I thought about it a bit too and it's a version of a solution to the prisoner's dilemma from game theory. Pelosi is done after this and indebted to China / dependent upon semiconductor boom. Biden is also indebted but has chosen to use covid to create plausible deniability. Thus, they orchestrated a solution that will either work or backfire historically in which case either they are insulated or sunset
They're using it as a way to save face in case they want to change plans last minute. Like someone who cancels a date last minute because they found a better alternative and then comes up with working late or some other excuse
Biden "tested positive" for Covid... again. Remember when Pelosi tested positive for Covid and last minute had to cancel a controversial trip to Taiwan last year? Now she's headed to Taiwan and Biden has last minute gained an excuse to nope out and go underground for two weeks.
Vaccination derives from a word with the root aca meaning cow. Prior to modern medicine people knew they could mediate the likelihood and severity is illness through exposure. They would use cows to develop immunity and then acquire immunity from the cows. So, this demonstrates that immunity can be shared in cases of inoculation. I'm more skeptical, in general, to some of the more modern protein based approaches. I think they don't understand the long term effects (being generous) or may have an agenda.
It's a badge of honor.
