@barttels2 @ChristosArgyrop @big_guerilla @fitterhappierAJ @james1chas3 @BNODesk It was, perhaps not clearly. CDC said to continue mask mandates, quarantines, etc. Dec to May. WHO never said to drop measures. Fauci and several commentators (Gottlieb being one, probably others) said in 2020 that immunity would likely not last.

@barttels2@ChristosArgyrop@big_游击队@fitterhappierAJ@james1chas3@BNODesk，也许不太清楚。疾控中心表示将在12月至5月期间继续实施口罩要求、隔离等措施。从来没说过要放弃措施。Fauci和几位评论员（Gottlieb就是其中之一，可能还有其他人）在2020年表示，免疫可能不会持续。
