How long are we immunosuppressed for after treatment has ended?

I finished chemo in February and radiotherapy in March.I’ve been on Anastrozole since April and have my 18th ( AND FINAL) Herceptin in 2 weeks.

Im a teacher and we have possible cases of scarlet fever in my school. My head teacher has asked if I’m still immunosuppressed but no one seems to know.

A blood test should be able to tell or your oncologist should be able to give you an idea… But at any rate not all chemos destroy your immune system. I was on taxotere and cyclophosphamide and had a filgrastim injection each cycle. My immune system tanked about eight days into each cycle but would then recovered by the time my next cycle started. So for me, I was considered fully recovered three weeks after my last treatment.
