Qdenga — dengue vaccine
A vaccine against all four dengue serotypes. It was authorised for use throughout the European Union on 5 December 2022; according to the EMA, it is given in two doses to adults, adolescents and children from the age of four. In a study of 20,000 children it cut cases of fever from confirmed dengue by 80% and hospital admissions by 90%.
Where you come across it. A travel health appointment before a trip to a country where dengue is endemic.
The official description of Qdenga does not say it is only for people who have already had dengue: the EMA mentions only age. The DGS page on dengue still says there is no vaccine, but that page is out of date.
