Longitudinal Humoral and Cell-Mediated Immune Responses in a Population-Based Cohort in Zurich, Switzerland between March and June 2022 - Evidence for Protection against Omicron SARS-CoV-2 Infection by Neutralizing Antibodies and Spike-specific T cell responses
Abstract:Background: The correlate(s) of protection against SARS-CoV-2 remain incompletely de-fined. Additional information regarding the combinations of antibody and T cell-mediated immunity which can protect against (re)infection are needed. Methods: We conducted a population-based, longitudinal cohort study including 1044 individuals of varying SARS-CoV-2 vaccination and infection statuses. We assessed Spike (S)- and Nucleocapsid (N)-IgG and wildtype, delta, and omicron neutralizing antibodies. In a subset of 328 in… Show more
