Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Transmission Dynamics and Immune Responses in a Household of Vaccinated Persons

Clin Infect Dis. 2022 Aug 24;75(1):e303-e306. doi: 10.1093/cid/ciac029.

Abstract

While SARS-CoV-2 vaccines prevent severe disease effectively, postvaccination "breakthrough" COVID-19 infections and transmission among vaccinated individuals remain ongoing concerns. We present an in-depth characterization of transmission and immunity among vaccinated individuals in a household, revealing complex dynamics and unappreciated comorbidities, including autoimmunity to type 1 interferon in the presumptive index case.

Keywords: SARS-CoV-2; anti; antibody neutralization; autoimmunity; breakthrough infection; interferon autoantibody.
