Yellow Fever Vaccinations

About Yellow Fever

Yellow fever is a serious infection spread by mosquitoes. It is found in parts of Africa, South America, Central America and Trinidad in the Caribbean.  The mosquitoes that have the virus are usually found in towns and rural areas and tend to bite during the day.

The Yellow Fever vaccine is recommended if you are travelling to:

  • An area where yellow fever is found
  • A country that requires you to have a certificate proving you have been vaccinated against Yellow Fever.

You need to have the vaccine at least 10 days before travelling to provide sufficient time for it to work. Your certificate of vaccination will only be valid after this time.

You should ideally wait at least 4 weeks before having the Yellow Fever vaccine if you, or your child has had the MMR vaccine. Medwyn Travel Clinic is a registered Yellow Fever vaccination centre. The vaccine and certificate are only available from registered yellow fever vaccination centres.


Try to avoid being bitten by mosquitos, even if you have been vaccinated.

  • Use mosquito nets when sleeping
  • Wear clothes that cover your arms and legs
  • Applying insect repellent containing 30% to 50% DEET (diethyltoluamide)
  • Avoid areas near stagnant or non-flowing water.


The first symptoms of Yellow Fever usually develop 3 to 6 days after being infected:-

  • High temperature
  • Headache
  • Feeling sick or vomiting
  • Muscle pain and backache
  • Eyes being sensitive to light
  • Loss of appetite and feeling generally unwell

The majority of people who contract yellow fever make a full recovery after three or four days. More serious symptoms include:-

  • Yellowing of the skin and eyes (jaundice)
  • Bleeding from the mouth, nose, eyes or ears
  • Vomiting blood or blood in stools

When symptoms reach this more serious stage, consequences can be fatal so seek medical attention immediately.


There is no cure for yellow fever. For mild symptoms painkillers such as paracetamol or ibuprofen can help lower your temperature and relieve aches or pains. Drinking plenty of fluids can help avoid dehydration. Most people make a full recovery after 3 or 4 days. However, up to half of those who have the more serious symptoms of yellow fever will die. If you have serious symptoms, you should seek urgent medical attention.

When you are travelling to countries in Africa, Central America, South America and The Caribbean, it is vital to have a Yellow Fever vaccination so you do not contract Yellow Fever. 

In most cases adults and children recover from contracting Yellow Fever.  However, in some cases contracting Yellow Fever results in serious health implications for adults and in some cases it is a fatal infection
