Yellow fever is a viral infection spread by mosquitoes found in parts of Africa and South America. It can be fatal in around 8% of cases. There is an effective vaccination available that provides lifelong protection with a single dose. The yellow fever vaccine is recommended for travel to areas where the disease is endemic or where proof of vaccination is required for entry. It should be received at least 10 days before travel to allow time to develop antibodies.

Yellow Fever Vaccination
Luckily, there is a very effective vaccination for yellow fever. Some countries
require proof of vaccination (a certificate) against yellow fever before they let
you enter the country.
Vaccination is the single most effective way of preventing yellow fever.
In the UK, Stamaril (produced by Sanofi Pasteur MSD) is the only licensed
yellow fever vaccine. A single dose of the yellow fever vaccine will protect
against yellow fever for life. It is no longer recommended to have a booster dose
every 10 years (WHO, World Health Organisation, July 2016).
Ideally, you should have the yellow fever vaccination at least 10 days before
your travel. This will allow enough time for your body to develop protective
antibodies against the yellow fever infection.

The Yellow Fever Vaccination is
Recommended for:
 Anyone traveling to, or living in, areas or countries where yellow fever is
endemic.
 Anyone traveling to a country where an International Certificate of Vaccination
or Prophylaxis (ICVP) against yellow fever is required for entry.
 You must have a yellow fever vaccination at least 10 days before you travel. This
will allow enough time for your body to develop protective antibodies against the
yellow fever infection.

Who should not be Vaccinated?
People who should not have the yellow fever vaccination include:
 Babies under nine months of age – babies who are six to nine months
old should only be vaccinated if the risk of getting yellow fever during
travel is unavoidable.
 Pregnant women – unless the risk of yellow fever is unavoidable.
 Breastfeeding women – unless the risk of yellow fever is unavoidable.
 People whose immune systems are lowered (immunosuppressed) – such
as people with HIV and those receiving chemotherapy or radiotherapy.

6. www.travel-doc.com
 People who are allergic to eggs – the vaccine contains small amounts of egg
white protein, albumin.
 People who have had a severe allergic reaction (anaphylaxis) to a previous
dose of the yellow fever vaccine.
 People who are allergic to any of the ingredients in the vaccine (including
eggs).
 People who have a condition that affects the thymus gland (part of your
immune system that is located in your upper chest).

7. www.travel-doc.com
 People who are currently very unwell (such as with a high fever) – this is
to avoid confusing the diagnosis of your current illness with any side
effects from the vaccine.
 Yellow fever naïve travellers – those who have not been previously
exposed to the vaccine who are 60 years of age or over should be
individually assessed by the travel doctor or nurse.

Side Effects of the Vaccine
After having the yellow fever vaccine, 10-30% of people will have mild side
effects such as: headache, muscle pain, soreness at the injection site and mild
fever.
Reactions at the injection site usually occur one to five days after being
vaccinated, although other side effects may last for up to two weeks.
An allergic reaction to the vaccine occurs in one case out of every 130,000
doses of the vaccine that are given. Yellow fever vaccine-associated
neurological disease (YEL-AND).

9. www.travel-doc.com
Rarely, the yellow fever vaccine is associated with a neurological condition known as
yellow fever vaccine-associated neurological disease (YEL-AND). Neurological
means that it affects the nerves and the nervous system, including the brain and spinal
cord.
YEL-AND occurs in around four cases out of every 1 million doses given. However,
for people who are 60 years of age or over and yellow fever vaccine naïve, the
incidence of YEL-AND increases to around one in every 50,000. This needs to be
balanced against the risk of acquiring the disease.

Preventing Mosquito Bites
As well as getting the yellow fever vaccination before traveling, you should
also take steps to avoid being bitten by mosquitoes.
The mosquitoes that carry yellow fever bite during daylight hours. Although
it may not always be possible, you should try to:
 Avoid places where mosquitoes live, such as swamps, forests and
jungles.
 Choose air-conditioned accommodation. Mosquitoes do not like air-
conditioned spaces.

11. www.travel-doc.com
 Choose accommodation with mesh screening over the windows and
doors.
 Wear loose fitting, long-sleeved tops and trousers, even in the heat of day.
 Use insect repellent containing DEET on exposed skin, such as Jungle
Formula. 50% DEET is sufficient.
 Burn a mosquito coil or use a plug-in device that releases insecticide in
your accommodation.
 Use a mosquito net where possible, especially in bedrooms that are not
air-conditioned.
