@boodad12 @TrumpUndead @jonathanchait Yes and no. It's the same formulation that has been used for two years modified for a different strain. That's the same method that is used with flu vaccines every year. You don't have to retest the same vaccine for every new strain.
@boodad12 @TrumpUndead @jonathanchait 是也不是。这是相同的配方，已经使用了两年，针对不同的菌株进行了修改。这与每年用于流感疫苗的方法相同。您不必为每种新毒株重新测试相同的疫苗。
