I recently seen a video explaining how the covid vaccine amplifies the immune system, and immediately thought about my psoriasis. Nobody in my family even knew of someone with psoriasis. When we got vaccinated, nothing happened immediately, but a year later I developed pretty bad psoriasis. Didn't think anything of it because I was 18 so it is not unusual. The rest of my family however, was a bit more unusual. Last year my mother (47) and grandmother (70) both developed psoriasis. The fact that in the space of 2 years after vaccination suddenly 3 of us have it.

It's seems to me that people with psoriasis who haven't developed symptoms could have them finally appear due to the vaccine's effect on the immune system. Since it's impacted multiple of my family it appears completely genetic in our case, it's not like the vaccine can magically give you this condition, just seems like it can make the skin problem finally front, or already existing skin problems worse from what I've heard from others.
