Dengue vaccination before travel
Dengue is becoming a more common reason for travel clinic appointments, especially for people visiting parts of Asia, Latin America and the Caribbean. At Preston Clinic in Preston, we assess whether the dengue vaccine is appropriate for your trip, your previous dengue history and your medical background. It is not a routine jab for every traveller. This page explains who may be considered for it, how the course works, and where dengue risk tends to matter most.
A mosquito-borne virus that often bites in daylight
Dengue is a viral infection spread mainly by Aedes mosquitoes. Unlike the mosquitoes people often associate with malaria, these mosquitoes commonly bite during the day, with activity often around the early morning and early evening. They breed in small collections of water around homes, hotels, building sites and urban areas. Many people with dengue have no symptoms. Others become suddenly unwell, usually after about five to eight days, with a high fever, severe headache, pain behind the eyes, aching muscles and joints, nausea, vomiting or a rash. Most cases settle with careful fluids and symptom control, but a small number develop severe dengue, with bleeding, abdominal pain, organ problems or shock. Previous dengue infection matters. A later infection with a different dengue virus type can carry a higher risk of severe illness. That is one reason the vaccine discussion is more detailed than with many standard travel vaccinations.
Who Qdenga may be considered for
The dengue vaccine currently used in the UK is Qdenga. It is a live, weakened vaccine licensed for dengue prevention in people from 4 years of age. UK guidance says it can be considered for travellers aged 4 and over who have had dengue before and are going to an area with dengue risk or an ongoing outbreak. Exceptionally, vaccination may be considered for someone without known previous dengue, but that needs a careful risk assessment and may require specialist advice. Blood tests looking for past dengue infection can be useful, though they are not perfect, so clinical history and likely previous exposure still matter. The course is two doses, given three months apart, usually by injection into the upper arm. Start early if your dates are fixed. A rushed appointment a fortnight before departure may not leave enough time to complete the course. Qdenga is not suitable for everyone, including people who are immunosuppressed, pregnant or breastfeeding. Common side effects can include a sore arm, headache, tiredness, muscle aches or fever. Booster timing is not firmly established, so future trips should be reassessed rather than assumed covered indefinitely.
Countries where dengue risk is usually part of the conversation
Dengue occurs across tropical and subtropical parts of the world, especially in urban and semi-urban areas. Travellers often ask about it before trips to Thailand, Vietnam, Indonesia, India, Sri Lanka, the Philippines, Brazil, Mexico, Peru and the Caribbean. Risk also exists in parts of Africa and the Pacific, though reporting can be uneven. Season, rainfall, outbreaks and the type of accommodation all influence exposure. A two-week city and beach trip in Thailand is not the same as six months living in a dengue-endemic neighbourhood, but both can involve mosquito bites. The vaccine is generally considered only for countries where dengue risk is established, not for places with occasional isolated reports.
Plan the course while there is still time
If dengue vaccination may be relevant to your itinerary, book early enough to discuss it properly and complete the two-dose course if it is advised. Preston Clinic sees travellers from Preston and nearby areas such as Blackburn and Blackpool for dengue vaccine assessments, travel vaccinations and practical bite-avoidance advice. You can book online or call 01772491185 to arrange an appointment.
Frequently asked
How far before travel should I book a dengue vaccine appointment?
Book at least three months before travel if you can, because the dengue vaccine course is two doses given three months apart. If you are travelling sooner, an appointment can still be useful, but you may not be able to complete the full course before departure.
Can I have the dengue vaccine if I have never had dengue before?
UK guidance mainly considers Qdenga for people who have had dengue in the past and are travelling to a risk area. In exceptional cases it may be considered without known previous infection, but that needs a careful discussion of the benefits, uncertainties and possible risks.
Is Qdenga safe for pregnant women or people with weak immune systems?
Qdenga is a live vaccine, so it is not suitable for people who are pregnant, breastfeeding or immunosuppressed. If any of these apply to you, the appointment should focus on bite prevention and wider travel health planning rather than vaccination.
Do I need the dengue vaccine for Thailand, Bali or Brazil?
Dengue is reported in all three, but vaccination is not automatic. Your previous dengue history, length of stay, exact locations, season, accommodation and medical background all affect the decision. Bring your itinerary to the appointment if you have one.
Does the dengue vaccine mean I can relax about mosquito bites?
No. The vaccine does not remove all dengue risk and it does not protect against other mosquito-borne infections such as chikungunya, Zika or malaria. Use repellent, cover exposed skin where practical, and take extra care around dawn and early evening.
