San Francisco’s public health department said it will shutter its two high-volume COVID-19 vaccination sites for the next several days over “limited, inconsistent, and unpredictable” supply.

In a statement Sunday, officials said the city’s sites at Moscone Center and City College of San Francisco had boosted vaccine provision by the department, pharmacies and healthcare providers to an average of 7,400 doses over the last seven days.

Those numbers helped raise the percentage of the city’s population over age 65 to receive a vaccine from 31 percent at the start of last week to 47 percent.

But dwindling supply is forcing hard choices, including closure of the city’s Moscone Center site for one week. That site, run in partnership by Kaiser Permanente, Adventist Health, the California Medical Association, Dignity Health, Futuro Health and the California Primary Care Association, will reopen once enough vaccines arrive to resume efforts.

The City College site will pause this week before re-opening Friday, but only to provide second doses. A third high-volume site at the SF Market in the city’s Bayview neighborhood is still expected to open later this week, handling scheduled appointments without cancellation but limiting other available appointments, booking them only with confirmed vaccine supply.

“The vaccine supply coming to San Francisco’s healthcare providers and the Department of Public Health (DPH) is limited, inconsistent, and unpredictable, making vaccine rollout difficult and denying San Franciscans this potentially life-saving intervention,” officials said in part Sunday.

According to the city health department, the city has administered more than 190,000 of 262,000 doses to city and regional residents, and plans to use its remaining supply for first appointments and scheduled second doses.

City officials opened the high-volume sites last month with the goal of vaccinating the city’s entire population by June 30. That would require more than 1.5 million doses in order to vaccinate more than 760,000 residents over the age of 16. officials said Sunday.
