Ontario COVID sequence updates have been more frequent over the past month with the XFG.* "Stratus" family of variants now at 74% of sequences, NB.1.8.1.* "Nimbus" at 22% and LP.8.1.* down to 3%.
Looking at specific variants as of mid August, XFG.5.1 is most prevalent at 13%, NB.1.8.1 in second at 10%, XFG.2 in third at 8.6% and XFG.3 in fourth a

How different is LP.8.1 compared to the current XFG.5 variant circulating in Ontario?
You can see from the Venn diagram that LP.8.1 has 4 different amino acid mutations that aren't in the XFG.5 or JN.1 spike protein, and XFG.5 has 6 amino acid mutations not present in the other two ( https://cov-spectrum.org/explore/World/AllSamples/AllTimes/variants?nextcladePangoLineage=JN.1&nextcladePangoLinea

LP.8.1 is what this fall's Japan Novavax vaccine and the mRNA vaccines are designed for which is now almost gone and typical of how these things work with vaccine manufacturing timing while Novavax is providing the previous year's JN.1 vaccine formula for the USA again.
LP.8.1 is a descendant of JN.1 from several years ago which became KP.1 before it became LP.8 as seen in the Sankey diagram. Last
