The practitioners who report these observations, including me, see them in patients over a broad range of ages, weights, etc. In other words, it's not just the older, fatter, male patients for example, who necessarily take longer to recover. In fact in my practice, the vaccinated individuals who take the longest to recover and who catch one cold after another, fit into the 30-60 age group, male and female, and have relatively active lifestyles.

I wonder whether you really believe that these demographic factors actually disprove the link between the study I posted and the observations of doctors. I suspect that you might be looking for some reason, any reason, to discredit what the science says. The study I posted showed clearly that repeated Covid vaccines reduce the virus-fighting immunoglobulins and increase the ones that don't fight viruses, thereby positing a rational explanation for the observations of the doctors. That doesn't impress you though because it seems to contradict the narrative that you have chosen to believe. The science matters less than your faith in how good these vaccines must be.

In defending what you believe, you even go so far as to imply that doctors and patients can't tell when a person has recovered from a cold or flu. i.e. that recovery from that physical ailment is purely subjective. That suggestion is rather silly but not surprising in a debate about Covid.
