Is there a vaccine available for travellers against dengue?

While dengue vaccines such as Qdenga exist, they are mostly suggested for travellers who have previously had a laboratory-confirmed dengue infection and who are going to endemic areas.

For travellers who have never had dengue, meaning dengue-naïve individuals, receiving some older dengue vaccines (like Dengvaxia) can paradoxically raise the chance of developing severe dengue later, after a future infection. Newer vaccines have approval requirements that depend on your home country’s regulatory bodies, for example, the FDA or the EMA. Always talk with a specialised travel medicine physician well in advance of your trip, so they can decide whether vaccination is safe and suitable for your medical background.
