Investigating how the dengue vaccine works in people with prior dengue infection

Immunogenicity of the dengue vaccine CYD-TDV in a dengue virus serotype 1 immune population

NIH-funded research Oregon Health & Science University · NIH-10892299

This study is looking at how the dengue vaccine works better for people who have had dengue before, and it aims to find out why that is, so we can make the vaccine even more effective for everyone.

What this research studies

This research focuses on understanding the immune response generated by the dengue vaccine CYD-TDV in individuals who have previously been infected with the dengue virus. The study aims to explore why the vaccine is more effective in these individuals compared to those without prior infection. By examining the role of immune cells and antibodies, researchers hope to uncover mechanisms that enhance the vaccine's effectiveness. This could lead to improved vaccination strategies for dengue prevention.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals aged 9-16 years who have a confirmed history of dengue virus infection.

Not a fit: Patients who have never been infected with the dengue virus may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to more effective dengue vaccination strategies, potentially reducing the incidence of dengue fever.

How similar studies have performed: Previous research has shown that understanding immune responses to vaccines can lead to significant advancements in vaccine efficacy, suggesting potential for success in this area.
