A non-technical detail that the post misses is the human story here. Katalin Kariko, the biochemist that pioneered the idea of delivering vaccines in mRNA form, got nothing but rejections for her grant applications for this very idea and was eventually demoted from tenure track at U Penn.
Whatever you think of this, it's a misleading understatement to describe it as:
> As with other fundamental scientific research we are now reaping the benefits of, the discoverers of this technique had to fight to get their work funded and then accepted.
From the article[0] the post itself cites:
> By 1995, after six years on the faculty at the University of Pennsylvania, Karikó got demoted. She had been on the path to full professorship, but with no money coming in to support her work on mRNA, her bosses saw no point in pressing on.
