The patent was for any jab to be in the air, no need to get a shot, just breathe it in. Ever notice almost everything is now scented? What do people do when they smell something good? Deep breathing, brings more toxins to your lungs.
Not only scented things, how many places and vehicles require air filters? Where are those filters made? Any protocol or control on how they are made? Last fall/winter I had to replace the air filters in my car twice, it seems the mice loved them... first time that's happened here.
