Does anyone know how long 6mp stays in your system after you stop?

I have been on 6mp and in remission for many years. I stopped taking it 3 weeks before my first Pfizer shot, and have been off it since. Almost 3 weeks now since my 2nd shot. Does anyone have any info on how 6mp affects the efficacy of the vaccine?

@nlkirby66 Welcome to Mayo Clinic Connect, a place to give and get support.

You'll notice I moved your question to an existing discussion on 6mp. I did this so you could connect with members like that have experience with this topic in a central location.

I'm wondering if you might be best served to post a question in the COVID-19 group. What do you think?

I have linked the COVID-19 group below.

May I ask what guidance your provider has given you and if you've found any information online regarding this topic?
