Alameda County remains in the orange tier of the state’s blueprint for reopening the economy amid the COVID-19 pandemic, a public health official said Tuesday.

State officials are doing away with the tier system on June 15, and it wasn’t clear Tuesday at the county Board of Supervisors meeting whether the county will move into the less restrictive yellow tier before then.

Santa Clara County moved into the yellow tier Tuesday and at least one other Bay Area county was already in the yellow tier.

In a weekly briefing to the board by public health officials, Colleen Chawla, director of the Alameda County Health Care Services Agency, said there was a small jump in coronavirus cases recently.

It wasn’t a surge, she said, but a hump that has now subsided.

Chawla said county youths 12 to 15 years old can now get vaccinated.

That can be done by health care providers at the Alameda County Fairgrounds and at UCSF Benioff Children’s Hospital Oakland by signing up at

Youth can also get the vaccine at sites in Berkeley, which has its own public health department.

Distribution of the vaccine at the Oakland Coliseum will end on Sunday and at the fairgrounds on June 5.

Nearly 57 percent of county residents 16 and old are fully vaccinated, Chawla said.
