COVID-19: European Medicines Agency's vaccines chief says it is 'increasingly difficult' to say no link between Oxford jab and rare blood clots

The European Medicines Agency's (EMA) head of vaccine strategy has said it is 'increasingly difficult' to say there is 'no cause and effect relationship' between the Oxford-AstraZeneca jab and 'rare cases of unusual blood clots'. However, Marco Cavaleri did tell an Italian newspaper that full evaluation work was still 'far from being completed' and that the risk-benefit ratio was still in favour of the vaccine.
