In the months since its release in the UK, we have seen a huge demand for the new Dengue vaccine, Qdenga.
For those with experience of the disease, the news of its licensing has been much anticipated and we are proud to be one of the first clinics in the UK to offer the vaccine.
What is Dengue Fever?
Dengue is a viral infection that is spread through the bite of an infected aedes mosquito, a species easily recognisable by its striped legs. It occurs in over 120 countries worldwide, mainly in the tropics and sub-tropics, and is the second most common cause of fever in the returning traveller.
The most seriously impacted regions are the Americas, South-East Asia, and Western Pacific, with Asia accounting for around 70% of the world’s disease burden.
It is also spreading to new areas, including Europe, where outbreaks have been increasing in recent years. Read more about this in our recent blog, Dengue Fever in Europe: Temperature Risk.
Since it is transmitted from person to person, via the mosquito vector, it is of particular concern in populated, urban areas.
What are the symptoms of Dengue Fever?
Whilst most cases are asymptomatic, some will develop a severe flu like illness that can require hospitalisation. In rare cases, this will be life threatening.
Common symptoms include;
a high fever,
pain behind the eyes,
vomiting and rash.
There are four serotypes of Dengue virus; for those infected by one type, a subsequent infection is more likely to be life threatening. The severe type of Dengue usually starts a few days after the initial symptoms began. After feeling a bit better, symptoms suddenly return and can include severe abdominal pain, persistent vomiting and bleeding.
Approximately 1 in 20 patients with Dengue will progress into the severe form of the disease.
Dengue Fever Vaccination
Historically, the only protection we could provide was advice surrounding mosquito bite avoidance. With the arrival of Qdenga, we now have the option of a vaccination which provides safe and effective protection.
Studies have shown Qdenga to offer 80% protection from the first dose, with long term immunity achieved after the second.
Who should get vaccinated?
Qdenga can be safely given to those who have previously had the disease, and it is especially important for this group. We would also encourage frequent or long stay travellers to consider the vaccine. The vaccine is licensed for the prevention of Dengue in individuals from 4 years of age and requires two doses, to be given three months apart.
It is a live vaccine, so it’s not suitable for everyone. To discuss your suitability with one of our specialist travel nurses, please book a travel consultation online, or call our reception team on +44 20 7353 5678.
We can usually accommodate same day bookings and suitable vaccinations can be given within the same appointment.

UPDATED RECOMMENDATIONS FOR Yellow Fever VACCINATION: Nigeria
The World Health Organization recently updated the yellow fever recommendations and requirements for residents and travellers to Nigeria.
As of 1 July 2019, the yellow fever certificate requirement for travellers to Nigeria changed. All travellers aged 9 months or over are now required to travel with a yellow fever vaccination certificate along with a valid visa. Failure to provide a valid certificate where required could deny entry to that country, or result in quarantine.
Previously a certificate was only required for those arriving from risk areas countries. However, an on-going outbreak of yellow fever, which started in September 2017, is continuing therefore a revised classification has been made. Between January and April 2019, a total of 930 suspected cases were reported in 447 Local Government Areas.
Advice for travellers
The Fleet Street Clinic would like to remind all travellers from the United Kingdom that there is a risk of yellow fever transmission throughout Nigeria.
We are a Certified Yellow Fever Centre with availability throughout the week and are usually able to accommodate same day appointments requests.
What is Yellow Fever?
Yellow Fever is an acute viral haemorrhagic disease transmitted by infected mosquitoes and has the potential to spread rapidly and cause serious public health impact. There is no specific treatment, although the disease is preventable using a single dose of yellow fever vaccine, which provides immunity for life.

Anyone travelling to Nigeria should book a Pre-Travel Consultation. One of our specialist Travel Nurses will access if a Yellow Fever vaccine is suitable for you.
World Health Organization
The risk of rabies is still widely unknown to the general public.
If caught and symptoms develop, rabies is almost invariably fatal.
Rabies is spread through the saliva of an infected animal and is present in over 150 countries worldwide. Up to 100 children die each day from rabies, and more than 55,000 people a year are killed from the disease, mainly in Asia and Africa.
If bitten or scratched by an infected animal you need to act quickly. Even with pre-travel vaccinations, a course of post-exposure vaccinations are required to prevent disease. If you haven’t had pre-travel vaccinations, the treatment is much more intense. If treatment is given correctly and promptly after exposure, then rabies can be cured but once symptoms develop, it is too late.
Some countries are deemed high-risk of rabies.
Considering this, it’s alarming when we experience resistance from travellers who feel this vaccination isn’t necessary for travel, especially if they are visiting a high risk location.
We feel so passionately that if you are travelling somewhere with a known risks of rabies it only seems sensible to protect yourself against it. Rabies is a vaccine-preventable disease, so make sure you get vaccinated before you travel.
