This shows the extent of the ideological capture of institutions by zealots. I'm very glad this is now being done, but anyone with a shred of sanity realises that this should have happened from the very beginning.
If you're going to be experimenting on healthy bodies, especially of children, then you should have had all the protocols set up in place so researchers could carefully track outcomes to ensure people were getting the right treatment.
Anyway, as other posters have said, the zealots are very confident that experimenting on healthy bodies leads to excellent results, so they should be fully on board with researchers finally being able to show proof that they were right all along.
