If they tried to get it into your food, etc. it would be excreted out. In the circulatory system it is going to have to come out in a different way.
Let’s look at it this way. The polio vaccine was an oral vaccine.
Most other vaccines are injected. This graphene injection - well, if it makes you arm magnetic, and it clots the blood and causes heart conditions, and other things....
I don’t know how you body would uptake graphene through your intestines. But this is really interesting.
If you look at nano zinc previously used in sunscreens, you’d find the zinc particles were so small they went through skin, so most all such sunscreens started using bigger particles.
