Dengue Fever Vaccine in Edinburgh
If you are travelling to a country where dengue is present, a travel health consultation can help you understand your risk and whether vaccination may be appropriate. At Edinburgh Vaccination Clinic, we offer expert travel health advice and assess suitability for the dengue vaccine as part of a personalised pre-travel appointment.
Dengue is a mosquito-borne viral infection found in many parts of Asia, Latin America, the Caribbean, Africa, and the Pacific. Most infections are mild or even symptom-free, but some people become significantly unwell, and a second dengue infection can carry a higher risk of severe illness.
For travellers visiting areas with dengue risk, vaccination is not the only protection. Careful mosquito bite avoidance is essential and should always be discussed alongside vaccine suitability, itinerary, season, trip duration, and previous travel history.
What is dengue fever?
Dengue is caused by a virus spread by infected Aedes mosquitoes, which usually bite during the daytime. It is common in many tropical and subtropical destinations and can affect both tourists and people visiting friends and relatives.
There are four dengue virus types. Infection with one type does not give full protection against the others, which is one reason repeat infection can sometimes be more serious.
What are the symptoms of dengue?
Symptoms usually begin around 4 to 10 days after a bite from an infected mosquito. Dengue can cause:
- high fever
- severe headache
- pain behind the eyes
- muscle and joint pain
- tiredness and weakness
- nausea or vomiting
- rash
- mild bleeding, such as nosebleeds or easy bruising
Many people recover within 1 to 2 weeks, but occasionally dengue can become severe and require urgent medical care.
Who may benefit from dengue vaccination?
In the UK, Qdenga® can be considered for certain travellers aged 4 years and over who have had dengue infection in the past and are travelling to an area where there is a risk of dengue or an ongoing outbreak. It may also be considered for some people exposed to dengue through their work, such as laboratory staff. In some exceptional situations, vaccination may be considered for someone without known previous dengue, but this requires careful expert assessment.
This means the dengue vaccine is not a routine travel vaccine for everyone going to a tropical destination. Suitability depends on your medical history, previous exposure, destination, and overall risk profile.
About the dengue vaccine
The dengue vaccine currently licensed in the UK is Qdenga®. It is designed to help reduce the risk of dengue disease in suitable individuals. According to UK guidance, the course is:
- 2 doses
- given 3 months apart
- with protection beginning around 14 days after the first dose
Because timing matters, it is best to arrange your travel consultation as early as possible, ideally 4 to 6 weeks before travel, and earlier still if you think you may need a multi-dose vaccine course. Even if you are travelling soon, a last-minute appointment can still be worthwhile.
How is dengue spread?
Dengue spreads through the bite of an infected Aedes mosquito. These mosquitoes are usually most active in the daytime, so bite prevention should not be limited to evenings only.
To reduce your risk of dengue while abroad:
- use an effective insect repellent
- wear clothing that covers the arms and legs where practical
- use screened or air-conditioned accommodation where possible
- take extra care during daytime mosquito exposure
Mosquito bite prevention remains essential even if you receive the vaccine.

- feeling generally unwell for a short period
You will be given appropriate advice at your appointment about what to expect and when to seek further help.
Frequently asked questions
Is the dengue vaccine recommended for all travellers?
No. In the UK, dengue vaccination is not routinely recommended for every traveller. It is usually considered mainly for people aged 4 and over who have had dengue before and are travelling to an area where dengue risk is present.
How many doses do I need?
The UK-licensed dengue vaccine course is 2 doses given 3 months apart.
Can I have the vaccine if I have never had dengue?
Possibly in limited circumstances, but this is not routine and requires careful individual assessment.
Is mosquito repellent still necessary if I am vaccinated?
Yes. Mosquito bite avoidance is important for all travellers, whether vaccinated or not.
When should I book my appointment?
Ideally 4 to 6 weeks before travel, and earlier if a multi-dose schedule may be needed. Even if you are travelling sooner, it is still worth arranging an appointment.
