The Centers for Disease Control and Prevention updated its Kenya travel notice on 22 May 2026. All US travellers must receive a yellow fever booster if their original vaccination is older than ten years. The requirement takes effect for departures on or after 15 June.
Kenyan authorities will enforce the rule at all international airports and land borders. The CDC cited recent outbreaks in neighbouring countries as a contributing factor. Travellers without valid documentation face potential quarantine or denial of entry.
Booster shots are available at certified yellow fever vaccination centres across the United States. The single-dose booster provides lifelong protection according to current medical consensus. Cost averages 120 USD and is not covered by most insurance plans.
Parents travelling with children should verify vaccination records before booking flights. The CDC maintains its existing malaria prophylaxis recommendations for Kenya. Updated guidance appears on the CDC Travelers’ Health website.
Airlines flying to Nairobi and Mombasa have begun notifying passengers of the new requirement. Travel clinics report increased bookings for booster appointments. The policy aligns with similar measures already in place for several West African nations.
Health officials recommend scheduling the booster at least two weeks before departure. Digital vaccination certificates accepted by Kenya include the CDC’s VaxCheck app. Further updates will be issued if the epidemiological situation changes.
