Vaccinations for Nepal
Nepal is a destination for trekkers, mountaineers, and cultural travellers — Kathmandu, Pokhara, the Everest and Annapurna regions attract thousands of Canadians annually. Health preparation is extensive: altitude sickness is the dominant concern above 2,500 m, but multiple vaccines are needed at all altitudes.

Recommended vaccines for Nepal
- Hepatitis A (all travellers)
- Typhoid (all travellers — high burden)
- Dukoral (not routine; consider for short-term travellers at high risk from traveller’s diarrhea)
- Rabies pre-exposure (strongly recommended — stray dogs common, medical care remote)
- Hepatitis B (if unvaccinated)
- Japanese Encephalitis (Terai lowlands during monsoon — for trekkers spending time in rural areas)
Do you need malaria pills for Nepal?
Usually not. Malaria risk in Nepal is low and confined to specific areas, so most travellers do not need tablets — but it depends on exactly where you are going.
Malaria risk in Nepal is confined to the Terai lowland border areas near India. Kathmandu, Pokhara, Everest Base Camp, Annapurna Circuit, and Langtang regions are malaria-free. Very limited prophylaxis need for standard trekking itineraries — our physician reviews your specific route.
Key health considerations
- 1Altitude sickness (AMS) is the primary health risk above 2,500 m — acetazolamide (Diamox) prescription available from our physician.
- 2Severe Acute Mountain Sickness, HACE (High Altitude Cerebral Edema), and HAPE (High Altitude Pulmonary Edema) can be life-threatening — know the symptoms and acclimatize properly.
- 3Rabies from stray dog bites is a significant risk — pre-vaccination is critical because rabies immunoglobulin is scarce in remote trekking areas of Nepal.
Travel-health tips
- Acclimatize properly — never ascend more than 300–500 m per day above 3,000 m. "Climb high, sleep low."
- Carry physician-prescribed Diamox and a wilderness first aid kit including acetazolamide for altitude emergencies.
- Rabies pre-exposure vaccination is critical for Nepal — immunoglobulin is frequently unavailable in remote trekking areas.

Frequently asked: Nepal
Do I need altitude sickness medication for Nepal?
For treks such as Everest Base Camp, the Annapurna Circuit, Langtang or Manaslu, a slow ascent comes first: above 3,000 m, Canadian guidance says to sleep no more than 300 m higher each night, with a rest day every 2 or 3 days. Acetazolamide (the generic of Diamox) is considered for a big one-day gain in sleeping height, a rapid ascent above 3,000 m, or a past episode of altitude sickness; it is started 24 hours before ascent. Our physician decides whether you need it at your pre-travel consultation.
Why is rabies vaccine especially important for Nepal trekking?
Stray dogs are ubiquitous in Nepal — in towns, on trekking trails, at teahouses. A bite or scratch requires immediate post-exposure treatment. Without pre-vaccination, you need rabies immunoglobulin (RIG) — which is frequently unavailable or exhausted in remote Nepal trekking areas. Pre-vaccination completed less than 3 years before a bite (or followed by a booster) eliminates the need for RIG, turning a potential life-threatening situation into a manageable 2-dose booster course.
What travel vaccines do I need for Nepal?
For Nepal, we recommend: Hepatitis A (all travellers), Typhoid, Rabies PrEP (trekkers — animal contact risk in rural areas), and Japanese Encephalitis for low-altitude stays during monsoon. Altitude sickness is not a vaccine-preventable condition but Diamox (acetazolamide) can be prescribed during your consultation. Malaria is a risk in the Terai lowlands during monsoon.
Do I need a Rabies vaccine before trekking in Nepal?
Yes, pre-exposure rabies prophylaxis is strongly recommended for Nepal trekkers. Nepal has a high dog and monkey population, and post-exposure treatment in remote trekking areas can be unavailable or delayed. If your 2-dose pre-exposure series was completed less than 3 years before a bite (or you have had a booster), you need only 2 post-exposure doses (not 4) and no rabies immunoglobulin — which is often unavailable in Nepal.
