If you do have a deep interest in this it would probably help to learn immunology on a more detailed level. My suspicion is that articles like the one you linked feel unsatisfactory because they say things like this

> But if our immunity is “restructured” in some way every few months, we would again expect all viral infections to peak at the same time

It is clear the author doesn't have a good understanding of basic immunology.

Much of the mystique falls away when you understand concepts such as adaptive immunity (how it develops and is retained), antigenic drift, environmental conditions (on the host) that improve transmission, etc.
