Covid 19 vaccine and Tocilizumab.

Hello. My Rheumatology Advice line has said that they are not accepting any questions about the Covid 19 vaccine so I wonder if you could offer any advice/help.

I had the Pfizer vaccine this week, which I am very pleased about. However, watching this evening's news, I see that Tocilizumab is now sometimes being used as a treatment against coronavirus. As I receive Tocilizumab Infusions every 4 weeks, I am a bit concerned and had a thought as to whether if me being on Tocilizumab, could possibly stop the vaccine from working? Or do vaccines work on a completely unrelated way? Any advice wlould be gratefully received. Thank you.
