The researchers who developed these modern mRNA vaccines will now become the defenders of the new status quo .
All their reputation hinges on the vaccines being DECLARED safe for human use.
Are they safe long-term? Who knows, it's a huge business now. So it's not in the best interest of the aforementioned scientists to look too hard for it might tarnish their current reputation, influence and abilities to receive funding or make profits.
