More Evidence of Protective Immunity After COVID-19

摘要

During a COVID-19 outbreak on a fishing vessel, individuals with neutralizing anti-SARS-CoV-2 antibodies prior to exposure did not get infected. Most COVID-19 patients develop neutralizing antibodies against SARS-CoV-2. Whether such antibodies make them immune to SARS-CoV-2 infection is unclear, especially after reports of patients who appeared to have contracted SARS-CoV-2 twice within a few weeks. Now, an observational study of a COVID-19 outbreak on a fishing vessel with 122 crew members (113 men and 9 women) sheds some light on this issue.
