roth. joining us now, with more on that warning, and also what we learned today about the state's vaccine supply. rob. right alice? well dr mark galli says the good news is we appear to be coming out of this latest or the worst of this latest surge, but the bad news is the vaccine supply. is on short supply at this mass vaccination site. the mass was not very big tuesday here in the parking lot of san francisco city college, only 500 people received their shots in a place that can easily handle 3000 vaccines a day. the reason why we're not doing that is really vaccine supply. and because of the erratic and the, you know, unpredictable supply that we're getting in san francisco were unable to meet that full capacity and our full potential here today as well as throughout the rest of this past week. it's the same complaint from county's health care providers and those eligible for vaccines. but who can't get one? so we're trying our best to be patient. however it's really tough when you have all these folks here in san francisco who are eligible to be vaccinated but are unable to be vaccinated because we don't have the supply. a
