Book this week to give your vaccines time to work.
Some courses can be speeded up. A yellow fever certificate becomes valid 10 days after your vaccine.
These are suggestions only and may differ from what our expert clinician advises at your consultation.
Entry rules
Malaria
Low risk. Tablets are not usually advised.
Schistosomiasis
Present in fresh water, including the Mekong. Avoid swimming or wading.
Zika
There is a risk. Pregnant travellers and couples planning a pregnancy should seek advice before booking.
Sexual health

More than one country?
Add each country when you book and we’ll plan for the whole route.
For most travellers, Hepatitis A, Diphtheria, Tetanus and Polio and Typhoid are advised. Others may be advised depending on your route, how long you stay and what you will be doing. Your pharmacist will only recommend what suits your trip.
Low risk. Tablets are not usually advised. Low risk in most of Cambodia: awareness and bite avoidance. Very low risk at the Angkor Wat temples and around Lake Tonle Sap, including Siem Reap. No risk in Phnom Penh. Mefloquine resistance is widespread in the western provinces bordering Thailand. For travellers at higher risk, atovaquone with proguanil or doxycycline is preferred.
A yellow fever certificate is required for travellers over 1 year of age arriving from countries with a risk of yellow fever transmission, including those who have spent more than 12 hours in transit through an airport in such a country. Not required if you fly direct from the UK.
Ideally six to eight weeks before you fly, so any courses can be finished. If you leave sooner, still book: many vaccines help close to departure.
