How do Dengvaxia and Qdenga dengue vaccine work?

I know that Dengvaxia and Qdenga are dengue vaccines, but do they work differently? Which one should i choose?

Hi, good morning and thank you for your question.

It is important to first note that both Dengvaxia and Qdenga have the same function, which is to prevent the infection of the dengue virus into our bodies. Even so, they can be slightly different in their operation.

What sets Qdenga apart is that it doesn’t require the patient to have a previous history of dengue infection, unlike Dengvaxia. This makes Qdenga a more accessible option for individuals who haven’t been exposed to dengue before and it is also the only vaccine approved in Malaysia.

For any further enquiries or questions about the operations of dengue vaccine, consult a doctor for more information.
