Yellow fever vaccination is one of the most critical requirements for international travellers departing from or transiting through Kenya. The vaccine protects against yellow fever, a serious viral disease transmitted by infected mosquitoes that can cause severe illness and, in some cases, death. Whether you need the vaccine for travel, work, or immigration purposes, this guide covers everything you need to know about the yellow fever vaccination in Nairobi.
What Is Yellow Fever?
Yellow fever is an acute viral haemorrhagic disease transmitted by infected Aedes and Haemagogus mosquitoes. The disease occurs primarily in tropical regions of Africa and South America. Kenya is classified as a yellow fever endemic country, meaning the virus circulates naturally in certain parts of the country. However, yellow fever vaccination is not recommended for travel to North Eastern Province, Kilifi, Kwale, Lamu, Malindi, Tana River, and the cities of Nairobi and Mombasa, as these are not considered risk areas. All other regions of Kenya are classified as yellow fever risk areas where vaccination is recommended.
Yellow fever transmission in East Africa is less predictable than in West Africa, with long periods between outbreaks. The WHO reported a yellow fever outbreak in Kenya in 2022, and recent outbreaks in the DRC, South Sudan, and Nigeria have prompted stricter enforcement of certificate checks at borders across the region.
Symptoms range from mild fever and headache to severe illness involving jaundice (yellowing of the skin, which gives the disease its name), bleeding, organ failure, and potentially death. There is no specific antiviral treatment for yellow fever, which makes vaccination the most effective form of prevention.
Who Needs the Yellow Fever Vaccine?
The yellow fever vaccine is required or recommended for several groups of people:
- International travellers departing from Kenya to countries that require proof of yellow fever vaccination upon entry
- Travellers arriving in Kenya from other yellow fever endemic countries
- Immigration applicants for countries that mandate yellow fever vaccination as part of the immigration medical process
- People living in or travelling to yellow fever risk areas within Kenya
- Healthcare and laboratory workers who may be exposed to the yellow fever virus
Countries That Require Yellow Fever Vaccination
Dozens of countries require travellers from Kenya to present a valid yellow fever vaccination certificate. Some of the most commonly travelled destinations with this requirement include:
- South Africa
- India
- China
- Saudi Arabia (for Hajj and Umrah)
- Brazil
- Thailand
- Australia
- Uganda and Rwanda (mandatory for all arriving travellers)
- Tanzania (checked occasionally)
- Many West and Central African countries
Recent outbreaks in the DRC, South Sudan, and Nigeria have prompted stricter enforcement of yellow fever certificate requirements across the continent.

The Yellow Fever Vaccination Certificate (Yellow Card)
Upon receiving the yellow fever vaccine, you will be issued an International Certificate of Vaccination or Prophylaxis (ICVP), commonly known as the yellow card. Key facts about this certificate:
- The certificate becomes valid 10 days after vaccination for first-time recipients
- Since 11 July 2016, the WHO declared that a single dose of yellow fever vaccine provides lifelong immunity, meaning the certificate is valid for life and does not expire — no booster is required
- The certificate must be issued at a WHO-approved vaccination centre
- It must include your name, date of birth, passport number, vaccine batch number, and the stamp of the issuing centre
- A lost certificate can be re-issued if vaccination records are available at the administering centre
Always keep your yellow card with your passport when travelling internationally. Without it, you may be denied boarding, quarantined upon arrival, or required to be vaccinated at the airport.
Potential Side Effects
The yellow fever vaccine is generally well-tolerated. Most people experience either no side effects or only mild reactions. Common side effects include:
Mild Side Effects (Common)
- Soreness, redness, or swelling at the injection site
- Low-grade fever
- Headache and muscle aches
- Fatigue lasting 1-2 days
These symptoms typically appear within a few days of vaccination and resolve on their own within a week.
Serious Side Effects (Rare)
In very rare cases (approximately 1 in 250,000 doses), more serious reactions can occur:
- Severe allergic reaction (anaphylaxis) – Usually occurs within minutes of vaccination. This is why you are asked to wait at the clinic for 15-30 minutes after receiving the vaccine.
- Yellow fever vaccine-associated viscerotropic disease (YEL-AVD) – An extremely rare condition where the vaccine virus causes organ damage similar to the disease itself.
- Yellow fever vaccine-associated neurotropic disease (YEL-AND) – A rare neurological reaction that can include encephalitis.
Who Should NOT Get the Yellow Fever Vaccine?
The vaccine is contraindicated for certain groups. You should discuss alternatives with your doctor if you:
- Are allergic to eggs or any component of the vaccine
- Have a severely weakened immune system (due to HIV/AIDS, chemotherapy, or immunosuppressive medications)
- Are pregnant or breastfeeding (unless the risk of yellow fever exposure is very high)
- Are an infant under 6 months of age (the vaccine is generally not recommended for children under 9 months)
- Are aged 60 or older and receiving the vaccine for the first time (increased risk of serious side effects)
- Have a thymus disorder or have had your thymus removed
If the vaccine is contraindicated, your doctor can provide a medical waiver letter that may be accepted by some countries in lieu of the certificate.
How to Prepare for Your Yellow Fever Vaccination
- Schedule your appointment at least 10 days before travel, as the certificate only becomes valid after this period.
- Bring your passport – your passport number will be recorded on the yellow card.
- Bring your existing yellow card if you have received the vaccine previously.
- Inform the healthcare provider about any allergies, medications, or medical conditions.
- Plan to wait 15-30 minutes after vaccination for observation.
