If you document the design and process, somebody else can copy it.
I was involved in a relatively simple tech transfer of a pharmaceutical agent to a plant in China. We pulled it back to the US because every single batch failed. And it wasn't due to shoddy workmanship since we had US people on the ground directing everything.
That's billions of people who will be incubating more mutated variants of COVID-19.
And secondly, we'll need that equipment for COVID-19 variant booster shots.
(And will come in handy for vaccinating with a universal flu vaccine, even HIV, etc.)
What everyone else seems to be saying is that Covid-19 has a bus factor of like 5 or 6 people, who if they died,would lead to any breakdown in the process becoming an irrecoverable incident.
That single point of favor needs to be distributed, not just for production capacity, but for the future safety of the human race.
Call me skeptical. I think it's much more likely that this falls under trade secrets.
