Yellow Fever Certificate for East Africa: Who Needs One at the Border?

Planning a safari in East Africa involves more than booking flights, accommodation and wildlife activities. You must also understand the health documents required when entering different countries. One document that frequently causes confusion is the yellow fever vaccination certificate.

Yellow fever certificate requirements in East Africa vary depending on your destination, previous travel history and the countries you have recently visited or passed through.

Uganda, Kenya, Rwanda and Tanzania do not apply identical entry requirements. A traveller arriving directly from Europe may face different conditions from someone travelling between several African countries.

Importantly, Uganda changed its entry requirements in October 2026, removing the general requirement to present a yellow fever vaccination certificate.

What Is a Yellow Fever Vaccination Certificate?

A yellow fever vaccination certificate is an internationally recognised document confirming that a person has received a yellow fever vaccine.

Its official name is the International Certificate of Vaccination or Prophylaxis.

The certificate is commonly called the yellow card.

It records important information, including:

• Traveller’s name.

• Date of vaccination.

• Vaccine details.

• Vaccination centre information.

• Authorised medical signature and stamp.

Some countries require travellers to present this certificate when arriving from areas where yellow fever transmission occurs.

Why Is the Certificate Important?

Yellow fever is a viral disease transmitted through bites from infected mosquitoes.

Symptoms may include fever, headache, muscle pain, nausea and weakness.

Severe infections can cause serious complications.

Vaccination provides effective protection and helps reduce the risk of disease spreading between countries.

Yellow Fever Certificate Requirements in East Africa

Each East African country establishes entry requirements based on public health considerations.

The following table summarises the main rules.

Requirements may change during disease outbreaks.

Always confirm the conditions applying to your complete travel itinerary.

1. Yellow Fever Requirements for Uganda

Uganda previously required international visitors to present proof of yellow fever vaccination.

However, this requirement changed in 2026.

Uganda’s Updated Entry Rules

On 2 October 2026, Uganda’s Directorate of Citizenship and Immigration Control announced that a yellow fever vaccination certificate was no longer mandatory for entry into Uganda.

The requirement was also removed from the official electronic visa application process.

This means travellers entering Uganda are no longer generally required to present the certificate at the border.

Should You Still Get Vaccinated?

Although the certificate is no longer mandatory for Ugandan entry, vaccination remains an important health consideration.

Yellow fever transmission risk exists in Uganda.

Travellers should obtain individual medical advice before departure.

Your age, medical history, vaccination status and planned destinations may influence the recommendation.

You may also need the certificate when travelling onwards to another country.

2. Yellow Fever Requirements for Kenya

Kenya requires a valid yellow fever vaccination certificate from travellers arriving from countries where yellow fever transmission occurs.

The requirement is based mainly on recent travel history rather than nationality alone.

Who Needs the Certificate?

You may need a certificate if you arrive in Kenya after visiting a yellow fever risk country.

For example, someone travelling from Uganda to Kenya may be asked to present proof of vaccination.

Travellers arriving directly from countries without yellow fever transmission risk may not require the certificate.

However, your complete route matters.

Arriving at Kenyan Borders

Health officials may check vaccination documents at international airports and authorised land borders.

Travellers should keep certificates accessible alongside passports and other documents.

If you are travelling through several countries, confirm whether your transit history affects the requirement.

3. Yellow Fever Requirements for Rwanda

Rwanda requires proof of yellow fever vaccination from travellers arriving from countries considered to have yellow fever transmission risk.

The country also applies additional precautions when travellers arrive from locations experiencing active outbreaks.

Travellers Arriving From Low-Risk Countries

Visitors arriving directly from countries without yellow fever transmission risk generally do not need a certificate.

For example, someone travelling directly from a European country without yellow fever risk may not require proof of vaccination.

Travellers Arriving From Risk Countries

Travellers entering Rwanda from affected countries may need a valid certificate.

