We normally see my 3 grandchildren (12, 14 and 17) only once a year since they live overseas. Haven’t seen them for over 2 years now because of COVID. Would love to see them this summer, but both their parents are vaccine phobic, and the rules ATM mean they can’t travel. We want to respect their parents right to choose, but it is heart breaking. We are fully vaccinated, but too I’ll to make the journey Advice?
