The economic outlook in the eurozone remains "clouded by uncertainties" because of the coronavirus pandemic, but an accelerating vaccination campaign should bring about a "firm rebound" in 2021, ECB chief Christine Lagarde said Thursday. "Persistently high rates of coronavirus infection and the associated extension and tightening of containment measures continued to constrain economic activity," she said, but as more people are inoculated, the resulting easing of restrictions could "underpin the expectation of a firm rebound in economy activity in the course of 2021." hmn/kih/wai
