Is Qdenga Dengue Vaccine effective against all serotypes of the dengue virus?

Does the Qdenga Dengue Vaccine effectively protect against all serotypes of the dengue virus, or are there limitations to its efficacy based on factors like age, prior exposure, or other considerations?

Hello and thank you for your question.

The Qdenga vaccine is designed to protect against the four serotypes of the dengue virus (DEN-1, DEN-2, DEN-3, and DEN-4), which are the main types known to cause dengue fever.

Additionally, the efficacy of the vaccine can vary based on factors such as the age of the individual receiving it and their prior exposure to dengue. It’s always best to consult with a healthcare professional for specific recommendations regarding vaccination and protection against dengue fever.

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