Like the Swedish data, it suggests that the new vaccines targeting XBB.1.5 should help protect against BA.2.86 too.

These two charts are neutralization data from XBB breakthrough infections. First chart is involving people that previously received the BA.5 bivalent booster. The second chart is involving those who did not.

Note though this was with pseudovirus, so caution should be exercised as the actual virus may behave differently.
