Novak Djokovic is in Australia, preparing to compete at the Australian Open after last year’s preposterous dismissal because he wasn’t vaccinated.

But come summer he may miss another US Open because Joe Biden still has the United States on the embarrassing list of countries that still ban billions of people from visiting based on their vaccination status – a completely nonsensical policy since being vaccinated has no impact on the spread of the virus.

China will be off that list on January 8, when its travel ban and strict quarantine requirements end.
