🦠 What is Yellow Fever?
Yellow Fever is a mosquito-borne viral infection found in tropical areas of Africa and Central/South America.
It’s transmitted by Aedes or Haemagogus mosquitoes—the same type that spreads dengue and Zika.
While most infections are mild, severe Yellow Fever can lead to liver failure, internal bleeding, and death. The CDC estimates a case-fatality rate of 30–60% among severe cases.
There’s no specific treatment. Prevention through vaccination and mosquito bite protection is key.
🌎 Where is the Yellow Fever Vaccine Required or Recommended?
Understanding where the Yellow Fever vaccine is needed can be tricky. Requirements fall into two main categories:
| Requirement Type | Countries (Examples) | Notes |
|---|---|---|
| Mandatory for all travelers | Angola, Bolivia, Democratic Republic of the Congo, Ghana, Uganda, + more. | All incoming travelers must show proof, regardless of origin. |
| Mandatory if arriving from a Yellow Fever risk country | South Africa, Kenya, Panama, Tanzania, India, China + more. | Transit rules may apply; check all layovers. |
Note: Even a short layover in a risk country can trigger vaccination requirements for your destination. Check the country specific yellow fever requirement at CDC Yellow Fever.
Example: Flying from Canada to Kenya (no general requirement) with a 6-hour layover in Ethiopia (Yellow Fever risk) may mean Kenya requires your Yellow Card.
Why it matters:
- Mandatory: No vaccine = denied boarding, refused entry, or forced vaccination/quarantine.
- Recommended: Even if not legally required, vaccination protects against serious illness in high-risk areas.

⏰ When Should You Get the Yellow Fever Vaccine?
Timing is critical:
- At least 10 days before travel: Immunity develops, and your International Certificate of Vaccination (Yellow Card) becomes valid.
- Single dose = lifelong protection: Boosters are generally unnecessary as per WHO guidelines. ACIP suggests a booster dose can be considered for certain travelers.
Tip: Book your appointment 4–6 weeks before departure, especially if you need other vaccines or medications like malaria prophylaxis or travel health kits.
🧾 The Yellow Card (ICVP)
When you get vaccinated, you’ll receive the International Certificate of Vaccination or Prophylaxis (ICVP)—the famous Yellow Card.
- It’s official proof that you’ve been vaccinated at a WHO-designated centre.
- It becomes valid 10 days after vaccination and remains valid for life (unless damaged or lost).
- You must present it at immigration in certain countries.
📸 Tip: Keep a photo of your Yellow Card in your phone and store the original with your passport but in a separate pocket for safekeeping.
⚕️ Who Should Not Get the Yellow Fever Vaccine? (Contraindications & Precautions)
According to the CDC and WHO, the Yellow Fever vaccine is safe and effective for most healthy adults.
However, certain groups should avoid or delay vaccination depending on individual health risks.
🚫 Contraindications (Should Not Be Vaccinated)
- Infants under 6 months old
- People with severe allergic reactions to egg proteins or any vaccine component
- Those with severe immunodeficiency (e.g., due to HIV/AIDS, cancer chemotherapy, or organ transplant)
- Individuals with a history of thymus disorders (e.g., thymoma, myasthenia gravis, thymectomy)
⚠️ Precautions (Vaccinate Only if Risk Outweighs Risk of Vaccine)
- Infants 6–8 months old
- Pregnant or breastfeeding individuals (unless travel to a high-risk area is unavoidable)
- Adults ≥60 years old, due to increased risk of severe side effects
- People with mild egg allergies (should discuss with a travel medicine provider)
🩺 Tip: If vaccination is unsafe for you, a licensed travel clinic can issue a medical waiver letter (sometimes accepted by border officials in place of vaccination proof).
💉 Common & Rare Side Effects
Typical reactions:
- Redness or soreness at injection site
- Mild headache, fever, or fatigue
Rare but serious (per CDC):
- Yellow Fever vaccine–associated viscerotropic disease (YEL-AVD): severe organ failure, very rare (0.3 to 0.5 per 100,000 increased to 1.2 to 2.1 per 100,000 for >=60 years old)
- Yellow Fever vaccine–associated neurologic disease (YEL-AND): brain inflammation, also very rare (0.8 to 1 per 100,000 increased to 2.2 to 6.2 per 100,000 for >=60 years old)
Note: These severe side effects are extremely uncommon. For most travelers, the benefits far outweigh the risks—especially when traveling to endemic regions.
🦟 Yellow Fever Prevention Beyond the Vaccine
Even if you’re vaccinated, reducing mosquito bites is key—especially during outbreaks.
Smart Protection Tips:
- Use repellents with DEET (20–30%) or picaridin.
- Wear light-colored, long-sleeved clothing during daytime (Aedes mosquitoes bite during daylight).
- Stay in air-conditioned or screened accommodations.
- Use permethrin-treated clothing and bed nets in rural or jungle areas.
