So my brother met his now fiance 5months ago.She's from C19 Omni central in London and has a daughter 9 they have travelled up here for Xmas . I am very vulnerable to C19 as I have a generic disorder meaning though I've been double and boosted i m Still vulnerable to catching and getting ill if I caught this disease.We don't Know my brothers girlfriend fiance .My parents are in their 70s. Because of her she is not only putting my parents more at risk, I can't see them at all this Christmas as I would have done.Because it takes a fortnight for symptoms to show.My brother is Selfish and neither will do a lateral flow even before they go.AIBU?.
