Because it isn’t a vaccine?...
This is NOT a vaccine in the traditional sense. It is a DEVICE that MANUFACTURES COVID IN THE HOST. Even WORSE, unvaccinated individuals are INFECTED BY VACCINATED INDIVIDUALS because it is the vaccinated individuals who become COVID SPREADERS.
If you are unvaccinated, STAY AWAY FROM VACCINATED INDIVIDUALS as they are more of a COVID THREAT than the air at large itself.
