PLEASE, stop spreading the microchip nonsense 
One vial serves five doses of the vaccine, a little bit of it is wasted.

Stupid questions:
Which portion has the chip in it?
Are there enough chips in a vial that every of the five vaxxed persons is guaranteed to get one?
What if one or all persons gets more than one chip?
Will they connect and form a multiprocessor-unit?

WTF.
Common sense seems to become even more rare than liquid bitcoins...
