Yellow Fever Vaccine Requirements by Country: Your 2026 International Travel Guide
Traveling to Africa, South America, or another international destination? Your yellow fever vaccination requirements may depend on more than the country you plan to visit.
A traveler flying directly from Washington, DC, to an international destination may face different vaccination requirements from someone traveling to the same country through an airport in a yellow fever risk area.
Even an extended layover can change what documentation is required.
At Maryland Primary & Urgent Care in Lanham, Maryland, we help international travelers understand these requirements before departure.
Our practice is an authorized yellow fever vaccination center, providing physician-led travel consultations, yellow fever vaccinations, and the official International Certificate of Vaccination or Prophylaxis (ICVP), commonly known as the Yellow Card.
Whether you’re traveling for business, tourism, family visits, or an extended stay abroad, understanding the entry requirements before you leave can help prevent avoidable problems at the airport or international border.

Which Countries Require Yellow Fever Vaccination in 2026?
There is no single worldwide yellow fever vaccination requirement.
Each country determines its entry requirements under the International Health Regulations.
Countries generally fall into three categories:
-
Countries requiring proof of yellow fever vaccination from all arriving travelers who meet the applicable age requirements.
-
Countries requiring proof only from travelers arriving from or transiting through certain yellow fever risk countries.
-
Countries without a yellow fever vaccination entry requirement, although vaccination may still be recommended for personal protection when traveling to areas with transmission risk.
This distinction is important because vaccination requirements and medical recommendations are not always the same.
For example, a country may recommend vaccination for travelers visiting particular regions without requiring every arriving traveler to present proof at the border.
Likewise, a country with little or no local yellow fever transmission may require documentation from travelers arriving from another country where the virus circulates.
The appropriate decision depends on your destination, complete itinerary, travel dates, and medical history.
Countries That Require Yellow Fever Vaccination from All Arriving Travelers
Some countries require proof of yellow fever vaccination from arriving travelers who meet their age criteria, regardless of whether they are coming directly from the United States.
According to the CDC Yellow Book reference list, examples include:
| Country | Region | Entry requirement |
|---|---|---|
| Angola | Africa | Proof required from eligible arriving travelers |
| Benin | Africa | Proof required from eligible arriving travelers |
| Burkina Faso | Africa | Proof required from eligible arriving travelers |
| Cameroon | Africa | Proof required from eligible arriving travelers |
| Côte d’Ivoire | Africa | Proof required from eligible arriving travelers |
| Democratic Republic of the Congo | Africa | Proof required from eligible arriving travelers |
| Ghana | Africa | Proof required from eligible arriving travelers |
| Mali | Africa | Proof required from eligible arriving travelers |
| Niger | Africa | Proof required from eligible arriving travelers |
| Sierra Leone | Africa | Proof required from eligible arriving travelers |
| Togo | Africa | Proof required from eligible arriving travelers |
| Uganda | Africa | Proof required from eligible arriving travelers |
| Bolivia | South America | Proof requirement listed by CDC; verify current application |
| French Guiana | South America | Proof requirement listed by CDC; verify current application |
These examples are drawn from the CDC Yellow Book’s reference table, last reviewed in September 2024. They are not a complete, continuously updated list of country rules.
Important: Entry requirements can change, and age thresholds or exemptions may differ. Travelers should verify the latest requirements through the CDC Yellow Book and the appropriate destination country’s embassy or consulate.
Countries with Conditional Yellow Fever Vaccination Requirements
Other countries require proof of vaccination only under specific travel circumstances.
Your recent travel history may determine whether you need an official Yellow Card.
These circumstances can include:
-
Arriving from a country with a recognized risk of yellow fever transmission.
-
Traveling through certain affected countries.
-
Spending an extended period in transit through an airport in a yellow fever risk country.
-
Entering after recent travel to a region covered by the destination’s vaccination rules.
Countries such as Kenya and Rwanda have route-dependent requirements rather than the universal entry rule that applies to some other African countries.
For example, a traveler entering Kenya directly from the United States may face different requirements from a traveler arriving after visiting a yellow fever endemic country.
Similarly, travelers moving between several African countries should not assume that the requirements for their first destination will apply throughout the journey.
A travel consultation should consider your entire route—not just your final destination.
Why Airport Layovers Can Change Yellow Fever Requirements
One of the most frequently overlooked aspects of international travel is the significance of airport transit.
Many travelers believe that remaining inside an airport means they have not entered the country and therefore cannot trigger vaccination requirements.
That assumption is not always correct.
Some destination countries include transit through yellow fever risk countries when determining whether vaccination documentation is required.
Certain countries apply specific transit-duration thresholds, while others consider whether travelers pass through immigration control or enter the country during a layover.
Example: A Multi-Country African Itinerary
Imagine you’re planning a business trip from Washington, DC, involving several African destinations.
Your first destination may not require a Yellow Card when arriving directly from the United States.
However, after traveling through another country with yellow fever transmission risk, your next destination may require proof of vaccination.
The same principle can apply to vacation itineraries involving multiple South American destinations.
Before departure, review:
-
Every country on your itinerary.
-
All airport connections.
-
The duration of each layover.
-
Whether you will leave the airport.
-
Each country’s vaccination entry requirements.
Do not rely exclusively on information provided during airline booking.

