In this case, I don't think it's necessary to go into too much detail about how the immune system works. The issue is that if you are going to _some_ level of detail, then you need to include all the relevant context. In this case, the number of antibodies that the immune system can produce goes along way to explain the points made in the rest of the article. PS I am aware how damn complex the immune system is and how complicated it can be to explain to people at the right level of detail. I once attempted to watch a lecture on how the spike protein and antibodies work which went into detail on all the chemical reactions that occur at each step and it is just insane how much complexity there is to it. And that was presumably a simplification of what actually happens.
