What this trial studies

This study enrolls healthy volunteers to collect serum and RNA samples and gather clinical and laboratory data to determine eligibility for future clinical studies on infectious diseases like Zika and influenza. It includes influenza challenge studies, where participants are exposed to the flu virus to study the body's response and improve prevention and treatment methods. The goal is to enhance understanding of viral infections and assist in vaccine development. Up to 5000 participants will be recruited at the NIH Clinical Center.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18 to 65 with no significant health abnormalities.

Not a fit: Patients with significant health issues or those outside the age range may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better prevention and treatment strategies for influenza and other viral infections.

How similar studies have performed: Previous human challenge studies have provided valuable insights, but this approach is expanding to include emerging infectious diseases, making it a novel effort.

EXCLUSION CRITERIA:

1. Self-reported history of any significant medical condition including but not limited to:

   * Chronic pulmonary disease (such as asthma, emphysema)
   * Chronic cardiovascular disease (cardiomyopathy, congestive heart failure, cardiac surgery, ischemic heart disease, known anatomic defects)
