Volunteer for COVID-19 Clinical Trials

NIAID is conducting and supporting clinical trials evaluating therapies and vaccine candidates against severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19), as well as studies of people who have recovered from infection.

Featured COVID-19 Studies

Ongoing NIAID-supported COVID-19 Studies

Below is a selection of ongoing NIAID-supported studies. A frequently updated, comprehensive list of all COVID-19 clinical trials can be found on ClinicalTrials.gov.

Select from the options below based on which health category you fall under to find COVID-19 clinical study volunteer opportunities appropriate for you.

To qualify, volunteers must not have had a positive COVID-19 diagnostic test at any time in the past, even if you did not have any symptoms. If you have had a positive COVID-19 test in the past, you may qualify for studies that are seeking volunteers who have recovered from COVID-19.

These studies are seeking volunteers who may be exposed to SARS-CoV-2, the virus that causes COVID-19, in their everyday activities:

AstraZeneca Study of COVID-19 Vaccine Candidate AZD1222

  • Study Goal: The trial primarily is designed to determine if the vaccine candidate, AZD1222, can prevent symptomatic COVID-19 after two doses. 
  • Locations: Clinical research sites are distributed throughout the United States. Fill out the volunteer questionnaire to find out if you qualify and you will be matched with the appropriate research site.
  • Official Study Title: Phase III Double-blind, Placebo-controlled Study of AZD1222 for the Prevention of COVID-19 in Adults

Pandemic Blood Sampling Study

  • Study Goal: A study at the NIH Clinical Center in Bethesda, Maryland, aims to determine how many adults in the United States without a confirmed history of infection with SARS-CoV-2, the virus that causes COVID-19, have antibodies to the virus. The presence of antibodies in the blood indicates a prior infection. In this “serosurvey,” researchers will collect and analyze blood samples from as many as 10,000 volunteers to provide critical data for epidemiological models that look into how an illness spreads in the community. The results will help shed light on the extent to which the virus has spread undetected in the United States and provide insights into which communities and populations are most affected.
  • Locations: Samples can be taken in person at the NIH in Bethesda, Maryland, or home sample kits may be mailed if you qualify to volunteer.
  • Official Study Title: SARS-COV2 Pandemic Serosurvey and Blood Sampling

Working or living with others who have COVID-19 puts you at high risk of exposure. If you live with someone who has tested positive for SARS-CoV-2, the virus that causes COVID-19, or you work in a medical or assisted living facility where you are caring for COVID-19 patients, you may qualify for these studies.
