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. Vaccinatio
n 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.

Certificate of proof of vaccination
Under regulations set out by the World Health
Organization (WHO), anyone traveling to a country
or area where the Aedes aegypti mosquito is found
must have the vaccine or have an International
Certificate of Vaccination or Prophylaxis (ICVP).
You can find a list of all the countries that
require you to have an ICVP in the WHO
International travel and health guide. You can
also search the country information on NaTHNaC to
find out whether the places you are visiting
require an ICVP. If you have been traveling in
an at-risk area during the past month, it is a
good idea to carry your certificate with you.
This will help avoid potential problems with
immigration. It is possible for travelers without
a valid yellow fever vaccination certificate to
be vaccinated and held in isolation for up to 10
days. An ICVP is not required for entry into the
UK.

If you lose your certificate, you may be able to
get another one reissued as long as you have
details of the vaccination batch number and the
date you had the vaccination. Always consult
staff at a designated vaccination centre if you
are planning to travel to an area where there is
a risk of getting yellow fever. If you tell them
where you are traveling to, they will be able to
advise you about whether you need to be
vaccinated against yellow fever and whether you
need an ICVP.

Exemption letters
In cases where having a yellow fever vaccination
is not advised, your GP may be able to issue you
with an exemption letter. The letter should be
written on headed notepaper and include the
practice details. It may be accepted by some
immigration authorities although this is not
guaranteed. If you are traveling from an area
where there is a risk of yellow fever without a
valid yellow fever certificate, immigration
officials are legally entitled to quarantine you
for a period of at least seven days at the point
of arrival into a country.

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) 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. 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.
