Entry requirements
Who Needs One to Enter?
Do you need a yellow fever certificate to enter Tanzania? Who needs it, risk-country layovers of 12 hours or more, timing, Zanzibar and what happens without one.
START HERE
A yellow fever certificate is not required for every traveller, so check your own route. Planning a trip to Tanzania for a wildlife safari, a climb up Mount Kilimanjaro, or a beach holiday in Zanzibar? One important question to answer before departure is whether you need a yellow fever vaccination certificate.
The short answer is: not every traveller needs one. Tanzania generally requires proof of yellow fever vaccination from travellers arriving from countries with a risk of yellow fever transmission, including travellers who have spent 12 hours or longer transiting through a risk country. Visitors arriving directly from countries without yellow fever transmission risk generally do not need the certificate for entry.
Because the requirement depends on your travel history and flight connections, check your complete itinerary before travelling. Sources include UK government travel advice and Tanzania Ministry of Health guidance.
Important: Entry rules can change. This guide is general information, not medical advice. Confirm the latest requirements with official sources before departure.
These are general points, not medical or legal advice. Official guidance takes precedence.
WHO NEEDS IT
You will generally need a valid International Certificate of Vaccination or Prophylaxis (ICVP), often called the yellow card, if you fall into one of these categories:
Check the official list: Tanzania’s Ministry of Health publishes the applicable country list and entry rules. Requirements can change, so check the latest official guidance before departure.
WHO DOES NOT
You generally do not need a yellow fever certificate if you are travelling directly to Tanzania from a country that is not considered at risk for yellow fever transmission and your itinerary does not include a qualifying transit through a risk country. For example, a traveller flying directly from the United Kingdom or the United States to Tanzania will generally not need the certificate solely for entry, provided their travel history does not trigger the requirement.
However, your nationality alone does not determine whether you need the vaccine. Your departure point, previous travel and flight connections matter. A traveller departing from a country without yellow fever risk may still need a certificate after a qualifying transit through a risk country. See the US CDC guidance for Tanzania.
WHICH COUNTRIES
Tanzania’s published guidance includes countries in Africa and South America where yellow fever transmission is a risk. Examples include:
Illustrative only: This is an illustrative list, not a complete or independently updated list of every country covered by Tanzania’s rules. Check the official guidance for the full list before travelling.
LAYOVERS
A layover can affect whether you need a yellow fever certificate, even if you do not intend to visit the country where you are connecting. Under Tanzania’s published rules, a transit of 12 hours or more in a yellow fever risk country can trigger the vaccination requirement. Before booking your flights, check:
If unsure: If you are unsure whether your route qualifies, confirm it with your airline or the nearest Tanzanian embassy or consulate before departure.
WHEN TO VACCINATE
If you need the vaccination for entry into Tanzania, arrange it well before your trip. For a first yellow fever vaccination, the international certificate generally becomes valid 10 days after vaccination. The International Health Regulations recognise a properly issued yellow fever certificate as valid for the vaccinated person’s lifetime, as described in the CDC Yellow Book.
Do not wait: Do not wait until the day you travel. Visit an authorised vaccination clinic or travel medicine provider, especially if you need advice about medical suitability or other travel vaccinations.
WITHOUT A CERTIFICATE
Travellers who are subject to the requirement but cannot provide a valid certificate may face problems at the border. Depending on the circumstances and the decision of the authorities, consequences can include refusal of entry, vaccination on arrival or a period of public health observation.
A medical exemption may be relevant for some travellers who cannot safely receive the vaccine. However, an exemption is not a guarantee of entry. Obtain appropriate medical documentation in advance and confirm whether it will be accepted by Tanzanian authorities.
Children and older adults may be subject to specific medical considerations or age-related exemptions. Seek advice from a qualified healthcare professional and verify the current entry rules for the traveller’s age.
ZANZIBAR
Zanzibar is part of the United Republic of Tanzania, and yellow fever entry requirements may apply depending on how you enter and your travel history. If you are flying internationally into Zanzibar, check whether your departure country or transit route triggers the requirement. If you are visiting mainland Tanzania first and then travelling to Zanzibar, confirm any applicable screening requirements with your airline and the relevant authorities.
Do not assume: Do not assume that booking a beach holiday rather than a mainland safari changes the rules. See our Zanzibar guide.
OTHER REQUIREMENTS
Yellow fever is only one part of preparing for a trip. Before departure, travellers should also:
Tailored advice: Health recommendations depend on your itinerary, activities, medical history and length of stay. A travel health clinic can provide advice tailored to your circumstances. See our Tanzania visa guide, travel insurance guide and what to know before traveling to Tanzania.
FAQ
Yellow fever certificate: quick answers to the questions travellers ask most.
No. Tanzania generally requires a yellow fever certificate from travellers arriving from countries with a yellow fever transmission risk, including qualifying long transits. Travellers arriving from countries without that risk generally do not need the certificate solely for entry.
Generally, no, provided you have not travelled through a qualifying yellow fever risk country in a way that triggers the requirement. Check your complete itinerary before departure.
Kenya is included in Tanzania’s published list of countries associated with the yellow fever requirement. A transit of 12 hours or more in a risk country can trigger the requirement. Confirm your exact itinerary with the relevant authorities before flying.
A properly completed international yellow fever vaccination certificate is generally valid for life, beginning 10 days after the first vaccination.
Tanzania’s published guidance describes possible vaccination on arrival for eligible travellers who lack the required proof. However, you should not rely on this option because entry restrictions or public health observation may apply. Getting vaccinated in advance is the safer approach when the requirement applies to you.
Consult the Tanzania Ministry of Health, the UK government’s Tanzania entry guidance, or a Tanzanian embassy or consulate. Your airline can also advise on document checks for your particular route.
FINAL ADVICE
Whether you are planning a Serengeti safari, visiting Ngorongoro Crater, climbing Mount Kilimanjaro or relaxing on Zanzibar’s beaches, check your yellow fever requirements before you leave home.
Remember: the key factors are where you are travelling from and whether your flight itinerary includes a qualifying transit through a yellow fever risk country. Confirm the latest requirements with official authorities before departure, and carry your vaccination certificate if it applies to you.
With your travel documents and health preparations in order, you can focus on enjoying your Tanzania adventure.
