psoriasis
"Back when Stelara was first approved for psoriasis, my dermatologist went ahead and put me on it.  I cleared in one shot, took the next 2, and we laid off.  Minor side effects - some swollen tonsils and sinus issues. Fast forward a year and half - went back on it - after my second shot, I spent the next 6 months going through a continual round of sinus infections that required injected antibiotics, and got confirmed influenza A despite being vaccinated.  Tests showed likely my immune system couldn't handle.  "
