After more than three billion doses, the Oxford-AstraZeneca Covid vaccine is being withdrawn.
AstraZeneca said it was "incredibly proud" of the vaccine, but it had made a commercial decision.
It said the rise of new coronavirus variants meant demand had shifted to the newer updated vaccines.
Its vaccine was estimated to have saved millions of lives during the pandemic, but also caused rare, and sometimes fatal, blood clots.
In the race to lift the world out of pandemic lockdowns, the Covid vaccine was developed by scientists at the University of Oxford in record time. A process that normally takes 10 years was accelerated down to about 10 months.
