AstraZeneca PLC promised the world more vaccines, at a lower cost, than any of the more established vaccine makers. It is finding how hard living up to those commitments can be.

That is already months behind schedule after a separate standoff with the Food and Drug Administration in the fall over disclosures about the vaccine’s U.K. trials.
