It is just too risky to go there at the moment. Me and the Mrs have 3 jabs and still caught it from the son over Xmas. It is not life threatening to us but it spreads like wildfire very easily.
It probably would have been better to hold off until mid year 2022. Let this wave settle down and they will have a better handle on things then.
And I would not be bringing kids anywhere far, unless it was a life or death situation.
