Nano Vaccines are ultra-small particles about 1/200th the width of a human hair, combined with all or part of the disease causing microbe to trigger the body's immune system. I'm talking about aerosol vaccines...

Mass Inoculations of the Public.

Sweat-triggered vaccine delivery, nanoparticles that penetrate the skin through hair follicles and burst upon contact with human sweat to release vaccines.

What will we expect to see?

How far will this go? Will airports use air conditioners to inoculate every person who passes through?
