But a lot of good people have taken it because they were told it was a good vaccine.

Sadly, all vax has Graphene Oxide in it from the past decade ... best option NOW for . E V E R Y O N E . is to please research DETOX for heavy metals, that will expel the aluminum, barium (chemtrails) and the nano Graphene Oxide which is deadly, destroys your blood cells causing blot clots in healthy young cells.
You can counter it, please do NOT remain passive.

President Trump said to get the vaccine but I don't recall him saying which vaccine to get. But then what is a "vaccine"?

Vaccines are a type of prophylactic, a preventative. When we think of vaccines what comes to mind is the type that introduces antigens into a person’s body in order to provoke an immune response.

But a vaccine can be something that does not use antigens but instead prevents infection via other means. A prime example is the combination of HCQ and Zinc (This is what Trump took). Zinc is the primary ingredient in this cocktail, not HCQ. Getting sufficient zinc into a cell will stop the ribosome in the cell from reproducing the parts needed to make a virus should the cell become infected. This is where HCQ comes in. It is a zinc ionophore and helps zinc get through the lipid layer that is part of the cell membrane.

This video explains how Chloroquine (or HCQ) and zinc prevent COVID infection.

Especially bad are the ones Nana thinks that took the jab EVEN AFTER receiving the information necessary to discern it was the wrong thing to do.
