Not sure that's quite right, certainly as far as Europe, Caribbean islands and many Far Eastern countries/Aus/NZ are concerned. If we assume that the UK/ Europe are vaccinated by the summer and countries and airlines operate a vaccine certificate system I can see things getting significantly better in summer 21. Most of the Caribbean and Australia and New Zealand have a much smaller problem anyway. Yes, the US because of it's size and the way the pandemic has been mismanaged will probably take longer but Biden has made it clear CV19 is a top priority so I think they will not be too far behind.
