Whether you're planning a safari in Africa, exploring South America's natural wonders, or travelling overseas for work, it's worth checking if yellow fever vaccination is part of your travel preparations.

Yellow fever is a viral infection spread by infected mosquitoes. While many people experience mild symptoms or none at all, some can develop:

• fever
• headache  
• muscle aches
• nausea
• vomiting

In rare cases, the illness can become severe and lead to complications affecting multiple organs. Fortunately, vaccination is highly effective and remains the best way to protect yourself against the disease.  

Why Is Yellow Fever Vaccination Important?

If you are travelling to countries where yellow fever is present, vaccination may be recommended or required depending on your destination and travel itinerary. Beyond protecting your own health, vaccination also helps prevent the disease from being brought into countries that are free from yellow fever, such as Singapore.  

A single dose of the vaccine provides lifelong protection for most travellers, and the International Certificate of Vaccination or Prophylaxis (ICVP), commonly known as the yellow fever vaccination certificate, remains valid for life.  

Plan Ahead Before You Travel

Note: The yellow fever vaccination certificate only becomes valid 10 days after vaccination. 

If you're travelling soon, don't leave your vaccination appointment until the last minute. Planning ahead can help you avoid unnecessary travel disruptions and ensure your documentation is ready when you need it.  

It is also a good idea to speak with your doctor before vaccination. Your doctor can assess your travel plans, review your medical history, and advise whether the vaccine is suitable for you.  

Returning to Singapore: What You Need to Know

Singapore remains free from yellow fever. To protect public health, travellers arriving from countries with a risk of yellow fever transmission may be required to present a valid yellow fever vaccination certificate upon arrival.

• Arriving from risk countries: A valid certificate may be required at the checkpoint.
• Airport transits: The requirement may also apply to travellers who have spent extended periods in transit in these countries.  

Entry requirements and measures may change over time, so travellers should always refer to the latest guidance from the Immigration & Checkpoints Authority (ICA) and Communicable Diseases Agency (CDA) before travelling.  

Travel Smart, Travel Confidently

Before your next trip, take a few minutes to review your itinerary, including any transit stops. A travel health consultation several weeks before departure can help ensure that you have the necessary vaccinations and documentation for a safe and hassle-free journey.
