Vaccinations may be required for this trip. Please consult your doctor or a travel health specialist. The choice of vaccinations can depend on a range of issues including the specific destination, the duration of the trip, your personal health and of course what vaccines you have had before.
Compulsory vaccines: These days the only compulsory vaccine is for yellow fever, which is required for many countries in Africa and South America. It should be done at least 10 days before travel and must be recorded in an official certificate book. Please note that very often you may not need to show this certificate book when entering these countries, but you will need to produce it to immigration/customs on returning to your home country.
Routine Background Vaccines: We strongly endorse current public health recommendations that all travellers should be up-to-date with their routine vaccines such as tetanus, diphtheria, measles/mumps/rubella, polio and influenza, and paediatric vaccinations for children.
Travel Vaccinations: While the food and water-borne diseases such as hepatitis A and typhoid will apply to most of our travellers, other travel vaccines such as hepatitis B, rabies, meningitis, Japanese encephalitis and cholera may apply to select travellers, especially long-term travel. Travel health experts can advise on what is required and also what is not required!
Malaria: There is no vaccination against malaria, which is transmitted by mosquito bites and is a risk in many less-developed tropical areas, particularly in Central, East and West Africa, Melanesia (especially Papua New Guinea) and the Amazon region. In Asia (particularly India) and Central America it may be a problem in rural areas. Protection against mosquito bites is essential and where the risk is considered high, anti-malarial medications are recommended. Anti-malarial medications should be discussed with experts as there are different medications available and not all medications suit all people or all destinations. We prefer that trekkers to altitude try to avoid the use of mefloquine (Lariam) if possible.
For travellers from Australia and New Zealand, we strongly recommend Travel Doctor-TMVC clinics to obtain the most up-to-date advice on health risks and vaccinations (see www.traveldoctor.com.au for locations and detailed vaccine information or phone 1300 658 844 for an appointment in Australia). Some vaccines require more than one dose, so arrange for your visit at least 4-6 weeks before you travel. Travellers living outside Australia and New Zealand will need to consult a similar organisation in their own country (please ask your travel agent for recommendations), but can still access the following link for information:

Acclimatisation to high altitudes (generally for trips over 3500 metres)
We take this very seriously, which is why we have one of the best safety records in the Himalaya. We have 30 years' experience in the region and our success rates on high altitude treks are very high. Our itineraries allow for a safe approach to high altitudes, following the guidelines set out by the Himalayan Rescue Association. We even carry Portable Altitude Chambers (PAC bags) for your safety and peace of mind on all treks proceeding above 4000 metres.
Our leaders are highly experienced mountain guides. Please follow their instructions very carefully as you ascend to high altitudes: walking slowly rather than hurrying, wearing sunglasses during the day, maintaining a high level of (non-alcoholic!) fluid consumption, not sleeping during the day, wearing adequate warm clothing are all factors of importance. Your leader will brief you fully on these considerations prior to the start of your trek.
In addition, if you are taking any medications with you which may have been suggested as an aid to acclimatisation - Diamox is quite commonly suggested - it is vital that you advise your leader in Kathmandu before you leave for the start of the trek. He will then discuss with you the advantages and disadvantages of taking this medication, and in particular when you should consider starting it and the duration for which it should be taken. Be aware that many trekkers have no need for such medication.
