More than seven million people use insulin in the US, but the strong demand hasn't stopped manufacturers from slapping it with a hefty premium. Fortunately, manufacturer Eli Lilly and Company has agreed to slash costs by 70% from May and cap the cost at $35 (£28) a month following action from the Biden administration.

Although the reductions will only apply to older insulin products, the move brings the typical price per vial – which has climbed to $100 (£79) in America – more in line with average costs per vial in Canada and the UK. These stand at just $12 (£9.50) and $7.52 (£6) respectively.
