But flying in and out of the U.K. has public health consequences
Yep, even now both pros and cons in proportion, you've got researchers/academics flying in/out, (thats why those involved in clinical trials, medical evacuation and covid related research get a waiver from quarantine )..people flying out to get healthcare in countries abroad..
logistics,Vaccines/vaccine components/PPE/other medical bits and bobs being flown in, as belly cargo on passenger flights......
Simply closing borders/banning travel (which some are calling for) could have a detrimental effect on public health...
