I don't know where this narrative comes from, but it can't really come from anybody who specializes in making brand new technologies.
There are soooooo many amazing technologies that have never been brought to market because of the roadblocks like this vaccine encountered.
It's even amazing that mRNA vaccines actually made it to the market, and if it hadn't been for the pandemic, there's a good chance that it would be another 15 years before they do, and this mRNA vaccination tech has been brewing since the 90s, I think? Years before the pandemic, I knew of Moderna and BioNTech because they had the capability to make customized therapeutic vaccines to train a person's immune system to fight their particular cancer's unique neoantigens. The hurdles seemed somewhat enormous even then for them. Without the kick start of money and trials that the pandemic provided, it would have taken so many more years to do the discovery needed.
The problem is that we have a massive unexplored terrain in R&D and trivial amounts of funds compared to the area we can explore. We have to be extremely picky about what gets money to move forward. This is a social problem, as much as a finance problem, we simply use dollars to express our societal wishes of what we want to encourage.
In the mean time, it would be good if the media would stop spreading the idea that if you build a better mouse trap, the word will bear a path to your door. It's quite the opposite.
