Corona is Latin for crown.
"They" want to vaccinate us to prevent us from receiving the "crown".
That is what the end is about. Preventing people from receiving their crown by means of pharmakeia.

They are displaying their entire plan to the world.
This is not about a literal virus and a literal vaccine.
It is about literal 666 in your hand and in your forehead.
