I believe it's back on standby as is the one in my city, Nightingale Hospital North West, in Manchester. The issue is staff though, there simply isn't enough qualified staff to work it alongside their hospitals.

I've been working as a volunteer nursing assistant in hospital A&E departments through St John Ambulance it's honestly just insane. I don't know what the plan is for Nightingale but we're focusing on getting mass vaccination centres setup currently and delivering the vaccines.
