Insights from an observational translational research program during the COVID-19 pandemic: Four years of experience.

The COVID-19 Biorepository at Beth Israel Deaconess Medical Center in Boston was initiated in 2020 to address questions about COVID-19 infection and vaccination in a time of urgent need. From April 2020 through July 2024, we enrolled 1018 participants and collected thousands of biospecimens. We enrolled participants from the general population as well as from specific populations that were not well represented in clinical trials, including immunosuppressed, pregnant, and lactating individuals. Our observational study was designed to accommodate the rapidly changing landscape of the pandemic, including the introduction of new vaccines and boosters, breakthrough infections, and emerging variants. Reflecting on the past four years of this experience, we believe that teamwork, collaboration, and flexibility were key factors for the success of this effort, which generated data in real time about COVID-19 vaccine responses in multiple populations, hybrid immunity following breakthrough infections, immune evasion of emerging variants, and immune imprinting following booster immunizations. Rapid dissemination of data through preprints, peer-reviewed publications, and public communications allowed for the real time use of our findings to address public health issues and to inform vaccine policies. The dedication of the study participants, clinical investigators, and laboratory investigators made this research program possible.
