Bay Area business bellwethers such as Apple, Tesla and HP saw their share prices climb Monday as an upbeat report about a coronavirus vaccine trial spurred big gains across Wall Street.

Biotech company Moderna said Monday that an early stage trial of its coronavirus vaccine produced antibodies for COVID-19 in all 45 participants who took the medication over a month-and-a-half long period. It’s the first time a company has released data about the results of a coronavirus testing trial on humans.
