T-cell reactivity to the SARS-CoV-2 Omicron variant is preserved in most but not all individualsT cells from most SARS-CoV-2 infected and/or vaccinated individuals have preserved reactivity to the Omicron variant and reactivity is enhanced by booster vaccination. However, approximately 20% of individuals have reduced T-cell recognition of the Omicron spike, potentially due to escape of HLA class I-restricted epitopes.T cells from most SARS-CoV-2 infected and/or vaccinated individuals have preserved reactivity to the Omicron variant and reactivity is enhanced by booster vaccination.
