Nonetheless, over the previous two months, three new subvariants (referred to by some as FLiRT) have emerged from JN.1 and now account for over 70% of circumstances. These subvariants — KP.3, KP.2 and LB.1 — possess a number of mutations within the gene encoding for the spike protein, which is focused by antibodies generated by Covid-19 vaccines.
These mutations permit KP.3, KP.2 and LB.1 to extra successfully evade the immune system, and doubtlessly unfold extra effectively. For individuals who obtained their final vaccination in 2023 or skilled a pure an infection greater than 6 months in the past, it’s much less possible that their immune system will keep off an infection by one of many new variants. This hole in particular immunity in opposition to KP.3, KP.2 and LB.1 helps drive the summer surge in Covid-19 circumstances.

Are The New Covid-19 Subvariants Inflicting Extra Extreme Illness?
