Probably not a fit

Patients with medical conditions that impair their ability to provide informed consent or those with bleeding disorders may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to evaluate immune responses in adults aged 18 and older by collecting blood and tissue samples from individuals who have recently been vaccinated or recovered from infections. Participants will undergo clinical evaluations and provide various specimens, including blood and mucosal samples, to help researchers understand the immune correlates of protection. The data collected will enhance knowledge about immune responses and assist in the development of vaccines against infectious diseases. Participation is voluntary, and all procedures are optional.

Why it matters

Potential benefit: If successful, this study could lead to improved vaccine development and better understanding of immune responses to infections.

How similar studies have gone: Other studies have shown success in evaluating immune responses through similar specimen collection methods, indicating a promising approach.
