The UK's preparing to administer COVID vaccine booster shots, and Australia is set to follow suit

Preparations to roll out the vaccine to elderly populations from September are awaiting final medical advice, but the move marks a step in the global vaccine race as the UK turns its attention towards providing ongoing resistance to COVID-19 and new variants.
