Planning a family trip to Africa or South America? One of the first things you need to check is whether your children need the yellow fever vaccine. It is a question that comes up often, and the answer depends on your child’s age, destination, and health history.
This guide walks you through everything parents need to know, from who can get vaccinated to which countries require proof of immunisation at the border.
What Is Yellow Fever and Why Does It Matter for Families?
Yellow fever is a viral disease spread by infected mosquitoes, mainly in tropical and subtropical areas of Africa and South America. The name comes from the jaundice (yellowing of the skin) that can develop in severe cases.
Symptoms range from mild, including fever, headache, and nausea, to life-threatening organ failure. There is no specific treatment once symptoms develop, which is why the yellow fever vaccine is so critical for travellers heading to affected regions.
For children, the risks are the same as for adults. A mosquito bite in a high-risk area can cause serious illness regardless of age. Vaccination is the most reliable protection available.
Is the Yellow Fever Vaccine Safe for Children?
Yes, the yellow fever vaccine is safe for most children, but age matters significantly.
Children aged 9 months and older
The vaccine is recommended and routinely given to children from 9 months of age who are travelling to or living in yellow fever risk areas. One dose provides lifelong protection in the vast majority of cases.
Children aged 6 to 9 months
Vaccination is only considered if the travel risk is very high and unavoidable. The decision should always be made in consultation with a travel health professional, as the risk of a rare side effect called vaccine-associated neurological disease is higher in this age group.
Children under 6 months
The yellow fever vaccine must not be given to children under 6 months of age. This is a firm medical contraindication. If travel to a yellow fever zone cannot be avoided, parents should seek specialist advice and take strict mosquito avoidance precautions throughout the trip.
Which Countries Require the Yellow Fever Vaccine for Children?
Some countries require proof of yellow fever vaccination as a condition of entry, regardless of where you are travelling from. This applies to children as well as adults. An International Certificate of Vaccination or Prophylaxis (ICVP) is the official document required at the border.
| Region | Countries with Entry Requirements | Minimum Age for Certificate |
| Africa | Ghana, Kenya, DR Congo, Uganda, and others | Usually 9 months, varies by country |
| South America | Brazil (certain regions), Bolivia, Ecuador, Peru | Usually 9 months, varies by country |
| Asia / Pacific | Some countries require proof if arriving from endemic areas | Varies by country |
Requirements change regularly. Always check the entry rules for each country on your itinerary before you travel, particularly if you have a connecting flight through an endemic region.
How Many Doses Does a Child Need?
A single dose of the yellow fever vaccine provides lifelong immunity for most people, including children. Historically, booster doses were recommended every 10 years, but the World Health Organization updated its guidance in 2013 to confirm that one dose is sufficient for long-term protection.
There are some exceptions where a booster may be recommended:
- Children vaccinated before their first birthday may need a repeat dose after turning 1
- People who received a blood transfusion around the time of vaccination
- Pregnant women who were vaccinated during pregnancy
- People with weakened immune systems
A travel health clinician at Chertsey Pharmacy can advise on whether your child needs a fresh dose based on their vaccination history.
Are There Any Side Effects Parents Should Know About?
Most children tolerate the yellow fever vaccine well. Common side effects are mild and short-lived:
- Soreness or redness at the injection site
- Low-grade fever for a day or two
- Headache or mild muscle aches
- Fatigue
These typically resolve within a few days. Serious adverse reactions are rare. The two most significant are:
Vaccine-associated neurotropic disease (YEL-AND)
This affects the nervous system and is most common in infants under 6 months, which is why the vaccine is not given to this age group. It is extremely rare in children over 9 months.
Vaccine-associated viscerotropic disease (YEL-AVD)
This is a severe systemic reaction that mimics yellow fever itself. It is very rare, estimated at fewer than 1 in 250,000 doses, but can be serious. It is more common in older adults and those with thymus disorders.
The risk of these side effects must always be weighed against the risk of contracting yellow fever in a high-risk area, where the disease has a fatality rate of up to 50% in severe cases.
Who Should Not Get the Yellow Fever Vaccine?
There are situations where the vaccine is not suitable for a child. You should discuss your child’s full health history with a clinician before vaccination if they:
- Are under 6 months old
- Have a known egg allergy (the vaccine is produced in eggs)
- Have a thymus disorder or have had their thymus removed
- Have a weakened immune system due to illness or medication
- Are undergoing chemotherapy or radiotherapy
- Have a severe allergy to any component of the vaccine
If your child falls into any of these categories, Chertsey Pharmacy can provide an exemption letter and advise on mosquito bite prevention strategies to reduce risk during travel.
How to Get the Yellow Fever Vaccine for Your Child in the UK
In the UK, the yellow fever vaccine is only available at registered yellow fever vaccination centres. It cannot be administered at a standard GP surgery.
Here is what to expect when you book:
- Travel health consultation: A clinician reviews your itinerary, your child’s age and health, and recommends the appropriate vaccines.
- Vaccination: The yellow fever vaccine is given as a single injection, usually in the upper arm.
- ICVP certificate: You receive an International Certificate of Vaccination or Prophylaxis, which becomes valid 10 days after vaccination and is valid for life.
Chertsey Pharmacy is a registered yellow fever vaccination centre. You can book a travel health appointment for your child and receive the vaccine and certificate in one visit.
Yellow Fever Vaccine and Other Travel Vaccines for Children
Yellow fever is rarely the only vaccine needed for tropical travel. Depending on your destination, your child may also need:
- Hepatitis A
- Typhoid
- Malaria prevention medication (antimalarials)
- Rabies (for longer stays or areas with limited medical access)
- Meningitis ACWY
- Japanese Encephalitis (for parts of Asia)
A travel health consultation helps you plan the full picture rather than just a single vaccine. Our team at Chertsey Pharmacy reviews your complete itinerary and recommends a tailored vaccination schedule for each family member.
Mosquito Bite Prevention: Essential Alongside Vaccination
The yellow fever vaccine is highly effective, but it works best alongside practical mosquito bite prevention, especially for young children and infants who cannot be vaccinated.
- Use DEET-based repellent (20 to 50% DEET is safe for children over 2 months)
- Dress children in long sleeves and trousers after dusk
- Use insecticide-treated bed nets
- Stay in air-conditioned or well-screened accommodation where possible
- Avoid outdoor activities at dawn and dusk when mosquitoes are most active

Frequently Asked Questions
At what age can a child get the yellow fever vaccine?
Children can receive the yellow fever vaccine from 9 months of age for routine travel to high-risk areas. In exceptional circumstances it may be given from 6 months under specialist guidance. It must not be given to infants under 6 months.
Does my child need the yellow fever vaccine for travel to Kenya?
Yes. Kenya requires proof of yellow fever vaccination for all travellers aged 1 year and older arriving from or transiting through yellow fever endemic countries. A valid ICVP certificate is required at the border. Always check the most current entry requirements before travel as these can change.
How long does the yellow fever vaccine last for children?
One dose provides lifelong protection for most children. Children vaccinated before their first birthday may be advised to have a repeat dose after turning 1, as immunity may be less reliable when the vaccine is given in early infancy.
Can a breastfeeding mother pass yellow fever vaccine protection to her baby?
Breastfeeding transfers some antibodies but does not provide reliable or sufficient protection against yellow fever. If a breastfed infant will be travelling to a high-risk area, seek specialist advice on the best approach given the infant’s age and risk level.
Where can I get the yellow fever vaccine for my child near Chertsey?
Chertsey Pharmacy is a registered yellow fever vaccination centre. You can book a travel health consultation for your child, receive the vaccine, and collect your ICVP certificate in a single appointment.
