Immunizations
No immunizations are required by law to enter Tanzania if you are travelling directly from Europe or the US. If you are travelling from a country where Yellow Fever is present you will need to prove you have had the inoculation.
Several vaccinations are highly recommended when traveling to Tanzania, they include:
- Yellow Fever
- Typhoid
- Hepatitis A
- Diptheria
It is also recommended that you are up to date with your polio and tetanus vaccinations. Rabies is also prevalent and if you're planning to spend a lot of time in Tanzania, it may be worth getting the rabies shots before you go.
Contact a travel clinic at least 3 months before you plan to travel.
Malaria
There's a risk of catching malaria pretty much everywhere you travel in Tanzania. While it's true that areas of high altitude like the Ngorongoro Conservation Area are relatively malaria-free, you will usually be passing through areas where malaria is prevalent in order to get there.
Tanzania is home to the chloroquine-resistant strain of malaria as well as several others. Make sure your doctor or travel clinic knows you are traveling to Tanzania (don't just say Africa) so s/he can prescribe the right anti-malarial medication.
