View original scientific description
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.
Primary outcome measures
To screen subjects for their eligibility to participate in clinical trials.
Time frame: Ongoing
Duration of subject participation is variable, and may last from a few weeks to several months for each subject.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
