A couple of days ago I wrote to Prof Sarah Mackie from Leeds who says:
" ... it must be particularly challenging for a board like HU with global reach. Plus, as you say, the advice from on high is constantly changing, particularly in countries where the prevalence of the infection in the community continues to rise (ie probably everywhere except perhaps South Korea/Japan!). We all are working with limited data with a lot of uncertainty.
We made a YouTube video for our rheumatology patients on immunosuppressants/steroids to explain our own local guidance further.
I personally think individuals faced with conflicting advice should check with their own doctor, and if it is confusing, in the meantime take the more conservative option. It’s not just what drugs people are on, it’s their past medical history as well."
This video takes you through the flow chart that has been available on the forum for some days step by step - it is impossible to get it wrong by misreading the small print!
Personally, I would NOT take a nurse's opinion if it disagreed with this. Nor a GP or anyone else being dismissive about your risk.
