications you need for diving.

Check your medical declarations and tell the insurer about any changes you are required to report, including new symptoms, investigations, diagnoses or medication. If you aren’t sure whether something needs declaring, ask and keep a written record of the answer. Sorting this out before you go is much easier than trying to clarify your cover from a hospital waiting room.

Find out how to use the policy if you need treatment. When should you call the assistance service? Does it need to authorise treatment, and might you have to pay first and claim the money back? Keep the emergency number and policy details with your medical information, and make sure you can access money for any excess or upfront payment.

Plan How To Access Medical Help Abroad

This is a bit of a ‘just in case’ plan, but it’s always worth looking up suitable healthcare facilities near your first destinations and anywhere you expect to stay for a while. You don’t need a directory of every hospital along your route, but having an idea of where to go and how to get there saves you starting that research when you already feel awful. Give this more attention if you need specialist care or will be spending time somewhere remote.

Check local emergency numbers and save them somewhere you can find them offline. Find out how your insurer can help you locate suitable treatment, and confirm any arrangements for ongoing care before you go. If you’re joining a trek or expedition, ask what medical support is available and how the operator would arrange an evacuation.

For remote trips, think about how you would contact help. A mobile phone needs coverage, and even once you have reached someone, getting you to treatment may take time. Consider this when choosing routes, guides and activities so you understand what support will actually be available.

Prepare For Long Journeys

Think about looking after yourself on the journey as well as once you arrive. Long flights, coach journeys and train rides can mean hours of sitting still, disrupted meals and awkward medication timings. Keep essential supplies within reach and ask your pharmacist or prescribing team how to manage time-sensitive doses across time zones.

For journeys lasting more than four hours, plan to move regularly. Walk when it is safe, move your ankles and legs while seated, wear comfortable clothing and drink water regularly. Avoid using alcohol or sleeping tablets to get through the journey if they leave you sitting immobile for long periods.

If you have additional risk factors for blood clots, such as a previous clot, recent surgery or significantly reduced mobility, get individual advice before you go. Some travellers may need properly fitted compression stockings or prescribed preventive treatment, depending on their circumstances. Don’t start taking aspirin to prevent travel-related blood clots.

If you need help getting through an airport, boarding transport or travelling with medical equipment, arrange it with the provider in advance. Giving yourself enough time and having the right assistance in place can make the journey much more comfortable, leaving you with more energy to enjoy getting there.

The Week Before You Go

Most of the organising should now be behind you. Use this final week to check that everything is ready, pack your health essentials and deal with any outstanding questions so you can enjoy the excitement of getting away.

Pack Your Medication And Essential Health Supplies

Keep your regular medication and essential medical supplies in your hand luggage, in their original, labelled packaging. Take enough for the journey and possible delays, and keep anything you might need during the flight within easy reach. If you’re carrying a backup supply separately, make sure its storage conditions are suitable too.

Put any arrangements for temperature-sensitive medication into practice, including during transfers and while waiting around. Check that cooling equipment is ready and that you have confirmed suitable storage wherever you’ll be staying. Medicines that need to stay cool may also need protecting from freezing, so follow the advice your pharmacist has given you.

Pack your first aid kit and prevention supplies, checking quantities and expiry dates as you go. Keep useful items such as repellent and sunscreen accessible when you arrive, particularly if you’ll be heading straight into the heat or spending time outdoors before reaching your accommodation.

Check Your Documents Are Packed And Accessible

Check that you have your prescription copies, any supporting medical letters, vaccination certificates and permissions needed to carry medication or equipment. Keep the originals where you can reach them during the journey, rather than buried in checked luggage.

Make sure your medical summary, insurance details and emergency contacts are saved offline, with paper copies where appropriate. Open the files to check they are actually available without a connection. If you have arranged a GHIC or EHIC, check that you have packed the valid card.

Give your trusted contact at home any final information they need, including changes to your itinerary or arrangements for keeping in touch. This should be a quick check of what you have already organised, rather than another afternoon spent assembling paperwork.

Review Destination Health Advice And Outstanding Preparations

Review the latest health advice for your destinations through NHS Fit for Travel or TravelHealthPro, and check the health and entry requirements sections of the UK government’s FCDO travel advice. Look for changes affecting your route, including outbreaks, vaccination certificates and restrictions on carrying medication. If anything affects the preparations you’ve made, contact your travel health professional or the relevant embassy to clarify what you need to do before you go.

Confirm that any outstanding vaccination appointments are in your diary and check the instructions for medication you need to start before entering a risk area. Follow your prescribed schedule rather than starting everything simply because your flight is approaching.

If you’ve become unwell, developed new symptoms or had a change in treatment, ask whether this affects your travel plans and check whether you need to update your insurer.

Left It Until The Last Minute?

If you’re reading this with a flight booked for next week and several things still to organise, don’t panic. Plans come together quickly, appointments can be difficult to get and sometimes life simply gets in the way. Wherever you are with your preparations, it is still worth speaking to a travel health professional.

Contact your GP practice, a pharmacy offering travel health services or a specialist travel clinic as soon as you can, and explain when you’re leaving and where you’re going. If one service cannot see you in time, ask about other options. Take whatever vaccination records you have, along with your itinerary and details of your health and medication, so the appointment can be as useful as possible.

Some vaccinations can still be worthwhile close to your trip, and accelerated schedules are available for certain vaccines. You may not have full protection by the time you leave, so ask what protection you can reasonably expect, whether further doses will be needed and what additional precautions to take.

If your route requires proof of yellow fever vaccination, your International Certificate of Vaccination or Prophylaxis (ICVP) becomes valid ten days after your first yellow fever vaccination and remains valid for life. This is an international rule, so check that it will be valid by the time you reach the country requiring it. If time is tight, discuss this with a registered yellow fever vaccination centre before you travel.

There may still be suitable options for malaria prevention, too. Some antimalarials can be started one or two days before entering a malaria-risk area, although the choice must still take account of your health, other medication and itinerary. Tell your adviser when you’ll actually reach that area, rather than just the date you fly out.

The appointment is also an opportunity to identify the most important preparations still within your control, from arranging medication supplies to understanding food, water and bite precautions. If something cannot be completed in time, your adviser can explain the implications and help you consider any sensible changes to your plans. You haven’t missed your chance to get useful advice simply because you haven’t followed the ideal timeline.

Enjoy Your Travels

Getting these preparations sorted may never be the most exciting part of planning a gap year, but it gives you more freedom to enjoy the adventure. You’ll have the supplies you need, understand the precautions relevant to your trip and know where to turn for help. That is a much better starting point than worrying about every illness you might encounter or hoping you’ll somehow sort everything out when you get there.

Once you’re away, keep up the everyday habits that help you stay well, follow any agreed medication schedules and get further advice if your plans or health needs change. Beyond that, give yourself permission to relax and enjoy what you’ve worked towards. There’s a whole world of food to try, places to explore and people to meet, and looking after your health helps you make the most of it.
