“We’ll grab your jabs” is the headline on the Metro, which says the EU has threatened to block exports of Covid vaccines. The paper says that despite several EU countries halting the use of Oxford-AstraZeneca jabs, European Commission President Ursula von der Leyen says the company has slashed the number of UK-made vaccines it will deliver to the bloc. She has threatened “reciprocity” by making up the shortfall by stopping shipments of the Belgian-made Pfizer-BioNTech vaccine to the UK.
