The Yale LISTEN Study

Thank you for being interested in the Yale LISTEN Study!

LISTEN stands for Listen to Immune, Symptom and Treatment Experiences Now.

The purpose of this study is to understand Long Covid, post-vaccine adverse events and the corresponding immune responses by collecting information about symptoms and medical history from participants who are members of a patient community, and by collecting blood and saliva samples from some participants.

We are recruiting from the Hugo Health Kindred COVID-19 Community, which is an online patient community which enables people to connect with others, gain agency over their health data and consent to have their data be shared with researchers.


If you have any questions regarding the LISTEN Study, please email us at

You Are Eligible to Participate in This Study If You:

  • Are a member of the Hugo Health Kindred COVID-19 Community.
  • Are currently 18 years or older
  • Speak English or Spanish

How the Study Works

People who join the LISTEN study are consenting to have the health data and surveys that they generated on the Kindred community shared with LISTEN researchers. The LISTEN researchers will analyze the data for insights about the health of people in the study, including those with long COVID and those with syndromes after vaccination. We will characterize demographic, clinical, social, and environmental factors associated with health status. We will share some results back with participants, when analysis is completed. We will also treat participants with respect, listen to their suggestions about the study, and engage them in interpreting and disseminating results.

We will invite some participants to give blood and saliva samples as part of this study. A trained phlebotomist from ExamOne (a part of Quest labs) will come to collect the samples at a time that people schedule using the ExamOne online portal. They can come to people’s homes or meet them at a Quest center. We will help people make appointments.

How to Join the Study

The study is recruiting from the Hugo Kindred Community. The reason we did this is because there is an interest in rapid enrollment and this community is oriented toward participating in research. Also, the LISTEN study is largely depending on data collected in Kindred for the study.

Kindred is an app, created by Hugo Health, that allows people to join communities where they can connect to their data, other patients, and research studies. As a Disclosure, one of the leaders of the LISTEN study is a co-founder of Hugo Health. This method of recruitment has been approved by the Yale committee that oversees studies and protects the interests of participants.

You may leave Kindred at any time (although no more data will be sent to the study). Learn more about Hugo Health Kindred.

If I change my mind about the LISTEN study, can I disenroll?

You can disenroll in the LISTEN study at any time and without consequence to you. Disenrolling in the Yale LISTEN Study does not automatically end your participation in Kindred, but it is also possible to delete your Kindred account in the app settings.

The Yale COVID Recovery Research Team Principal Investigators are Akiko Iwasaki, PhD and Harlan Krumholz, MD, SM.
