This is official-guidance signposting, not medical advice. See a travel clinic 4–8 weeks before departure for advice tailored to your health, age, pregnancy status, itinerary and trip length. Authoritative sources: CDC Travelers' Health (wwwnc.cdc.gov/travel/destinations/traveler/none/kenya), WHO, your national travel-health service (e.g. UK TravelHealthPro, Canada travel.gc.ca), and Kenya Ministry of Health (health.go.ke).
The critical distinction
| Category | What it means |
|---|---|
| Legal entry requirement | You can be refused entry without it. For Kenya, this is essentially the yellow fever certificate for travelers coming from at-risk countries (see below). |
| Official health guidance | Strongly recommended by CDC/WHO for your safety (most routine + travel vaccines, malaria prevention). |
| Optional precautions | Sensible extras based on your itinerary. |
Yellow fever (the one that can be a legal requirement)
- Kenya requires a yellow fever vaccination certificate from travelers arriving from, or having transited (>12 hours) through, countries with risk of yellow fever transmission (a list of ~35+ countries incl. much of tropical Africa and parts of South America). Applies to travelers generally over 1 year of age.
- Coming directly from a country with no yellow fever risk (e.g. USA, UK, most of Europe)? The certificate is generally not required for entry — but is often medically recommended for parts of Kenya.
- The certificate is valid for life (since 2016) — no boosters needed.
- Note the reverse: Kenya is itself considered to have yellow fever risk in parts, so some onward countries (e.g. South Africa, some others) may require proof of yellow fever vaccination when you travel there from Kenya. Plan ahead if Kenya is one leg of a multi-country trip.

Recommended vaccines (per CDC/WHO — confirm with your clinic)
Routine (be up to date): MMR, Tdap (tetanus/diphtheria/pertussis), polio, chickenpox, influenza, COVID-19, pneumonia/shingles as age-appropriate.
Commonly recommended for Kenya:
- Hepatitis A — food/water borne
- Typhoid — food/water borne
- Hepatitis B — recommended for many travelers
- Yellow fever — recommended for most itineraries (see above); not generally recommended if only visiting Nairobi city, the North Eastern region, or the coast strictly per risk maps — your clinic decides.
- Rabies — considered for longer stays, rural/remote travel, working with animals, or travel with children
- Meningococcal (meningitis) — considered, especially in the dry season (roughly Dec–June)
- Cholera — considered for some rural/at-risk areas

Malaria
- Malaria is present in most of Kenya below ~2,500 m and is chloroquine-resistant — so chloroquine is not effective; clinics prescribe alternatives (e.g. atovaquone-proguanil, doxycycline, or mefloquine — a clinical decision).
- Higher-risk areas (year-round): Maasai Mara, Amboseli, Tsavo, Samburu, Laikipia lowlands, and the whole coast (Mombasa, Diani, Watamu, Malindi, Lamu).
- Low-risk areas: Nairobi city and the highlands above ~2,500 m.
- Prevention = pills + bites-avoidance: take prescribed antimalarials as directed and use DEET/picaridin repellent, cover up at dusk/dawn, and sleep under a treated mosquito net.
- Seek medical care promptly for fever during or up to a year after travel.

Other health preparation
- Prescription medication: bring enough for your whole trip in original labeled packaging, plus a copy of the prescription / a doctor's letter (essential for injectables and controlled medicines). Check that your medication is legal in Kenya — some controlled drugs need documentation or are restricted; when in doubt, confirm with a Kenyan embassy.
- Travel & medical-evacuation insurance: strongly recommended. For safaris and remote areas, ensure it covers medical evacuation (e.g. AMREF Flying Doctors operate air evacuation in the region). Confirm coverage for adventure activities (diving, climbing).
- Food & water: don't drink tap water — use bottled/filtered/boiled water; be cautious with ice, unpeeled raw produce, and undercooked food. (See practical Q&A.)
- Altitude: Nairobi sits at ~1,795 m; Mt Kenya and the highlands are far higher. Ascend gradually; know altitude-sickness signs if climbing.
- Heat & sun & hydration: high UV near the equator — sunscreen, hat, water.
- Pregnancy, chronic conditions, disability-related needs: discuss individually with your doctor well ahead — some vaccines and antimalarials aren't suitable in pregnancy, and remote areas have limited medical facilities.
- Allergies: carry your own supplies (e.g. epinephrine auto-injectors) with documentation; allergen labeling is inconsistent.
Where to get vaccines / advice
- A travel clinic or travel-health pharmacy in your home country (book 4–8 weeks ahead).
- Yellow fever must be given at an authorized yellow fever vaccination center (they issue the official certificate).
Do not treat this as individualized medical advice. Confirm everything with a qualified travel-health professional and the current CDC/WHO/Kenya MoH guidance close to your travel date.
Sensitive-topic note: none here, but if you're managing a serious health condition, involve your own doctor early.
