Hi, I'm booked in for vaccine on Sunday - and just wondering what vax I'll be given? I'm 41 and going to a mass vaccine center which I think has just run out of Modern and has switched to AZ. But I'm worried about AZ as family history of clots, and 37 weeks pregnant, and Moderna/Pfizer is advised in preganacy. Does anyone know if they have a few modena/pfizer kept aside for this situation? Or will I just be offered AZ? Thanks!!
