(AP) — World stocks and Wall Street futures are up after more good news on potential vaccines but unease about anti-coronavirus restrictions on businesses. AstraZeneca said Monday that late-stage trials showed its coronavirus vaccine was up to 90% effective. The company is the third major drug maker to report late-stage results for a potential COVID-19 vaccine. That helped ease some investor concerns about decisions to reimpose anti-virus controls in the United States, Europe and some Asian countries. A new survey shows that those restrictions caused economic activity to drop in Europe in November, though the outlook has been brightened by the vaccine news.
