We made history with safe and effective vaccines and we’ll keep working as long as there are people to protect, variants emerging, and research answers needed to keep us all safe. That means we still need you!
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.

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 the health category you fall under to find COVID-19 clinical study volunteer opportunities.
If you have never had a positive COVID-19 diagnostic test at any time in the past, you may qualify to volunteer for one of these studies. If you have had a positive COVID-19 test in the past—including if you had no symptoms but tested positive—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:
