Uh ... 17+ years is hardly a "rush".
As long as you don't mind taking the word of Captain Kangaroo about it...
The sad thing is that, just like he said, the virology community knew that a new SARS virus would emerge at some point and while there was some study on it. Very little. Time and time again SARS-vaccine projects were cancelled due to lacking funding. If we'd only listened to the scientific community we'd have had a Covid-19 vaccine ready in advance on shelves even before Covid-19 emerged. A general vaccine for all Coronaviruses. But we were stupid and shortsighted and waited until it was a disaster before funding it. This is partly what Gates speech in 2015 was about. The speech QAnon uses as proof of his part in a conspiracy. But Gates didn't say anything that the scientific community didn't know already.
So sure, we've studied it for 17 years. But very little. Not nearly as much as we should have
We couldn't have had a Covid vaccine ready before we saw it. SARS vaccine research was taken to the point before human trials and lacking any cases it couldn't possibly go past phase 1 trials at that point and there was little reason to even go that far. When Covid came along it took 2 days to make the first vaccine--the SARS prototype with a bit of different mRNA pasted in. Where's the failing?
This is just plain false. In fact it is false on the basis that the vaccine we do have is in fact built mostly out of the research that was done: this Covid vaccine model using mRNA is in fact capable of being applied to most, if not ALL other coronaviruses.
"Find the mRNA that produces spike proteins for (insert whatever coronavirus here), make a bunch of that, figure out how to preserve and deliver it, and that's all she wrote."
If we had made a vaccine to target SARS even in the absence of an actual SARS outbreak, we would have only had to swap out the spike protein mRNA in the system.
"Very little reason"? The whole reason this was being done was because we knew another variant would emerge. That reason precipitated in the form of a global pandemic and untold amounts of death and suffering and trauma. This would have not happened if we had actually listened to the experts on the field and pushed funding.
We should be nabbing bats (and mice, and rats, and ticks, and every other critter in the world that uses biological warfare to fight being eaten), finding out every last variant of biologically threatening virus, bacteria, and otherwise inside of them, and making vaccines for them.
We should be spending whatever money we can manage on it. Making huge industries around this pursuit.
