I think the state of emergency allows to cut the time short, because these are very short time frames for clinical trials.
To risk "conspiratorial thinking" charges, what are the odds that in a country with 31% unvaccinated adults, only 2 participants in the control arm of a critical RCT didn't want to take the vaccine as soon as it was offered?

Edit: The study the NYT article references:

Edited the numbers to reflect the original source.
Really, large numbers of highly educated people who do this for a living have been arguing about this. We want to do better but we're restricted by human ethics and public opinion.
Edit. Really, the only point I want to convey is that perhaps the highly intelligent and educated people could reflect on why RCT population of the covid studies don't seem to reflect the country population for the particular dimension of taking the vaccine as soon as the RCT ended. Perhaps this can be fixed somehow. This is as kind of a suggestion as I can muster. Perhaps they already do, and then all of this is moot.
When you say "got away with it" it sounds like you think they were intentionally carrying out a conspiracy theory. The reality is far more banal.
