Some very self-centered people with very narrow views that think they have done it hard during this World Wide pandemic.
Pretty much no country other than North Korea has enough immunity to open up yet and many other countries simply do not have the resources, funds or capability to vaccinate even a small percentage of the citizens that want to get vaccinated - for many it will only ever be a dream to get vaccinated.
Here in Australia a first World nation we have hardly touched the surface with vaccinations (so much so it is embarrassing).
Yet the High and Mighty think that just because they have been fortunate enough to get vaccinated, that the World should instantly open up just for them!
Bugger the rest of the World Citizens, that you can easily infect by carrying the virus to what even destination you feel you have the right to visit.
Must love the self-righteous arrogance of some.
