FREQUENT FLYER GLOSSARY
What is a yellow fever certificate?
A yellow fever certificate is an official vaccination record that a country may ask to see at its border from a traveller arriving from an area where yellow fever is a transmission risk. [3] It is a public-health entry document, listed alongside visa and passport checks rather than as part of them, and the rule behind it is made by the destination country rather than by the airline. [3]

Key takeaways
- A yellow fever certificate proves that a traveller has had a yellow fever vaccination, and a destination country may require it before entry. [3]
- Kenya requires the certificate from travellers arriving from a country listed as a yellow fever transmission risk, and Kenya's own authorities set and enforce that rule. [3]
- Published entry-requirement tools are snapshots: the one Emirates links to is supplied by the International Air Transport Association (IATA), may change at short notice and is described as a guide only. [6]
- Vaccination is arranged through designated health sites; Canada's public health agency publishes a directory of yellow fever vaccination centres. [5]
Why do countries ask for a yellow fever certificate?
Yellow fever is an acute flavivirus infection spread by the bite of an infected mosquito. [2] The certificate is the record a traveller presents to show that a yellow fever vaccination has been given, which is what a destination such as Kenya accepts as proof when someone arrives from a risk area. [3]
In the United Kingdom, yellow fever immunisation information for public health professionals is published by the UK Health Security Agency as chapter 35 of the green book, and that page was last updated on 6 February 2024. [2] The chapter itself is available to view or download from the National Travel Health Network and Centre (NaTHNaC). [2]
When do you need a yellow fever certificate to enter Kenya?
The UK Foreign, Commonwealth & Development Office (FCDO) states that to enter Kenya you must have a certificate to prove you have had a yellow fever vaccination if you are coming from a country listed as a transmission risk. [3] In that guidance the trigger is the country the traveller arrives from. [3]
The FCDO page is written for people travelling on a full ‘British citizen’ passport from the UK, and it is based on the UK government's understanding of Kenya's current rules for the most common types of travel. [3] The authorities in Kenya set and enforce entry rules, and travellers who are unsure how those requirements apply to them are directed to contact the Kenyan High Commission in the UK. [3] For full details of medical entry requirements and recommended vaccinations, the guidance points readers to TravelHealthPro's Kenya guide. [3]
The certificate sits alongside other Kenyan formalities rather than replacing them: the same guidance says a passport must have an expiry date at least six months after the date of arrival and at least two blank pages, and that an electronic travel authorisation must be applied for online in advance, with the local authorities recommending an application at least two weeks before departure. [3]
Who sets yellow fever certificate rules?
Yellow fever certificate rules are national rules. Kenya's own authorities set and enforce its entry requirements, and the FCDO page describes those requirements for British travellers rather than creating them. [3] The Public Health Agency of Canada takes a similar directory approach and points travellers to country-specific travel advice and advisories covering safety, security, local laws, customs and entry requirements. [5]
Airlines check travel documents before boarding, but they do not set the underlying requirement. Emirates tells travellers that it is their responsibility to carry the proper travel documents and to check the entry requirements for their trip before travelling. [6] The visa and passport tool on Emirates' site is provided by IATA, is available in English only, and may change at short notice; Emirates describes it as a guide and tells travellers to check with the relevant authorities for their destination countries, adding that holders of non-standard passports and travel documents may have different entry requirements. [6]
Where can you get a yellow fever vaccination?
Vaccination is arranged through health providers rather than through airlines. The Public Health Agency of Canada publishes a directory that helps travellers find a health care site in their area that has been designated a yellow fever vaccination centre. [5] The same section of its site collects travel health notices on potential risks to travellers and the recommended ways to reduce them. [5]
For clinicians in the UK, the yellow fever immunisation chapter is available to view or download from NaTHNaC. [2]
Exceptions and limits
- Arrival route matters. Kenya's certificate requirement is tied to arriving from a country listed as a transmission risk. [3] Travellers who are unsure whether that applies to their itinerary are directed to the Kenyan High Commission in the UK. [3]
- One requirement among several. Passport validity, blank pages and the electronic travel authorisation are separate Kenyan conditions that apply on top of the vaccine certificate. [3]
- Guidance is a snapshot. IATA-supplied entry information on Emirates' site is a guide, may change at short notice, and can differ for holders of non-standard passports and travel documents. [6]
- Different passport holders. The FCDO's Kenya advice is written for full ‘British citizen’ passports travelling from the UK, so other travellers need the position that applies to their own documents. [3]
- Clinical guidance is not a border rule. The UK Health Security Agency chapter is yellow fever immunisation information for public health professionals, while the certificate requirement itself comes from the destination country. [2] [3]
Frequently asked questions
Do I need a yellow fever certificate to travel to Kenya?
You must have a certificate proving yellow fever vaccination if you are coming to Kenya from a country listed as a transmission risk. [3] The FCDO's page is written for travellers on a full British citizen passport departing from the UK. [3]
Who decides whether a yellow fever certificate is required?
The destination country does. Kenya's authorities set and enforce its entry rules, and the FCDO summarises them for travellers. [3]
Where can I find a yellow fever vaccination centre?
The Public Health Agency of Canada lists health care sites in Canada that have been designated as yellow fever vaccination centres. [5] In the UK, the yellow fever immunisation chapter is available to view or download from NaTHNaC. [2]
Can the requirement change before I fly?
Yes. Emirates notes that the IATA-supplied entry information on its site may change at short notice and is intended only as a guide, so travellers are told to check with the relevant authorities. [6]
Who should I ask if I am unsure whether the rule applies to me?
The FCDO directs travellers who are unsure how Kenya's requirements apply to them to contact the Kenyan High Commission in the UK. [3]
