1. Yellow fever vaccine Leicester
• Yellow fever is a serious viral infection
that's spread by a type of daytime
biting mosquito known as the Aedes
Aegypti mosquito.
• It can be prevented with a vaccination.
• Yellow fever mainly occurs in sub-
Saharan Africa (countries to the south
of the Sahara desert), South America
and in parts of the Caribbean.
• Since 1996, six travellers from Europe
and North America have died from the
infection. None of them were
vaccinated.

2. • There is a vaccination for yellow fever. Some countries require proof of vaccination
(a certificate) against yellow fever before they let you enter the country.
• You should have a yellow fever vaccination at least 10 days before your travel.
• This will allow enough time for your body to develop protection against the yellow
fever infection.

3. 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.
• People who are allergic to eggs - The vaccine contains small amounts of egg.

4. • 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.
• People who have a condition that affects the thymus gland (part of your immune
system that is located in your upper chest).
• People who are currently very unwell (for example with a high fever) – this is to
avoid confusing the diagnosis of your current illness with any side effects from the
vaccine.
• Elderly yellow fever naïve travellers - Those who have not been previously
exposed to the vaccine who are 60 years of age or over (unless the risk of yellow
fever is unavoidable).

5. Side effects of the vaccine
• After having the yellow fever vaccine, 10-30% of people will have mild side effects
such as:
1- Headache
2 -Muscle pain
3- Soreness at the injection site
4- 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.

6. • 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 nervous system, including the brain and spinal
cord.
• YEL-AND occurs in around four cases out of every 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 by around five times, so in these cases the risk-
benefit needs to be carefully assessed by the doctor or nurse.