This can include visitors travelling from Uganda or other countries with recognised transmission risk.

Additional health screening may apply during outbreaks.

Rwanda Gorilla Trekking Visitors

If your safari combines Rwanda with another East African country, check your route carefully.

The certificate requirement may differ depending on which country you visit first.

4. Yellow Fever Requirements for Tanzania

Tanzania requires yellow fever vaccination certificates from travellers arriving from designated countries with transmission risk.

Its rules also consider certain airport transit situations.

Arriving From Yellow Fever Risk Countries

Travellers entering Tanzania from countries such as Uganda or Kenya may need valid vaccination certificates.

This includes visitors combining wildlife safaris across several destinations.

Transit Through Risk Countries

Tanzania’s official guidance identifies airport transit lasting 12 hours or longer in a yellow fever risk country as a circumstance that can trigger the vaccination requirement.

Shorter transit arrangements may be treated differently.

However, travellers should confirm the rules applying to their exact flight connection.

Visiting Zanzibar

Zanzibar is part of Tanzania.

Travellers should follow the relevant Tanzanian health entry requirements and verify any additional arrival procedures.

How Long Is a Yellow Fever Certificate Valid?

A yellow fever vaccination certificate generally becomes valid 10 days after the initial vaccination.

Under international health regulations, a valid certificate normally remains effective for the vaccinated person’s lifetime.

Do You Need a Booster?

Routine yellow fever booster vaccination is generally unnecessary for most people.

A single dose usually provides long-lasting protection.

However, certain medical circumstances may require individual assessment.

Consult a qualified healthcare professional if you are uncertain about your vaccination history.

Who May Be Exempt From Yellow Fever Vaccination?

Yellow fever vaccination is not suitable for everyone.

Certain travellers may require medical assessment before receiving the vaccine.

Infants and Young Children

Age restrictions apply to yellow fever vaccination.

The vaccine is generally not recommended for infants younger than six months.

Children between six and eight months require special medical consideration.

Country entry rules may also provide age-based exemptions.

Pregnant Women

Pregnant travellers should obtain medical advice before vaccination.

A healthcare professional must assess the potential risks and benefits.

People With Certain Medical Conditions

Some individuals with severe immune system problems, thymus disorders or serious allergies may be unable to receive the vaccine safely.

Older adults receiving their first yellow fever vaccination may also require additional assessment.

Medical Exemption Certificates

Travellers who cannot receive the vaccine for valid medical reasons may qualify for a medical waiver.

However, a waiver does not automatically guarantee admission.

Immigration and health authorities may apply additional precautions.

Yellow Fever Requirements for Multi-Country Safaris

Travellers visiting several East African countries should consider the entire journey.

Example 1: Uganda and Rwanda Safari

A traveller arriving in Uganda may not need a yellow fever certificate for Ugandan entry.

However, Rwanda may require the certificate when the traveller subsequently enters from Uganda.

Example 2: Kenya and Tanzania Safari

A traveller entering Tanzania after visiting Kenya may need proof of vaccination.

This requirement can apply even when the traveller originally arrived in Kenya from a country without yellow fever risk.

Example 3: Uganda, Kenya and Tanzania Safari

A traveller visiting all three countries should check vaccination requirements before departure.

Although Uganda no longer requires the certificate for general entry, Kenya and Tanzania may request it based on the travel route.

Practical Tips for Travellers

Preparing your health documents early helps prevent unnecessary delays.

Follow these recommendations:

• Check vaccination requirements before booking flights.

• Review the rules for every country on your itinerary.

• Arrange vaccination at least 10 days before travel when required.

• Keep your original vaccination certificate accessible.

• Carry a photograph or electronic copy as backup.

• Confirm medical exemptions before departure.

• Consult a travel health professional about recommended vaccinations.

• Check requirements again shortly before travelling.

Remember that yellow fever vaccination requirements and malaria prevention recommendations are different matters.
