Giuseppe MichieliNeutralising #immunity to #omicron sublineages #BQ11, #XBB, and #XBB15 in healthy #adults is boosted by bivalent #BA1-containing #mRNA #vaccination and previous Omicron infection, https://doi.org/10.1016/S1473-3099(23)00289-X
''Reassuringly, using a high-throughput live virus assay, we found that bivalent mRNA BA.1-containing vaccines substantially increased cross-reactive neutralising immunity against then yet-to-emerge omicron subvariants, including XBB.1.5, at titres that are compatible with a low risk of systemic illness''
