Dengue fever is a mosquito-borne viral infection affecting large parts of South East Asia, Latin America, and sub-Saharan Africa. The Priory Pharmacy in York offers the Qdenga dengue vaccine for eligible individuals who have a confirmed prior history of dengue infection and who are returning to dengue-endemic regions. A detailed pre-vaccination assessment is essential, as this vaccine is not suitable for all travellers.

The Qdenga vaccine is a live attenuated tetravalent dengue vaccine providing protection across multiple dengue serotypes. It is given as a two-dose schedule with three months between doses. Current guidance supports its use in individuals with prior confirmed dengue infection; its use in dengue-naive individuals (those who have never previously been infected) is not recommended, as this may increase the risk of severe dengue upon subsequent natural infection. Our pharmacist will review any documentation of prior dengue infection and conduct a thorough pre-vaccination assessment before proceeding. Dengue prevention also requires robust mosquito avoidance measures, which our team will discuss in detail.

Prior dengue infection is confirmed through serology (blood testing) showing the presence of dengue antibodies. If you have not had formal testing, our pharmacist will discuss whether this should be arranged before proceeding with vaccination.
The Qdenga vaccine is licensed from age 4 upwards in those with prior confirmed dengue infection. Our pharmacist will assess suitability on an individual basis.
In dengue-naive individuals, vaccination may prime the immune system in a way that could increase the risk of more severe dengue upon subsequent natural infection with a different serotype. This is a nuanced immunological issue that our pharmacist can discuss in detail during your consultation.
No. Mosquito bite prevention remains essential regardless of vaccination status. DEET-containing repellents, appropriate clothing, and the use of mosquito nets are important complementary measures.
