Who should have it
Travellers visiting areas where yellow fever is present, particularly parts of sub-Saharan Africa and tropical South America. It’s also required for entry to certain countries, either because of yellow fever risk there, or if you’re arriving from a country where it’s present, so you may need proof of vaccination to travel.
How many doses
For most people, a single dose gives long-lasting protection, usually considered to provide lifelong immunity. Your prescriber will confirm whether you need it and whether a booster applies in your circumstances.
Possible side effects
Side effects are usually mild and may include soreness, redness or swelling at the injection site, headache, tiredness, muscle aches, or a mild temperature in the days after vaccination. Your prescriber will discuss the benefits and any risks with you beforehand.
Additional precautions
The vaccine doesn’t remove the need to avoid mosquito bites, use insect repellent, cover up, and take care especially during the day, when the mosquitoes that spread yellow fever tend to bite. The vaccine isn’t suitable for everyone, so a prescriber will check it’s right for you.
About the disease
Yellow fever is a serious viral infection spread by infected mosquitoes. It can range from a mild flu-like illness to severe disease affecting the liver and other organs, which is why prevention through vaccination is so important.
