Abstract：
Durability of variant neutralization in solid organ transplant recipients following Omicron-containing boosters is unknown. We report wane in XBB.1.5 neutralization by 3 months following a first bivalent booster, improved by a second booster; hybrid immunity improved peak, and duration of neutralization. Boosting at 3 to 6 months appears necessary to maintain neutralization.
摘要：
在含有Omicron的助推器后，实体器官移植受者中变体中和的耐久性尚不清楚。我们报告说，在第一个二价助推器后3个月，XBB.1.5中和逐渐减弱，通过第二次助推器改进；混合免疫提高了峰值，和中和的持续时间。在3至6个月时增强似乎对于维持中和是必要的。
