We began our research in March 2020 with seed funding from the Erika J. Glazer Family Foundation and Cedars-Sinai Medical Center. Working with key partners across institutions, we launched our first antibody study for healthcare workers during the initial lockdown. With the support of additional funding, we were later able to provide additional follow-up for our healthcare employees, and have now expanded enrollment to include patients representing our wider Cedars-Sinai community.

Here are a few milestones reflecting our accomplishments so far: >30K blood draws, >25K health surveys, 56 research papers, >675 media reports on our research findings (including ABC, CBS, CNN, Forbes, NPR, NYTimes, Time, USNews), >350K downloads of our research reports, and positive impact on global public health policy, especially related to vaccines. To view scientific reports of the discoveries made so far, you may click here.

Note that the IgG-Spike antibody levels are in log(10) values to fit to scale. The lines representing average antibody levels over time are not adjusted for factors such as prior infection, timing or doses of vaccines, or medical conditions. There is currently no established “normal” range for antibody levels, in part because antibody levels measured in the blood can vary in relation to many factors. For this reason, we are collecting more data for our research focused on understanding what range of antibody level responses can be expected for different individuals in different situations.
