Will Dengvaxia and the Qdenga vaccine contraindicate each other?

Hi Dr, I am a 34 years old male. I travel a lot and my parents are worried about me getting infected. One of them is dengue. I took my Dengvaxia shot years ago and recently I’ve heard about Qdenga. My question is, if I were to take a Qdenga shot, would Dengvaxia and Qdenga contraindicate each other?

Greetings and thank you for your question.

There isn’t extensive data available specifically on the potential interaction between Dengvaxia and Qdenga vaccines, as they are both relatively new vaccines. Dengvaxia is a vaccine developed by Sanofi Pasteur to prevent dengue fever, while Qdenga is a newer vaccine developed by Takeda for the same purpose.

Given that both vaccines target the same disease, it’s theoretically possible that there could be an interaction or interference between them. However, to determine this definitively, comprehensive studies would need to be conducted specifically examining potential interactions between the two vaccines.

If you’re considering receiving both vaccines, it’s crucial to consult with a healthcare professional who can provide personalized advice based on your medical history, current health status, and the latest available information on vaccine interactions. Always follow the guidance of healthcare experts when making decisions about vaccination.
