I have sarcoidosis, an autoimmune disease, what are the risks of vaccines for covid?

I noticed on the Pfizer website that it was better to consult a specialist before getting vaccinated if our immune system was deficient and/or if we had conditions such as coughing, shortness of breath, fatigue. I have sarcoidosis of the lungs and since I have the above mentioned conditions, isn't it risky to take a vaccine if our immune system is already dysregulated? I am trying to avoid any stimulation of my immune system in order to control the progression of the sarcoidosis and I assume that there must not be much clinical data on the effects of the vaccine for people with sarcoidosis given the relative rarity of this disease. Thank you,
