Good news for those with Long Covid and those that refused the vaccine and thought they were okay because of their superior immune systems and not dying. It was always a dice roll since no two people are alike. Without this finding, they would have been an extreme burden on the medical community and society as a whole.
Come to think of it, they identified the problem but no solution was mentioned. Treatment is going to be another matter, but best of luck in that regard.
So, yes, I've always said that we're no where near our abilities to measure everything. Anyone who says that is chock full of hubris just because they can measure a few things and understand the results.
What they're understanding are the results of some limited tests. That's all.
All the best,
