Covid Vaccine while having Dermagraphica?

Has anyone taken the Covid 19 vaccine while having Dermagraphica? Or taking meds to control it, like an antihistamine? I have Dermagraphica and am trying different anti-histamines to control it. Wasn't sure about the vaccine and how it would react with all the histamine in my body.

Vaccines are usually safe but this depends on the physical health of the person.
