Pfizer has slashed by half the volume of Covid-19 vaccines it will deliver to some EU countries this week. Reuters has reported that Romania, Poland, Czech Republic have all expressed frustration over the announcement by the US drugmaker. Officials of these govts have said that the deliveries will not return to normal until the end of March. With governments across Europe still reeling from the surprise cuts, officials say the reductions are undermining their efforts to inoculate their citizens and tame the pandemic which has killed more than 2 million people. On Wednesday, Italy threatened legal action against Pfizer.
