That's a tremendous amount of misinformation to pack into a single sentence!
There were several companies working on "old school" style vaccines, they take longer to develop!
And at least one of the old school style vaccines proved to be less safe than the mRNA vaccines and was withdrawn from market, precisely because there were safer vaccines out there so there was no reason to let a less safe version be sold, even though it was still far better than nothing: https://www.science.org/content/article/rare-dangerous-side-...
Further, the very concept of "old school safe tested ones" doesn't even make sense with respect to COVID, because there were no COVID vaccines before COVID existed, and every single vaccine must be tested to evaluate safety.
Further, the concept that "its more difficult to produce inactivated vaccine at mass scale" is at best unsupported for the current day, and back in the early day it was 100% false. Mass producing mRNA vaccines was extremely difficult. They were very quick to design and get a prototype, but mass production was a new and very very difficult effort.
And as for "the reason why they were producing mRNA vaccines" is that the "they" there was a company that focused on mRNA vaccines so of course they would work on that. And the advantage of mRNA is that it is able to be designed and engineered with purpose, rather than the random chance of trying to get an inactivated vaccine, which is far more laborious and slow.
It's so weird to come into these threads on HN and have people just pack so much falsehood into so few characters. Such false information should not be left up uncountered, but it's exhausting to even list what's wrong, much less show all the evidence.
