What this study is about
In the sponsor’s own words, from the registry.
Background:
\- The National Institute of Allergy and Infectious Diseases (NIAID) at the National Institutes of Health needs healthy volunteers for vaccine clinical trials. This is a screening study that is used to identify healthy volunteers who may be eligible to participate in other clinical trials at the Vaccine Research Center that evaluate investigational vaccines, monoclonal antibodies, and injection devices. The VRC conducts studies that will allow researchers to better understand the immune system and how vaccines and monoclonal antibodies work.
Objectives:
\- To screen healthy volunteers for clinical trials at the NIAID VRC.
Eligibility:
\- Healthy people between 18 and 60 years of age. They must be available to take part in clinical trials and be able to provide blood for research studies.
Design:
* Screening for healthy volunteers to participate in clinical trials is an ongoing process. * Volunteers will be asked about their medical history, including sexual activity and drug use, and a detailed physical exam will be performed. * Blood and urine samples may be collected, and possibly other tests as needed to evaluate the volunteer's health status. * Volunteers will not receive any investigational product in this screening protocol.
