@benny171a @lotzof_gas @activia513 @krtmd @jonathanchait IT IS THE SAME VACCINE WITH AN UPDATED STRAIN.
I don't know what part of that is hard to understand. The strain update has only been tested in animals, as is done with flu shots. The vaccine itself, with earlier strains, has been tested in clinical trials.
@benny171a @lotzof_gas @activia513 @krtmd @jonathanchait 它是相同的疫苗，具有更新的菌株。
我不知道其中哪一部分难以理解。菌株更新仅在动物身上进行了测试，流感疫苗也是如此。疫苗本身和早期的毒株已经在临床试验中进行了测试。
