San Francisco plans to open the city’s second mass vaccination site at the Moscone Center on Friday — a site set to serve thousands of residents daily once the city is able to secure more doses.

For now, the new site will be by appointment only and serve health care workers and people who are 65 and older, in accordance with the state’s vaccination guidelines.

Once opened, the new site will be the second planned mass vaccination site but the fourth site to have already opened in the city.

Last month, the city launched the first mass vaccination site at City College of San Francisco and then earlier this week launched a small-scale site in the city’s Mission District. Additionally, the city has opened a separate vaccination site at San Francisco State University exclusively for people 65 and older. All of the sites remain by appointment only.

“We are working every day to set up systems to get people vaccinated as soon as we have the supply,” Mayor London Breed said in a statement. “As vaccines come to our city, whether it’s through our Department of Public Health or our private health care partners, we need to do everything we can to move it quickly and efficiently.”

The Moscone Center site is being launched through a partnership between the city’s Department of Public Health and a consortium of private health insurers like Kaiser Permanente, the California Medical Association and Adventist Health, among others.

“These partnerships with health care providers are key to meeting our goal of vaccinating everyone who lives or works in San Francisco in order to help bring an end to this pandemic,” SFDPH Director Dr. Grant Colfax said.

The city is seeking to launch a third mass vaccination site in the city’s Bayview District as well as several other smaller sites in areas like Chinatown, Western Addition, Outer Sunset and Potrero Hill. Once more vaccine doses become available, the city hopes to be able to vaccinate as many as 10,000 residents per day across all of the planned sites.

San Francisco residents and those who work in the city are being encouraged to visit or the state’s website to find out about eligibility and how to make an appointment.
