Is this [their] attempt at rolling out Immune System As A Service [ISAAS]?
Suppose the first shot reduces immune system efficacy on average by 26%.
Suppose the second shot reduces immune system efficacy on average by 37%?
What if [they] then declare that the definition of "fully vaccinated" is a dynamic, rolling definition?
Those with two vaccines will then have to take the third shot to remain in the system's good graces.
How many shots before the "fully vaccinated" have effectively no functioning immune system?
Are they then on a treadmill that they can't afford to get off?
