I came across this medical research that has NOT been peer reviewed, from scientists in Germany and the Netherlands. They studied the Pfizer COVID vaccine and found that it reprograms innate immune system responses to a whole host of stimuli from fungi to viral infections to bacteria. Changing how we react to things that go well beyond just COVID.
The Pfizer vaccine potentially permanently alters the immune system in ways that are not fully understood. The research shows the anti-inflammatory response to stimuli was reduced. That's a double negative equalling increased systemic inflammation. And systemic inflammation is the root cause of Alopecia!!
I'm trying to tamp down my immune system so it stops attacking my hair follicles. The COVID vaccine seems to work contrary to this goal, at least in this research.
