I don't think you understand how immunity works Shooty.

I didn't understand either, so I spoke to a close friend of mine who is an infectious disease specialist. 

First, there are many types of immunity. 

A vaccine is created to "train" the body to react to one of several parts of a virus. Sometimes it can be a toxin that is produced, or in the case of Covid, the spike protein.

It simply trains the body to recognize some aspect of the virus; that's the leukocytic immune system. It has a memory, either through a vaccine, or from having "seen the actual virus" before, to mount an attack when it sees the foreign antigen.

What's more, most people think of the antibody response from a vaccine. A UPENN study shows the mRAN vaccine also trains the T-Cells to mount a very heavy response to the virus; teh T-cells are the armor of our immune system.

You're not taking from one one pot to help another pot. These are all debunked theories. In the last 2 years, i have not even gotten a cold. I'd say my immune system is pretty good. I never even tested positive for Covid this past weekend, but I had a headache and was fatigued. Not sure if my system just never sero-converted and was busy fighting the onslaught of covud ... My friend did test positive. That said, he was coughing a lung and I was fine after 48 hours.
