How early dengue exposures shape immunity in Thai families

Defining correlates of protection from dengue illness in a long-term cohort study of multigenerational house-holds in Thailand

NIH-funded research Upstate Medical University · NIH-11120938

Researchers are following multigenerational households in Thailand to learn how children’s earliest exposures to dengue and related viruses change their chances of getting sick later.

What this research studies

This project follows a long-term family cohort in Kamphaeng Phet, Thailand, where team members regularly check for new dengue infections and collect blood samples. Children and other household members have antibody tests and clinical monitoring to record who gets sick and how severe illness becomes. The researchers compare immune markers from people with different early exposures to define laboratory signs that link to protection against multiple dengue types. Results will be used to create benchmarks that could help guide vaccine development and better interpret immune tests.

Who could benefit from this research

Good fit: Ideal participants are children and family members living in dengue-endemic areas (especially in or near Kamphaeng Phet, Thailand) who can provide blood samples and be followed over time.

Not a fit: People living outside dengue-endemic regions, those not enrolled in the household cohort, or those seeking immediate treatment for acute dengue are unlikely to directly benefit from this observational research.

Why it matters

Potential benefit: If successful, the work could show which immune responses protect children from severe dengue and help guide safer, more effective vaccines and tests.

How similar studies have performed: Previous long-term dengue cohorts have shown durable multi-type immunity after repeat exposures, but precisely defining lab markers that predict protection across serotypes remains a newer aim.
