T-cell response to Omicron after an mRNA COVID vaccine booster

In a recent prospective observational study posted to the medRxiv* preprint server, researchers determined Omicron variant-associated T cell responses before and after a third dose of messenger ribonucleic acid (mRNA) vaccination against coronavirus disease (COVID-19) in anti-CD20-treated multiple sclerosis (MS) patients.
