“They took animal viruses that only occur in animals and they increased their transmissibility to humans,” Rand Paul

So the Corona Virus only occurs in animals and now by taking the jab your cell is able to recognize and interact with the spike protein.

That sounds like gain of function to me.

Without the jab the corona would have just bounced off your cells as it has done so for millions of years. Now because of the jab it can interact with your cells generating endless seasonal variants like the flu.

Even the notion that the jab reduces the severity of the infection rather than prevent it is telling.

Humans naturally do not get infected. A jab that reduces the severity of infection is also implicitly allowing for and improving the infectivity of said virus.
