AACC COVID-19 Immunity Study

Answering the questions of vaccine longevity

The scientific community continues to devote great efforts to understanding all aspects of COVID-19, but a key question that has not yet been answered is how long the currently available SARS-CoV-2 vaccines will protect against the virus.

In order to gain further insight into this important issue, AACC is launching the COVID-19 Immunity Study, which will examine immune responses to SARS-CoV-2 vaccination or prior infection in a large cohort of volunteers who are diverse in areas such as age, sex, race, ethnicity, vaccine regimens, and geography. The study will also further examine the utility of serologic tests as a means to measure lasting immunity.

Participating in the Study

Blood samples for this planned study will be collected September 28-30 at the 2021 AACC Annual Scientific Meeting & Clinical Lab Expo in Atlanta.

We are asking all registered meeting attendees and exhibitors who are 18 years of age and older to consider donating blood for the study to ensure that the research cohort is as diverse as possible and to help find the answers to these essential questions. This approach to sample collection is modeled after AACC’s Universal Sample Bank program, which used samples from attendees of the 2015 AACC Annual Scientific Meeting in support of important research related to troponin.

People who aren’t able to attend the meeting in person will also have the opportunity to contribute to the study by submitting answers to a COVID-19 health questionnaire.

Sign up to get more information on participating. AACC is currently in the process of securing Institutional Review Board approval for the study. Once approval is secured, we will provide more details on next steps to all those who have indicated their interest.

Benefits for Study Participants

In return for donating blood, study participants will receive the results of their individual antibody profile tests after all the collected samples have been analyzed.

Every blood donor will also be entered into a drawing for one of two complimentary registrations to the 2022 AACC Annual Scientific Meeting & Clinical Lab Expo.
