TGen seeks volunteer patients for COVID-19 immunity study

A few drops of blood could reveal insights into how antibodies could stop this pandemic

The Translational Genomics Research Institute (TGen), an affiliate of City of Hope, is looking for volunteers: individuals who have run the course of COVID-19, and whose immune system may have built up antibodies against this still mysterious disease.

Participants in The COVID Immunity Study must be U.S. residents, age 18 or older, have tested positive for COVID-19, and then recovered. They may sign up at:

This is a research study, and will not be used to diagnose disease among the participants. However, this study could eventually lead to new methods of diagnosing COVID-19, and help in the development of antibody therapies, and perhaps vaccines.

“We are using cutting-edge research tools to study, in depth, the immune response to COVID-19,” said Dr. John Altin, an Assistant Professor in TGen’s Pathogen and Microbiome Division, the institute’s infectious-disease branch in Flagstaff, also known as TGen North. “Our goal is to enable urgently-needed new diagnostics and treatments for this virus.”

Dr. David Engelthaler, Director of TGen North and Arizona’s former State Epidemiologist, said this “citizen-science” study could help researchers better understand how the virus has moved through our community.

“This will help us learn more about how, when and why we produce antibodies in response to a COVID-19 infection. One class of antibodies tackles the infection first, and then another comes in to finish the job,” Dr. Engelthaler said. “Knowing when these different immune responses occur, and how long they last, could help us understand if some patients gain a certain degree of immunity against reinfection. We need to know how that works.”

Dr. John Zaia, Director of the Center for Gene Therapy at City of Hope, is working on this study with TGen.

“Antibody testing will be critical very soon as we emerge from the COVID-19 pandemic, so this project is immensely important,” Zaia said. “To supplement this study, I am leading a research project at City of Hope, in collaboration with Dr. Altin’s lab, that will hopefully result in the development a COVID-19 virus antibody neutralization test. Together, these two tests will help us understand what is necessary for immune protection against COVID-19.”

Those who sign up for TGen’s study will be asked to complete a short online health questionnaire. TGen would then mail them a simple blood-spot collection kit. They would be instructed to prick the end of a finger and put a drop of blood on a sample collection card. A week later, they would put another drop of blood on the sample collection card, and then mail the test back to TGen.

TGen is hoping to initially recruit a few hundred volunteers to further understand the biological response to the SARS-CoV-2 virus, which causes the COVID-19 disease.
