Omicron breakthrough infection induces superior mucosal and humoral immunity to SARS-CoV-2 variants than booster vaccination

A CITF-funded study that presented results at the CITF scientific meeting in Vancouver, found that an Omicron breakthrough infection (an infection after a full vaccine series) induces a stronger overall immune response than booster vaccination alone. Both mucosal and humoral immunity contribute to the overall immune response to SARS-CoV-2.
