Optimism that vaccines will help revive the economy in 2021 got another boost. On Monday the University of Oxford and AstraZeneca said their vaccine was found to be as much as 90% effective in preventing infections without serious side effects in a large trial. Unlike shots under development from Pfizer and Moderna, AstraZeneca’s vaccine can be stored at temperatures above zero degrees Celsius, easing the distribution process. U.S. stocks climbed Monday, with the Dow Jones Industrial Average rising 1.1%. American depositary shares of AstraZeneca shares fell 1.1%, as some investors appeared to be disappointed that its vaccine candidate’s effectiveness rates fell short of those reported by Pfizer and Moderna.
