BRUSSELS (AP) — The European Commission says it has launched legal action against vaccine maker AstraZeneca for failing to respect the terms of its contract with the EU. A Commission spokesman said Monday that the reason for the legal action was that “some terms of the contract have not been respected” and that “the company has not been in a position to come up with a reliable strategy to ensure a timely delivery of doses.” The AstraZeneca vaccine has been central to Europe’s immunization campaign, but the slow pace of deliveries has frustrated the Europeans. AstraZeneca says that it “regrets” the Commission’s decision to take legal action and that it will “strongly defend” itself in court.