Understanding the International Yellow Fever Vaccination Certificate
The International Certificate of Vaccination or Prophylaxis (ICVP) is the official document used to establish proof of yellow fever vaccination for international travel.
Travelers commonly refer to it as the Yellow Card.
When a country requires proof of vaccination, an ordinary medical receipt or electronic vaccination record may not satisfy its documentation requirements.
The ICVP must be properly completed and validated according to international standards.
What Makes Your Yellow Card Valid?
An appropriately completed certificate contains important information, including:
-
The traveler’s identifying details.
-
The yellow fever vaccination information.
-
The date of vaccination.
-
The authorized healthcare professional’s signature.
-
The official stamp of the authorized yellow fever vaccination center.
The certificate becomes valid 10 days after the initial yellow fever vaccination and generally remains valid for the lifetime of the person vaccinated.
At Maryland Primary & Urgent Care, our authorized yellow fever vaccination service includes completion of the official vaccination certificate when the vaccine is administered.
We recommend keeping your original Yellow Card with your passport whenever traveling to a country that may request it.
Does Yellow Fever Vaccination Last for Life?
For most travelers, a single dose of yellow fever vaccine provides long-lasting protection.
Since July 2016, the International Health Regulations have recognized a properly completed yellow fever vaccination certificate as valid for the lifetime of the vaccinated person.
This replaced the previous international certificate validity period of 10 years.
Therefore, travelers who received yellow fever vaccination many years ago do not automatically need another dose simply because a decade has passed.
However, certain individuals may need additional vaccination based on their medical history or future exposure risk.
These may include some travelers with specific immune-related conditions or those entering particularly high-risk settings.
The decision should be individualized.
If you already have a Yellow Card from a previous vaccination, bring it to your travel consultation before considering another dose.
Unnecessary repeat vaccination should be avoided when existing documentation and clinical circumstances support continued protection.
What If You Cannot Safely Receive the Yellow Fever Vaccine?
Yellow fever vaccine is a live-attenuated vaccine and is not appropriate for every traveler.
Certain medical conditions, medications, and immune-related circumstances may increase the risk of serious vaccine-related complications.
Some travelers may require additional evaluation because of:
-
Significant immune suppression.
-
Certain immune-system disorders.
-
Previous severe reactions to vaccine components.
-
Pregnancy or breastfeeding considerations.
-
Older age at first vaccination.
-
Other established contraindications or precautions.
When vaccination is medically contraindicated or the risk outweighs the benefit, an authorized yellow fever vaccination provider may issue appropriate medical waiver documentation.
However, receiving a medical waiver does not guarantee admission to every destination.
Acceptance is determined by the receiving country’s authorities.
If a waiver is necessary, travelers should verify its acceptance with the destination’s embassy or consulate before departure.
This is particularly important for travelers with complex medical histories who are visiting countries with strict yellow fever entry requirements.
Why Yellow Fever Vaccination Requires More Than a Routine Injection
Yellow fever vaccination involves two separate considerations.
First, does your travel itinerary create a requirement for proof of vaccination?
Second, is vaccination medically appropriate for you?
These questions require different types of assessment.
A person may require a certificate to enter a destination but also have a medical condition that makes vaccination unsuitable.
Another traveler may not need a certificate for immigration purposes but may still benefit from vaccination because of exposure risk at the destination.
This is why travel medicine should not rely solely on a generic country list.
At Maryland Primary & Urgent Care, we consider the traveler’s itinerary, vaccination history, and relevant medical information when planning appropriate travel healthcare.
Our physician-led approach is designed to support informed decisions rather than unnecessary vaccination.

Frequently Asked Questions About Yellow Fever Vaccine Requirements
Which countries require yellow fever vaccination in 2026?
Several countries in Africa and South America require proof from arriving travelers, either universally within applicable age groups or based on recent travel through yellow fever risk countries. Requirements must be checked individually because they can change.
Do I need yellow fever vaccination to travel to Ghana?
Ghana is included in the CDC’s list of countries requiring proof of yellow fever vaccination from eligible arriving travelers. Check current entry requirements and age thresholds before departure.
Is yellow fever vaccination required for Kenya?
Kenya generally requires proof from travelers arriving from countries with yellow fever transmission risk. Requirements depend on the traveler’s route, rather than applying universally to every traveler arriving directly from the United States.
Is the yellow fever vaccine required for Brazil?
Yellow fever vaccination is recommended for travel to various regions of Brazil, but Brazil does not generally require an ICVP for entry. Other countries visited before or after Brazil may have separate rules, so the complete itinerary matters.
Can an airport layover trigger a yellow fever vaccination requirement?
Yes. Certain countries consider transit through yellow fever risk countries when determining whether vaccination documentation is required. The specific rule depends on the destination and circumstances of transit.
How long is a Yellow Card valid?
Under the International Health Regulations, a properly completed certificate becomes valid 10 days after primary vaccination and remains valid for life.
Do I need another yellow fever vaccine after 10 years?
Most travelers do not require a routine booster solely because 10 years have passed. Additional doses may be appropriate for selected individuals based on medical or exposure-related considerations.
Can I get a yellow fever vaccine if I have a chronic medical condition?
That depends on your specific condition, medications, immune status, and other risk factors. A physician should determine whether vaccination is medically appropriate.
What happens if I lose my Yellow Card?
Contact the original vaccination provider. If an appropriate record of previous vaccination is available, the provider may be able to assist with replacement documentation.
