Even though I agree with what you write. Logically your premise doesn't neccessarily hold up. All the ways we've already signed over our information willingly doesn't not preclude nanochips in the vaccine.
However I do believe there are no tracking chips in the vaccines. I believe we have been co-opted by Big Pharma for many years - especially with regard to our immune system. One of the reasons for this is Americans and modern peoples don't take care of themselves for all the usual reasons: overweight, inflammatory diets, addictive behaviors (not necessarily drugs), cut off from the natural world (no bare-feet in the dirt) and / or living a life that is out of balance.
We have been taught to trust doctors sometimes to the point of religiousness. I have had friends who have had COVID and recovered at home without any medical interventions other than the minstrations they gave themselves. It seems to me that the primary concerns of Big Pharma is profit first and health second. The more insidious agenda is a long-term dependency on Big Pharma than a healthy balanced lifestyle with a healthy immune system without flu vaccines.
