Vaccinations and Health Prep for Nepal Trekking
What the CDC lists for Nepal travellers, from routine and hepatitis A to typhoid, rabies and malaria, plus the health checks, dental visit and medical review to do 6 to 8 weeks before a high-altitude trek.
Start with a travel clinic appointment 6 to 8 weeks before you fly, and bring your route. For Nepal the CDC lists up-to-date routine vaccines, hepatitis A, typhoid for most travellers, hepatitis B for unvaccinated people under 60, rabies depending on your activities, Japanese encephalitis for longer stays or higher-risk activities, and cholera in specific situations. It states that there is no malaria transmission in Kathmandu, Pokhara or on typical Himalayan treks, with prescription prophylaxis advised only for certain low-elevation areas below 2,000 m. A clinic will fit that list to your age, health and plans. This guide sets out the list, a timeline for health prep and the non-vaccine checks that matter more for a high-altitude trek than most people realise.
This is general information, not medical advice. Which vaccines you need depends on you, and only a doctor or travel clinic can decide that. We cite the CDC because its Nepal page is current and specific, and the NHS and CDC Yellow Book for altitude.

What the CDC lists for Nepal
The CDC's traveller page for Nepal says to make sure you are up to date on all routine vaccines before every trip, including measles, mumps and rubella, polio and flu. For other vaccines it says:
| Item | What the CDC says |
|---|---|
| Hepatitis A | Recommended for unvaccinated travellers one year old or older |
| Hepatitis B | Recommended for unvaccinated travellers under 60; those 60 and older may get it |
| Typhoid | Recommended for most travellers; the vaccine is not 100% effective |
| Rabies | Rabid dogs are common; post-exposure vaccine may only be available at larger urban facilities; pre-exposure depends on activities |
| Japanese encephalitis | For people moving to an affected area or staying a month or more; shorter trips with higher-risk activities such as rural camping may also warrant it |
| Malaria | Prescription prophylaxis only in certain low-elevation areas, mainly Sudurpashchim and Karnali provinces below 2,000 m; no transmission in Kathmandu, Pokhara or on typical Himalayan treks |
| Cholera | Active transmission is widespread but rare in travellers; vaccination may be considered |
The list is not a shopping list. A clinic will weigh your trip length, your route and whether you will spend nights in lowland villages. A short trek on the Annapurna Circuit with nights in lodges is a different case from a month of rural travel, and the clinic will say so.
A timeline for health prep
Eight to twelve weeks before: book the travel clinic and a dental check, and start your training plan from our 12-week fitness guide. Six to eight weeks: attend the clinic, start any vaccine courses that need several doses and ask about medicines you might carry, including whether you should discuss Diamox. Four to six weeks: buy your travel insurance with cover for the altitude of your route, using the insurance guide. Two to four weeks: build your first aid kit, break in your boots and check your prescriptions are enough for the trip plus a spare week. One week: copy your documents, brief your emergency contact and read the emergency steps.
Rabies: the one to think about
The CDC's note on rabies is blunt: rabid dogs are common in Nepal, and post-exposure vaccine may only be available at larger urban facilities. On a trek, you will meet dogs in villages and lodges, and most are harmless. The risk is a bite or a scratch miles from a clinic. A pre-exposure course changes what you need to do after an exposure, which can matter if you are days from a city. The decision depends on your time, route and activities, so ask the clinic. Whatever you decide, treat any bite or scratch as an emergency: wash the wound well, tell your guide, and get to a medical facility quickly. Do not feed or pet animals, and keep food out of reach of dogs at lodges.
Altitude is not a vaccine problem
No vaccine or tablet makes you immune to altitude illness. The CDC advises acclimatising for at least 2 to 3 nights at around 2,450 to 2,750 m before going higher, ascending no faster than 500 m of sleeping altitude per night above 3,000 m, and adding an extra night for every 1,000 m gained. The NHS gives the same 500 m figure, adds a rest day at the same altitude every 3 to 4 days and says to see a GP or travel clinic if you have had altitude sickness before or will gain height quickly. That is another reason to see the clinic early: tell them your itinerary, your sleeping altitudes and any previous episodes. Our acclimatisation schedule guide and altitude sickness basics explain the plan, and the Everest Base Camp route page shows a typical one.
Other checks that matter more than they seem
See a dentist: a toothache at 4,000 m is miserable and there is no dentist on the trail. Review any chronic condition with your doctor, especially heart, lung, blood pressure, diabetes, asthma, epilepsy and anaemia, and ask whether altitude changes anything for you. If you take regular medicines, ask about carrying double supplies in separate bags and about how they behave in cold and at height. If you are pregnant or may be, talk to your doctor before choosing a high-altitude route. Check that your eyes and glasses are in order, bring a spare pair, and consider how contact lenses will work in cold and dust. Finally, check your fitness honestly: our matching pace and fitness guide helps you compare yourself with partners, and first-time trekking in Nepal sets realistic expectations.
In Kathmandu and on the trail
Bring your vaccination card or a photo of it, and keep copies of your prescriptions. In Kathmandu and Pokhara there are clinics and pharmacies used to foreign travellers, and the aid posts at Manang and Pheriche (see the clinics guide) help on the two busiest routes. Food and water hygiene is the most common health issue on a trek, and our guides to teahouse food hygiene and water purification cover it. The CDC also warns of leptospirosis from floodwater and contaminated soil, which matters on monsoon-season roads; read monsoon trekking in Nepal if you plan to go then.
Partners and health information
If you travel with partners you have met online, agree what you will tell each other about health. You do not need to share your medical history, but you should share allergies, medicines that someone might need to find in an emergency, and any condition that could affect the group, such as asthma or a heart condition. Contact details on FindTrekkingPartner stay hidden until both trekkers agree, and the same privacy principle applies to health information: share what is needed for safety and nothing more. The partner safety guide lists a simple emergency card, and the altitude and health hub has the rest of the series. For the Kathmandu Valley, where most trips start, allow a day or two in the city before you head for the trail.
Questions to bring to the clinic
A ten-minute appointment goes further with a short list. Take your dates, the route names and the highest point of each, the number of nights above 3,000 m and whether you will stay in lowland villages, camp or sleep in lodges. Say whether you have had altitude sickness before, whether you have any heart, lung or blood conditions and which medicines you take. Ask which of the CDC's items apply to your age and trip length, how many doses each needs and how long before departure, whether a pre-exposure rabies course makes sense for your plan, and what to do after a bite when you are two days from a road. Ask what the clinic suggests for stomach trouble, since many clinics will discuss whether to carry rehydration salts or a prescribed antibiotic, and write the answers down. If you are told something that differs from this guide, follow the clinician: they know you, and we do not.
Records and paperwork
Bring or photograph your vaccination record and keep a copy offline. If you are prescribed anything, ask for a printed note with the generic name of each medicine, and carry it with the medicines in their original packaging. Add the clinic's advice to your emergency card, with your blood group if you know it, your allergies and your insurer's number, and give a copy to your partner. Check that your insurance covers medical treatment for any condition you have declared, and keep the policy wording where you can reach it. None of this is complicated, but all of it is easiest at home, with a printer and a working internet connection, and hardest in a lodge at 3,500 m with one bar of signal.
