That‘s why I am also a bit puzzled, beta strain is a bit more in France yes, but it‘s not like it‘s suddenly a problem this month, as the rate in France is comparatively consistent (maybe due to their African travellers and communities?), unless there are data that we cannot see.Still not seeing any reason a double vaccinated, double tested person would need to quarantine. As I’ve said we are the problem for Europe.
I have to say I don‘t think the "scientific" decisions of traffic light system is transparent enough. We have said it from 2020, other scientists should be able to see the data, and more importantly, their standards, too.
And sorry to hear that you have to give up your travel plan.
