Absolutely false. I am not saying airports are a source of infection. What I am pointing out is that air travel is allowing for all these variants to propagate to new populations. The pervasiveness of the UK variant in Europe would have been contained or at least decelerated with travel restrictions. A living proof of this is both New Zealand and Australia. These countries still allowed for sea and air freight but banned travel. Both countries are roughly back to normal life, while we in Europe are still trying to blame pharmaceutical manufacturing vaccine output, as if that is the sole cause of our problems.
