OAKLAND —  People dining inside restaurants in Oakland or visiting other indoor public gathering spaces such as gyms may have to show proof that they’ve been vaccinated against COVID-19 if the City Council approves an emergency ordinance on Tuesday.

The ordinance, proposed by Councilmember Dan Kalb, is similar to ones adopted several weeks ago by San Francisco and Contra Costa counties and the city of Berkeley.
