Why on earth would you just hold on to doses until they expire when you've already decided not to use them?
Yeah, that’s not great but as has been suggested, it’s maybe not as simple as it first appears. we’ve also donated millions of doses and traded stock so countries without vaccines could get some earlier (Australia being an example). We funded Oxford development and helped secure a not for profit deal with AstraZeneca. Basically compared to a lot of developed nations we’ve done a decent amount for the greater good during the pandemic*
*certainly when compared to Macron, US/Pfizer etc
