We found that COVID-19 RNA vaccine-induced memory T cells exhibit preserved responses to the Omicron variant. These findings suggest that memory T cells will exert effector functions against the Omicron variant during breakthrough infections among individuals immunized with COVID-19 vaccines.
We analyzed the distribution of outer membrane (OM) attachment mechanisms across the whole tree of Bacteria, and we made a hypothesis on how gram-positives might have emerged. We tested it by perturbing OM tethering in the diderm Firmicute Veillonella. The results surprised us!
