Though KP.2 was probably the most dominant variant earlier this summer season, it’s been knocked right down to sixth place whereas its offspring at present dominate. Analysis has proven all three up to date vaccines are simpler at defending towards the JN lineage than the at present accessible XBB vaccines, which have been accredited final 12 months. When in comparison with its XBB vaccine, Pfizer’s KP.2 COVID-19 vaccine provided as much as a 7.3-times stronger response in mice contaminated with KP.2 and a number of other different JN variants, in accordance with trial data. Moderna’s KP.2 vaccine was as much as eight times simpler at defending mice towards JN variants than its XBB.1.5 vaccine. Novavax scientists gave mice an XBB.1.5 vaccine after which administered the JN.1 shot 11 months after. The JN.1 vaccine was as much as 48 times simpler at defending towards the JN lineage than the preliminary XBB.1.5 shot.
