These are just regular guests that she's asking for help.... She has bridesmaids and groomsmen btw

I'm in quite a pickle here. I have a wedding coming up last weekend in July. At our venue, deposits have already been put down and contracts signed, and our venue is not letting us change the date at all no matter how much talking and convincing we do. We're slightly confident things may clear up by then, but a lot of my guests are asking me if the wedding is still happening, and I've had a couple even back out.  I don't quite know what to tell them yet, that's what I need help with. Our wedding date is far enough out that I don't know how things will be by then, but close enough that I, along with many of my guests are worried conditions won't be safe by then. I also feel like even if I could postpone it, which the venue isn't letting me, I also don't know what date would be safe to postpone to. Everything is just so unpredictable with this virus and I need help
