@ASlavitt There most certainly are "scientific" ways to keep up or stay ahead, including stacking scientific measures such as ventilation/filtration, de-densifying, masking, testing, tracing, quarantines, etc.
There is no scientific way to keep up or stay ahead with just vaccines.
@ASlavitt最肯定的是有“科学”的方法来保持或保持领先，包括堆叠科学措施，如通风/过滤、去密度、掩蔽、测试、跟踪、隔离等。
仅仅依靠疫苗是没有科学方法跟上或保持领先的。
