Everything You Need to Know About the Yellow Fever Vaccine
What Is Yellow Fever?
Yellow fever is a viral disease transmitted by infected mosquitoes, mainly in parts of Africa
and South America. It can cause mild flu-like symptoms or lead to severe complications,
including organ failure and death. Since there’s no specific treatment, vaccination is the best
protection.
Why Get the Yellow Fever Vaccine?
The yellow fever vaccine is a safe and effective way to prevent the disease. Many countries
require proof of vaccination (a Yellow Card or International Certificate of Vaccination) for
travelers coming from affected areas.
Who Needs the Vaccine?
- Travelers going to or from regions with yellow fever risk
- Residents in high-risk areas
- Some workers, such as healthcare and lab personnel handling the virus
Who Should Avoid the Vaccine?
- Infants under 6 months old
- People with severe egg allergies
- Those with weakened immune systems (e.g., HIV/AIDS, cancer patients)
- Pregnant or breastfeeding women (unless travel is essential)
How Long Does It Last?
One dose provides lifelong immunity for most people.
Possible Side Effects
Most people have mild reactions, such as:
✅ Low fever
✅ Soreness at the injection site
✅ Headache or muscle pain
Severe reactions are rare but can include allergic reactions or neurological effects.
Travel Requirements & Yellow Card
Some countries won’t let you in without proof of vaccination. Make sure to get vaccinated at
least 10 days before travel and carry your Yellow Fever Certificate.
Where to Get Vaccinated?
Vaccines are available at certified travel clinics, hospitals, and some pharmacies. Always
check if your destination requires vaccination before traveling.
