AstraZeneca has revised down vaccine efficacy data after doubts were raised over its U.S. trial results. The pharma giant is also at the centre of the ongoing vaccine export row between the UK and EU. But, London and Brussels are looking to ease tensions and ramp up supplies across the continent. In market news, U.S. equities fall with the Nasdaq leading declines, despite 10-year treasury yields also heading south in a sign that the recent trading trend could be slowing down. Chinese tech stocks fall as well after the U.S. Securities Exchange Commission rolls out a Trump-era law aimed at forcing de-listings over auditing irregularities. Beijing is also under pressure from U.S. Treasury Secretary Antony Blinken who urged NATO allies to collectively push China to uphold its trading commitments.   See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
