Abstract

To understand reinfection rates and correlates of protection for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), we established eight different longitudinal cohorts in 2020 under the umbrella of the PARIS (Protection Associated with Rapid Immunity to SARS-CoV-2)/SPARTA (SARS SeroPrevalence And Respiratory Tract Assessment) studies. Here, we describe the PARIS/SPARTA cohorts, the harmonized assays and analysis that are performed across the cohorts, as well as case definitions for SARS-CoV-2 infection and reinfection that have been established by the team of PARIS/SPARTA investigators. IMPORTANCE Determining reinfection rates and correlates of protection against SARS-CoV-2 infection induced by both natural infection and vaccination is of high significance for the prevention and control of coronavirus disease 2019 (COVID-19). Furthermore, understanding reinfections or infection after vaccination and the role immune escape plays in these scenarios will inform the need for updates of the current SARS-CoV-2 vaccines and help update guidelines suitable for the postpandemic world.

Keywords: COVID-19; SARS-CoV-2; antibodies; cohort study; reinfection.

Conflict of interest statement

The authors declare a conflict of interest. The Icahn School of Medicine at Mount Sinai has filed patent applications relating to SARS-CoV-2 serological assays (inventors named FK, VS) and NDV-based SARS-CoV-2 vaccines (inventor named FK). FK would also like to note the following, which could be perceived as a conflict of interest: He has previously published work on influenza virus vaccines with S. Gilbert (University of Oxford), has consulted for Curevac, Merck and Pfizer (before 2020), is currently consulting for Pfizer, Seqirus, Third Rock Ventures and Avimex, his laboratory is collaborating with Pfizer on animal models of SARS-CoV-2, his laboratory is collaborating with N. Pardi at the University of Pennsylvania on mRNA vaccines against SARS-CoV-2, his laboratory was working in the past with GlaxoSmithKline on the development of influenza virus vaccines and two of his mentees have recently joined Moderna. RK reports consulting fees, honoraria, travel funding, and research support from Illumina, QIAGEN, and Perkin Elmer which manufactures SARS-CoV-2 testing and sequencing kits.
