Hello and thank you for your question.

The Dengue Vaccine (Qdenga) works well, with a success rate of up to 86.4% according to a study. This means it helps prevent dengue fever in a lot of people who get it. However, The duration of protection provided by Qdenga Dengue Vaccine is still being studied. Clinical trials have shown that the vaccine provides protection for several years, but how well it works can depend on things like your age, if you’ve had dengue before, and what kinds of dengue virus are around where you live. Long term efficacy is still being studied.

If you have further questions about dengue fever or the vaccine, I recommend consulting with a healthcare professional for personalised advice and guidance.
