The difference between the virus and the injections are the viral load (number of spike proteins).

If people have a functioning immune system, the number of spike proteins in their system (viral load) remains small. A proper immune system prevents the virus from replicating out of control, and clears the virus from people's systems... after which they have natural immunity, clearing the virus even faster if another infection occurs.

Add in early treatments (the IVM, HCQ, D3, zinc, etc.) which hinder the virus while simultaneously boosting the immune system, and the clearing of the virus plus natural immunity occurs even faster.

The injections, in contrast, introduce a huge load of spike proteins many, many orders of magnitude greater than the average viral load of an infection... and then damage your immune system so that the next time a person gets infected with the virus, it is allowed to replicate out of control causing another huge viral load.

So, a viral infection is quickly suppressed by a healthy immune system, and causes little or no damage (most of which can be repaired if it occurs, the exceptions being the brain and heart).

The injections cause much more damage all by themselves, and then allow viral infections to also cause much more damage due to the impaired immune system not clearing the virus - allowing huge, asymptomatic viral loads (the igG4 problem, and so on).
