We check in with Roxbury Community College, where Tuesday afternoon, a mass-vaccination site opened at the Reggie Lewis Track and Athletic Center. Monday's snow storm delayed the opening by one day.

Boston Mayor Marty Walsh says the city expects to initially administer about one thousand vaccines a week there. The Commonwealth is eventually slated to take over the site, and scale the program up further. We speak with Valerie Roberson, president of Roxbury Community College.
