Comparison of Waning Neutralizing Antibody Responses Against the Omicron Variant 6 Months After Natural SARS-CoV-2 Infection (With/Without subsequent COVID-19 Vaccination) Versus 2-dose COVID-19 Vaccination.

ABSTRACT: Following SARS-CoV-2 infection, subsequent ChAdOx1 nCoV-19 induced similar neutralizing antibody levels against the original strain but significantly higher levels against the Omicron variant compared to those who were not vaccinated. Prior SARS-CoV-2 infection exhibited higher neutralization antibody titers than vaccination alone for both original strains and the Omicron variant.
